How to grow marijuana outdoors: a beginner’s guide
Growing cannabis is a fun and rewarding experience, but it is also challenging and takes a certain amount of time and money. For a first-time grower with limited resources, an indoor grow is probably too costly of an option.
The good news is that a small outdoor garden can yield plenty of quality cannabis without a large monetary investment. If you have access to a sunny spot in a private yard or even a balcony, terrace, or rooftop, you can successfully grow cannabis.
This guide to outdoor growing will go over all the different factors you need to consider in order to set up your first outdoor marijuana grow.

Benefits of growing weed outdoors
- Low costs: Relying on the power of the sun, you won’t need to spend a ton of money on an outdoor grow. You’ll need some soil, fertilizer, seeds or clones, and maybe a small greenhouse to get them started. You won’t need to pay for electricity for lights, AC units, or dehumidifiers, and you can even collect rainwater.
- Big yields: The sky’s the limit with outdoor plants—you can let them get as big and tall as you want, as long as they’re manageable. One plant can potentially yield up to a pound of weed! Growing a handful for yourself is plenty. With an indoor grow, your space is a lot more restricted.
- Environmentally friendly: Indoor grows can be wasteful, using a ton of electricity to power all those lights, fans, and other equipment. The sun and the wind are free!
- It’s fun and relaxing: Don’t underestimate the therapeutic value of gardening. It’s relaxing to spend some time outside, roll up your sleeves, and get your hands dirty for a while. And there’s nothing better than smoking something you grew yourself.
Step 1: Consider the climate
It’s crucial to have a good understanding of the climate in the area you’re going to grow. Cannabis is highly adaptable to various conditions, but it is susceptible to extreme weather.
Sustained temperatures above 86°F will cause your plants to stop growing, while continued temperatures below 55°F can cause damage and stunting to plants, even death.
Heavy rains and high winds can cause physical damage to plants and reduce yields, and excessive moisture can lead to mold and powdery mildew, especially during the flowering stage.
In addition to weather patterns, you need to understand how the length of day changes throughout the seasons in your area. For example, at 32° N latitude (San Diego), you will experience just over 14 hours of daylight on the summer solstice (the longest day of the year), while at 47° N (Seattle), you will have about 16 hours of daylight on the same day.
Understanding the amount of sunlight throughout the year is crucial to causing plants to “flip” from the vegetative to flowering stage, when they start to produce buds.
It’s good to utilize local resources, as experienced gardeners in your area will have a wealth of knowledge about growing flowers and vegetables, and that information can also be applied to growing cannabis. If you have some experience gardening and growing veggies, you will probably find that growing cannabis outdoors is a fairly easy endeavor.
Step 2: Pick a space for your outdoor grow
Choosing a space for your outdoor grow is one of the most important decision you’ll make, especially if you’re planting directly in the ground or in large immobile containers.
Your cannabis plants should receive as much direct sunlight as possible, ideally during midday, when the quality of light is best. As the season changes and fall approaches, your plants will get less and less sunlight throughout the day, which will trigger the flowering stage.
Having a constant breeze is good for your plants, and especially in hot climates. But if you live in an area with a lot of high winds, consider planting near a windbreak of some sort, like a wall, fence, or large shrubbery.
Finally, you will want to consider privacy and security. A lot of people want to conceal their gardens from judgmental neighbors and potential thieves. Tall fences and large shrubs or trees are your best bet, unless you live in a secluded area. Also, most state laws require that you keep cannabis plants concealed from the street.
Some growers plant in containers on balconies or rooftops that are shielded from view, while some build heavy-gauge wire cages to keep thieves and animals at bay. Whatever you decide, think about how big you want your final plant to be—outdoor cannabis plants can grow to 12 feet tall or more, depending on how much you let them go.
Step 3: Decide on cannabis genetics
The success of your outdoor cannabis grow will also depend on choosing the right strain to grow for your particular climate and location. If you live in an area with a history of cannabis growing, chances are good that many strains will successfully grow there, and some may have even been bred specifically for your climate.
Seeds vs. clones
Plants grown from seed can be more hearty as young plants when compared to clones. You can plant seeds directly into the garden in early spring, even in cool, wet climates.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with. If your seeds don’t come feminized, you could end up with both males and females, in which case you’ll need to sex them out to get rid of the males (only females produce buds).
Even when you do have all female plants, each will be a different phenotype of the same strain. To get the best version of that strain, you’ll need to select the best phenotype, which can be a lengthy process. A lot of beginning growers start with feminized seeds.
Depending on the legality of cannabis in your state, you may be able to buy clones or seedlings from a local dispensary. Some growers stay away from these because they feel they aren’t as sturdy as growing plants from seed.
Autoflowering seeds are another popular choice for outdoor growing, as they start blooming as soon as they reach maturity regardless of the length of day. You can either have a quick-growing crop, or fit multiple harvests into a year with autoflowering cannabis.
The downside to autoflowering cannabis is they tend to be a lot less potent.
Step 4: Acquire some soil
Soil is made up of three basic components in various ratios:
You can plant directly in the ground or buy soil and put it in pots. Cannabis plants thrive in soil rich with organic matter, and they need good drainage. If you decide to plant directly in the ground, you’ll need to understand your soil composition and amend it accordingly.
Heavy clay soils drain slowly and don’t hold oxygen well, so they will need to be heavily amended. At least a month before you plant, dig large holes where you’ll be placing your cannabis plants and mix in big amounts of compost, manure, worm castings, or other decomposed organic matter. This will provide aeration and drainage, as well as nutrients for the plants.
Sandy soil is easy to work, drains well, and warms quickly, but it doesn’t hold nutrients well, especially in rainy environments. Again, you will want to dig large holes for your plants and add compost, peat moss, or coco coir, which will help bind the soil together. In hot climates, sandy soil should be mulched to help with water retention and to keep roots from getting too hot.
Silty soil is the ideal growing medium. It’s easy to work, warms quickly, holds moisture, has good drainage, and contains a lot of nutrients. The best silty soil is dark crumbly loam—it’s fertile and probably won’t need any amending.
If you really want to ensure good results and minimize headaches, you can get your soil tested, which is easy and relatively inexpensive. A soil testing service will tell you the makeup and pH of your soil, notify you of any contaminants, and recommend materials and fertilizers to amend your soil.
Step 5: Get some fertilizer
Cannabis plants require a large amount of nutrients over their life cycle, mainly in the form of nitrogen, phosphorus, and potassium. How you choose to feed them will depend on the composition of the soil and your own methods.
Commercial fertilizers aimed at home gardeners can be used if you have a good understanding of how they work and what your plants need. But a first-time grower might want to avoid these, particularly long-release granular fertilizers.
Best nutrients for an outdoor grow
You can purchase nutrient solutions designed specifically for cannabis from your local grow shop, but they are usually expensive and can damage soil bacteria—they are generally composed of synthetic mineral salts and intended for indoor growing.
Organic fertilization takes full advantage of microbial life in soil and minimizes harmful runoff. There are many different natural and organic fertilizers available at local home and garden stores, like blood meal, bone meal, fish meal, bat guano, and kelp meal.
Start off with fertilizers that are inexpensive and readily available. Some of these materials release nutrients quickly and are easily used by the plant, while others take weeks or months to release useable nutrients. If done correctly, you can mix in a few of these products with your soil amendments to provide enough nutrients for the entire life of your plants.
Again, getting your soil tested can be very useful and will tell you how to amend your soil and what types and amounts of fertilizer you should use. If you are unsure how much to use, be conservative—you can always top dress your plants if they start to show deficiencies.
Step 6: Choose your containers
You may need to put all of your plants in containers if you don’t have great soil. Also, if you’re unable to perform the heavy labor needed to dig holes and amend soil, containers may be the only way for you to grow your own cannabis outdoors.
If you don’t have a suitable patch of earth to make a garden, containers can be placed on decks, patios, rooftops, and many other spots. If needed, you can move them around during the day to take advantage of the sun or to shield them from excessive heat or wind.
You can also use common cannabis nutrients designed for indoor growing because you will be using premixed soil. This will take much of the guesswork out of fertilizing your plants.
However, plants grown in pots, buckets, or barrels will likely be smaller than those planted in the ground because their root growth is restricted to the size of the container. In a broad sense, the size of the pot will determine the size of the plant, although it’s possible to grow large plants in small containers if proper techniques are used.
In general, 5-gallon pots are a good size for small to medium outdoor plants, and 10-gallon pots or larger are recommended for big plants. Regardless of size, you’ll want to protect the roots of your plants from overheating during warm weather, as pots can quickly get hot in direct sunlight. This will severely limit the growth of your plants, so be sure to shade your containers when the sun is high in the sky.
Step 7: Give your cannabis plants water
While outdoor cannabis gardens have the benefit of utilizing rain and groundwater, you will most likely need to water your plants frequently, especially in the hot summer months. Some giant cannabis plants can use up to 10 gallons of water every day in warm weather.
Growers who live in hot, arid places will often dig down and place clay soil or rocks below their planting holes to slow drainage, or plant in shallow depressions that act to funnel runoff toward other plants. Adding water-absorbing polymer crystals to the soil is another good way to improve water retention. Water your plants deeply in the morning so they have an adequate supply throughout the whole day.
If you live in a particularly rainy climate, you may need to take steps to improve drainage around your garden, as cannabis roots are susceptible to fungal diseases when they become waterlogged. These techniques include:
- Planting in raised beds or mounds
- Digging ditches that direct water away from the garden
- Adding gravel, clay pebbles, or perlite to the soil
If you’re using tap or well water, it’s a good idea to test it first. This water can contain high levels of dissolved minerals which can build up in soil and affect the pH level, or it can have high levels of chlorine which can kill beneficial microorganisms in soil. Many people filter their water.
Plants grown in hot or windy climates will need to be watered more frequently, as high temperatures and winds force plant to transpire at a quicker rate.
Remember that over-watering is a common mistake made by rookie growers—the rule of thumb is to water deeply, then wait until the top inch or two of soil is completely dry before watering again. An inexpensive soil moisture meter is a good tool for a beginner.
Step 8: Protect your cannabis plants
Without the ability to control the environment as easily as you can indoors, outdoor cannabis growers have to protect their plants from storms and other weather events that could damage or even kill plants.
Temperatures below 40°F can quickly damage most varieties of cannabis, so if you live in a climate where late spring or early fall frosts are a common occurrence, try using a greenhouse or other protective enclosure.
High winds can break branches and overly stress your plants. If your garden is located in a particularly windy spot or if you’re expecting a particularly heavy blow, set up a windbreak. This can be as simple as attaching plastic sheeting to garden stakes around your plants.
While helpful for watering your garden, rain is generally seen as a nuisance by cannabis growers. It can severely damage your crop and cause mold and mildew. You especially don’t want rain on your cannabis plants when they are flowering.
You can construct a DIY greenhouse or even just use plastic sheeting and stakes to build a temporary shelter over your plants when you know rain is on the way.
Protecting your cannabis garden from pests can be challenging. Depending on where you live, you might have to keep large animals like deer at bay by building a fence around your crop.
But the more difficult challenge is dealing with the vast array of crawling and flying insects that can attack your plants.
The best protection is to simply keep your plants healthy. Strong, vigorous cannabis plants have a natural resistance to pests that makes minor infestations easy to deal with. It’s also a good idea to keep your cannabis plants separate from other flowers, vegetables, and ornamentals, as pests can easily spread between them.
Examine your cannabis plants a few times a week with an eye out for pests. An infestation is far easier to deal with if caught early.
There are many organic pesticides designed for use specifically on cannabis, and beneficial insects are also a great option.
You should now have enough knowledge to successfully start your own outdoor cannabis garden. Cultivating and growing plants is an enjoyable and rewarding pastime, so remember, spend lots of time with your plants, and have fun!

7 Tips to Improve Cannabis Bud Quality
by Nebula Haze & Sirius Fourside
Table of Contents
- Start with Top-Shelf Genetics – get the effects and appearance you want! Your grow skill makes a huge difference, but a plant can’t overcome its genes! If you want buds that are potent, dense, sparkly or purple/pink, you need the right genetics.
- Give Your Cannabis Lots of Light! – this increases yields, density and potency
- Nutrients & Supplements – learn about smell enhancers, bloom boosters and bulk builders!
- Better Taste, Better Smell – learn other techniques to increase terpene content so buds taste and smell better
- Manipulate Temperature & Humidity in the flowering stage to increase resin production (“glitter” and stickiness), bring out colors like pink or purple & prevent smells from burning away
- Great Air Flow Around Every Cola – you can gain surprising increases in the size and density of your buds by making sure that every cola gets lots of direct light and good air flow from the beginning to the end of the flowering stage. Cannabis is wind-pollinated in the wild and so more energy is put into buds that have been exposed to a breeze from when they first started forming.
- Master the Basics of Growing – especially harvesting, trimming and drying/curing! Although a lot of growers don’t pay as much attention to what happens to plants after harvest as during the grow itself, these 3 post-harvest factors determine almost 50% of your final bud appearance. Properly drying/curing also intensifies smell and increases bud potency!
Have you ever had weed that knocks your socks off? The kind of cannabis buds that people brag/warn their friends about?
I’m talking about the really really good stuff!
The truth is, you can successfully grow cannabis with very little effort, make a ton of mistakes, and still harvest buds that will do the job.
But have you ever wondered how people grow truly top-shelf buds? The kind of bud that beats the marijuana you get in a dispensary?
If so, you’re in luck, because today I’m going to teach you 7 tips to consistently growing top-tier quality cannabis buds with effects that will stick in your memory for years to come. Plus, I’ll teach you how to make your cannabis look pretty!
1.) Start with Top-Shelf Genetics
It’s really tough to get truly top-shelf buds if you start with mid-grade seeds, clones, or the dreaded bagseed; you’re giving yourself a much higher chance of disappointment because no growing method can overcome genetics!
These buds were both grown in the exact same setup at the same time, but have different genetics. Look how differently the buds turned out! Choosing the right strain lets you choose the looks and effects you want!
When I first started growing, I would grow any seeds I could find. These would usually grow pretty well but the resulting weed never ended up being as good as the buds I found them in. And sometimes the buds would be airy and not-that-potent.
After a few attempts at growing bagseed, I tried buying marijuana clones from the local dispensary with crazy strain names like “Super Grand Daddy Purple” and “Grapefruit Bubblegum Kush,” but my yields and results still left a lot to be desired. It’s not that there’s any inherent problem with clones – clones are awesome! – but I got a feeling these plants weren’t really the strains the dispensary claimed them to be. I didn’t have any grower friends at the time and I thought bag seed and local clones were my best choices.
Until I discovered online seed banks.
Ever since I started buying seeds from a reputable cannabis seed bank and getting my chosen strains shipped to me, I have been able to consistently produce high-quality buds!
Getting your genetics from a reputable breeder is key to producing gorgeous and potent buds!
If you want to grow buds that are pink or purple, you must choose the right genetics!
Just switching to better seed stock caused a dramatic increase in my yields without any other changes. But even more importantly, the quality of my harvests drastically improved. Not to mention the freedom of being able to choose which strain you want to grow instead of hoping to find a good seed in your buds!
Clones are still a great way to start a grow with good genetics, but you have to make sure you always get clones from a trustworthy source!
If you want to take your quality to the next level, don’t start with just any clones or seeds. Search for the right, true quality genetics and don’t be afraid to research to make sure you’re getting exactly what you want! Good seeds cost more than bagseed, but the money you pay for quality is worth it, especially when you consider what you’re getting in return!
2.) Give Your Cannabis Lots of Light!
If you want great bud, you have to provide plenty of light!
When you start a grow with good genetics – from good seeds or clones – your plant has the potential for a high level of quality (yields, potency, resilience). However, it’s nearly impossible to get your buds to reach that potential if you use lights that are underpowered.
Powerful grow lights like HPS, LECs or LEDs produce the biggest and most dense buds
For example, there’s no amount of plant training or growing skill that can make up for the amount of light produced by an incandescent bulb; the bulb simply doesn’t have what it takes to do the job.
Similarly, growers can have the same problem when they try to grow a larger plant with a few small CFLs or T5s. Although CFLs and T5s make great growing lights and produce a high-quality product, it’s important to pick the right tool for the job. These two types of lights are better at stealth, discretion, and smaller grows than producing lots of super potent bud.
Strong, bright light is what powers the growth of buds in the flowering stage – light is like “food” for your plants!
When it comes to indoor cannabis gardening, more light is better…to an extent. If you give your flowering cannabis plants all the light they can handle without giving them too much, it increases your potency, density and yields.
Strong, bright light is a crucial part of reaching a strain’s full potential!
Strong light is incredibly important for the highest bud density, potency and yields!
3.) Nutrients & Supplements to Increase Bud Quality
First, before adding any special supplements, you need to make sure you’re giving your plant the correct base nutrients in the flowering stage.
Base Nutrients in the Flowering Stage
- Low Nitrogen (N) – Give your plant relatively low levels of Nitrogen, especially in the second half of the flowering stage when the plant has stopped growing vegetatively and buds are fattening up. The plant needs a lot of Nitrogen for vegetative growth but doesn’t need nearly as much for making buds. In fact, too much nitrogen in the ripening stage can discourage bud production and hurt your yields.
- Plenty of Phosphorus (P) – Phosphorus is incredibly important to flower production and giving plants plenty of Phosphorus in the flowering stage will help increase the total number of flowers
- Potassium (K) – Potassium is often overlooked compared to Phosphorus (which is often considered a bud booster) but Potassium may actually be even more important! Providing a good source of Potassium increases the size and density of each individual flower.
In general, when it comes to feeding nutrients in the second half of the flowering stage, less is more! Keeping nutrient levels low can also improve the taste of your final buds because high nutrient levels are associated with a chemical taste to the buds.
Giving cannabis the right ratios of nutrients during the flowering stage will greatly increase the quality of your bud!
Supplements in the Flowering Stage
Supplements in the flowering stage come in many different flavors, and they have different goals or purposes
- Sugar or carbohydrates – improve taste/smell and increase bulk. Some of these, like the Botanicare Sweet Carbo Line, not only include sugar, but also certain terpenes and esters that are stored unchanged in plant buds, giving your buds unique subtle flavors like grape, citrus, berry, and “raw” (which is just a generally sweet smell).
- “Bloom Enhancers” – These offer a variety of non-nutrient ingredients that may help the plant grow better or more efficiently in some way by improving processes or providing the plant with amino acids and humic acids, so the plant doesn’t have to make everything itself.
- PK Boosters & “Shooting Powders” – With this type of supplement, the main ingredients are just Phosphorus and Potassium because they are important for flowering. These also sometimes contain some amount of sulfur. In general, use these sparingly as they’re usually very potent! And don’t forget that every quality base Bloom nutrient should already contain plenty of P and K.
Often, bloom supplements will include a mix of some or even all of these types of ingredients! It can definitely get a little confusing so I’ll try to break it down a little ?
Sugar or Carbohydrates
A cheap alternative to expensive sugar-based bloom boosting supplements is blackstrap molasses. Giving this to your plants for the last few weeks before harvest can help them get bigger and smell/taste better. It’s not specially made for plants; it’s the regular stuff you’ll find in your kitchen or at the grocery store. Blackstrap molasses adds sugars, amino acids and trace minerals. Unfortunately for hydro growers, anything organic like molasses is not suitable for a hydroponic reservoir! But molasses works great for soil and coco growers ?
For last 2-3 weeks before harvest, give 1/2 tsp of Blackstrap Molasses per gallon when watering (for soil or coco coir)
For those who prefer something in a bottle, I’m really intrigued by Botanicare’s Sweet Carbo line. According to Botanicare:
The natural esters in Sweet are easily absorbed by the plant, but are not broken down further once deposited within the plant tissue. This means that as new flowers develop they will contain small amounts of these natural esters which contribute to the overall flavor and aroma of the finished product.
They offer flavors such as grape, citrus, berry, and “raw” (which is just a generally sweet smell). These should be used throughout the flowering stage to help build smell/flavor in the buds as they mature. However, since these contain a small but significant amount of magnesium, they should not be used while flushing during last 2-3 weeks before harvest. At this point, the smells have already been deposited into the buds. Another cool thing about these supplements is they contain amino acids and some other enhancers, so it’s kind of like getting a lot of different products at once.
Other growers who’ve tried the “raw” version have said they can definitely notice an increase in the amount of “sweet” smell in their buds and it’s made me curious/jealous. I plan to use Sweet Grape as my primary supplement for the flowering stage in a future grow; I’ll report back whether buds actually smell like grape, sweet or plain ol’ cannabis ?
The jury is still out and which is the most effective supplement, but many growers are happy with bloom promoting supplements that include sources of…
- amino acids
- humic acids
- trace minerals
I personally don’t use this type of supplement so I can’t recommend a particular one, but some of the most popular cannabis supplements based on this type of formula include…
- Floralicious Plus (by General Hydroponics)
- Liquid Karma (by Botanicare)
- Diamond Black (by General Organics)
Note: These are only for soil or coco coir! (Since these supplements contain a lot of organic materials like guano and fishmeal, they are not suitable to hydroponic reservoirs)
PK Boosters & “Shooting Powders”
The supplements listed above use ingredients that add only tiny amounts of base nutrients (NPK). This means that they have less of a chance of overwhelming your plant with too high levels of nutrients (which can be easy to do if you’re adding a lot of supplements!).
However, this last set of nutrients directly adds P and K. If you’re using a regular Bloom nutrient already, this can make it really easy to go overboard with P and K. Whenever using this type of nutrient, a tiny amount goes a really long way! Whenever possible, try to choose a supplement by the same company as your base nutrients – this will help prevent negative interactions between the nutrients and the supplements. In general…
- Phosphorus (P) increases number of flowers
- Potassium (K) increases weight/density of flowers
These sometimes also come with a small amount of Sulfur (S), and possibly other ingredients like amino acids, trace minerals and/or sugar like the supplements above.
Suitable for Hydro, Soil or Coco – Supplements to Increase Yields/Density with extra P & K
- Liquid Koolbloom (by General Hydroponics)
- Hydroplex (by Botanicare)
- Beastie Bloomz (by Fox Farms)
4.) Better Taste, Better Smell – Increase Terpene Content
The smell and scent of cannabis buds are produced by plant chemicals known as “terpenes” (also “terpenoids”, which are a class of terpenes).
Terpenes contribute to the flavors of many household spices (like cinnamon, rosemary, cloves and ginger) and help create the scent of most flowers.
The unique combination of terpenes and terpenoids produced in cannabis flowers (buds) cause most of their taste and smell as well.
There are a variety of ways to increase the terpene content of your buds so you produce cannabis that tastes and smells great, and there are also a couple of common mistakes you should know about that can actually ruin the taste and smell of your buds.
5.) Maintain Proper Temperature and Humidity
Maintain daytime temperatures around 65-80°F (18-26°C) in the flowering stage unless you’re using CO2 which does best at around 80-90°F (26°-32°C). However, even if you’re using CO2, most growers recommend you back off and bring the temps down to 65-80°F for the last two weeks before harvest.
Night temperatures should be kept around 68-75°F (20°-24°C) for most strains. Too-cool temps increase the chances of bud rot, which thrives in the 60°F (15°C) range, and freezing temperatures can actually damage or even kill your plants.
However, if you’re growing a strain that turns color, keep in mind that some of these strains will only show their color when night temperatures are at least a few degrees cooler than during the day in the flowering stage.
Some strains need slightly cooler night temperatures before their buds will turn colors. For example the buds of this Auto Frisian Dew turned bright purple after it started getting below 70°F (21°C) temperatures at night.
Humidity stumps a lot of new growers and causes several unexpected problems.
Maintaining higher humidity during the vegetative stage will reduce salt levels within the plant while encouraging healthy and lush growth.
During the vegetative stage, if humidity drops below 40%, especially anywhere below 25%, it can cause problems that look like nutrient deficiencies or light/heat stress!
But in these cases, just adding a little moisture to the air does wonders, even if you don’t change anything else.
During the flowering stage, your cannabis plants actually prefers less humidity!
Decreasing moisture in the air (lowering the humidity) during the flowering stage helps prevent mold and actually may increase trichome production in your buds! For best results, keep humidity 40%-50% during the flowering stage.
Lower humidity levels in the flowering stage helps promote trichome production, which increases the amount of “glitter” you see on buds
“But I’ve never worried about humidity and my plants are fine…”
The truth is, you can successfully grow your marijuana plants in high or low humidity, even if growth isn’t perfect. This is the primary reason why many growers – especially new ones – forget about humidity altogether.
New growers also tend to hastily spend money on CO2, supplements or expensive nutrients when controlling the humidity in their setup could make a much bigger difference in their final product.
So if you’ve realized that your humidity is far higher or lower than what’s recommended, you may be able to make a simple, relatively cheap change to dramatically improve the vibrancy of your plants.
For growers in really dry or humid areas, it can make a big difference to buy a humidifier/dehumidifier and make sure they’re always providing the optimum humidity levels.
And there’s one more insider trick you need to know about humidity: So you know you need to keep humidity in 40-50%RH range for the flowering stage, but there is one extra trick… Use a dehumidifier to drop the humidity down as low as you possibly can for the last 2-3 weeks of flowering (I’ve gotten the humidity as low as 25%).
This extreme dryness will encourage the buds to seal and protect themselves with additional resin (in other words, a sparkling outer layer of THC-heavy trichomes).
As an added bonus, this trick also gets your buds prepped for a successful, mold-free drying process because your buds have already given up some of their moisture.
6.) Make Sure Grow Room has Strong Air Flow & Good Ventilation
This is yet another factor having to do with air quality (we already listed temperature and humidity).
Over time, any grower (especially indoor growers) will see that great air quality is a big contributor to star-quality buds. Air flow and ventilation are essential if you want to create perfect air quality.
For 1-3 plants smaller to mid-sized plants, you’ll probably be fine with an oscillating fan or two. With a big grow and hot lights, you’ll need a better exhaust system to ensure proper airflow, but it can be easy to set up!
7.) Master the Basics – Especially Drying & Curing
You probably know that in order to get the best results, your plants need to make it through the majority of their lifecycle without major problems.
But although your growing methods are incredibly important, one of the most important things to focus on is when you harvest, as well as the process of drying/curing your buds after harvest.
In fact, the things you do during and after harvest, including drying/curing, makes up almost 50% of your final bud appearance!
Drying/curing the right way will make buds smell better, look better, be more dense, and buds will actually feel more potent!
If you haven’t really been paying attention during the drying/curing part of your grow, you should focus here for the greatest gains in quality!
Drying buds slowly and then curing them in glass mason jars for 2-4+ weeks helps “tighten up” buds so they are more dense. Curing also intensifies smell and increases potency!
What else to pay attention to during the grow?
A lot of mistakes that won’t kill your plant (like nutrient burn, nutrient deficiencies, and heat stress) can often still damage the overall appearance of your buds, especially big problems that happen after the beginning of the flowering stage while buds are in the process of forming.
More importantly, too many problems during the flowering stage can reduce the maximum potency your plant can achieve!
So in order to get the best yields along with beautiful buds that sparkle in the light, you need to gain a complete understanding of the basics of growing. It’s also important to provide your plants with a good growing environment.
But if you were to focus on just ONE thing to improve with your grow, the factor that makes the biggest difference to your quality (besides the strain) is the drying and curing process.
