germinating weed seeds in paper towel

How to germinate cannabis seeds

Germination is the process in which a new plant begins to grow from a seed. Also referred to as “popping,” germination is the very first step in starting your cannabis garden.

Cannabis seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

When acquiring seeds, you want to make sure they are matured and that they appear dark brown with lighter accents and a hard feel. You don’t want a seed that feels fresh and looks green, which indicates that the seed hasn’t reached full maturity.

What’s the best way to germinate cannabis seeds?

Cannabis seeds require three things to germinate: water, heat, and air. Because of this, there are many methods to germinate your seeds. The most common and simplest method involves the use of paper towels saturated in water.

For this method you will need:

  • Two clean plates
  • Paper towels
  • Seeds

Step 1:

Take four sheets of paper towels and soak them with distilled water. The sheets should be soaked but shouldn’t have excess water running off.

Step 2:

Take two of the paper towels and place them on a plate. Then, place the cannabis seeds at least an inch apart from each other and cover them with the remaining two sheets of water-soaked paper towels.

Step 3:

To create a dark, protected space, take another plate and flip it over to cover the seeds (like a dome).

Step 4:

Make sure the area they’re kept in is warm, somewhere between 70-90°F.

After these steps have been completed, it’s time to wait. You can check the paper towels to make sure they’re still saturated, and if they seem to be losing their moisture, you can apply more water to keep the seeds happy.

Some seeds germinate very rapidly while others can take several days. You know a seed has germinated once the seed splits and a single sprout appears.

This is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination. It’s important to keep this area sterile, so don’t touch the seed or taproot as the seed begins to split.

Transplanting germinated cannabis seeds

Once you see the taproot, it’s time to transfer your germinated seed into its growing medium. Small 2-inch pots are a good place to start.

Fill the pots with loose, airy potting soil and poke a hole in the middle about a quarter-inch down using a pen or pencil.

To transfer the seed, use a pair of tweezers to gently pick it up, then drop the seed in the hole with the taproot facing down. Lightly cover it with soil.

Next, you’ll need to water the soil. Initially, use a spray bottle to provide moisture without over-saturating the soil. You want to give the seed water, but over-watering can suffocate and kill the delicate sprout.

Pay attention to the temperature and the moisture level of the soil to keep the seed happy, and within a week or so you should see a seedling begin to grow from the soil.

Germinating seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.

This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones and which to breed with other strong plants to create a seed bank of your own.

Follow these simple steps on the best way to properly germinate your cannabis seeds, and find out how to transplant the seeds to soil after germination.

HOW TO GERMINATE MARIJUANA SEEDS

How can I germinate cannabis seeds? It is a Frequently Asked Question among most wannabe cannabis growers. Well, whenever you see a cannabis strain flourishing in a fellow connoisseurs grass farm, one thing is sure – the process of getting the favorite weed starts with germinating cannabis seeds. As of this moment, you may be asking, “where do weed seeds come from?” Ganja seeds are not something you will go to your nearest agro-vet and make your purchase. Thankfully, you are on the very website that deals in an array of cannabis seeds, as you will see on Leafly.

Also, before germinating weed seeds, you ought to ensure that your country legalizes the cultivation of pot; otherwise, you will find yourself on the wrong side of the law. We can’t insist enough that you have to order your weed seeds from a reputable seed bank as they will ensure that these goodies are supremely packaged, and with the highest chances of germination. Mature and ready-for germination seeds are mostly dark brown, and with a firm feel. That said, is the seeds are extremely wet or dry, they won’t germinate and so throwing them away is inevitable.

After getting your preferred seeds from the Amsterdam Marijuana Seeds Company, you need to ensure that the growing space is appropriately prepared to necessitate the growing of healthy ganja seedlings. Otherwise, it would be the worst idea to pop weed seeds when the growing area isn’t sufficient to enhance proper spacing of the plants.

Germinating Cannabis Seeds: Requirements

  • Water
  • Air
  • Heat.

Let’s now debunk each requirement to the entirety.

Water best gets for breaking seed dormancy. However, one ought to be careful not to under-soak or oversoak their seeds. Ideally, a day is enough to soak your grass seeds. That said, even the hardest seeds will have received sufficient water.

Provided you subject your seeds to the sufficient amounts of water, the taproot should appear through the shell. This is the critical time to ensure that the taproot also called the cannabis white tendril, gets water; otherwise, it will dry up should it lack water.

The rate of respiration in a dormant seed is meagre. This means that oxygen gets used at trace rates if all any. However, cannabis seeds require sufficient oxygen to pop. So, where does this oxygen come from when a weed seed is germinating? Well, this is the best point to understand why water is such crucial in germination.

In addition to breaking seed dormancy and keep the taproot alive, water also contains air, which is in this case oxygen. The presence of oxygen, therefore, enhances the ultimate germination of cannabis.

This is the most overwhelming part of cannabis cultivation. Picture this: cannabis seeds don’t require excessive heat or coldness. That said, you would need to play with humidity levels in such a way that the germination medium has a lukewarm temperature. Even though cannabis seeds can grow in colder areas, it may take longer, not unless you filter through the Amsterdam Marijuana Seeds and select the strain that gets described as doing well in cold regions.

We mostly advise growers that if wherever they are is extremely cold, they may need to buy incandescent bulbs and erect them above where the seeds are germinating.

While those are the basic requirements, other factors can best get considered depending on the chosen method of germination. We are going to illustrate the different ways of germinating cannabis seeds using the easiest to the most challenging practices of germination.

Cannabis Germinating Techniques

1. The paper towel method

The paper towel method of germinating weed seeds is arguably the easiest. The factors to consider when using the technique include:

  • Two plates
  • Paper
  • Neutral water
  • A mixture 40% sand and 60% soil
  • Pots for the plants
  • A fluorescent tube.

1. Place the seed between some dampened pieces of paper towel. It’s highly recommended to use distilled water to germinate your marijuana seeds.

2. Afterwards, place the marijuana seeds (in the towels) between 2 plates and put it somewhere warm. The best temperature to germinate your cannabis seeds is between 21 and 25 degrees celcius.

3. Open the plate’s only once a day just to have a look. Take note of a tiny white root tip starting to emerge from the marijuana seed. Some cannabis seeds will sprout in a day, while others need a week before they crack open.

4. Ensure that the towel will not dry out. Put a little bit of water over it every three days.

5. Once the root has come out of the marijuana seed, you have to put the cannabis seeds in a small pot filled with soil.

6. Make a little hole in the soil. Holes with half an inch deep are suffice. Plant the marijuana seed with its root facing the hole. Cover the hole with some soil and give it a little bit of water. Make sure the marijuana seeds are still covered with soil after you water them.

7. Place the pots with the marijuana seeds under a fluorescent lamp and give it a little bit of water every day.

8. Turn the lights on for about a few hours a day. After 3 to 7 day’s, you will see the first few signs of the marijuana plant. The lamp should be at least an inch above the topmost portion of the young cannabis plant in order to avoid burning its leaves.

9. After 3 to 4 weeks, the marijuana plant should be about 4 inches high and thus big enough to be transferred to a bigger pot. If the temperature allows it, you can now put them outside or place them in your indoor growing room.

2. Direct germination

The direct germination of ganja seeds is as easy as it sounds. Necessarily, the marijuana seeds will pop after getting subjected to water, where the white tendril will go downwards and start growing.

The best thing we like about the direct germination of the pot is that there is no reason to worry about the hassle you meet when the time for transplanting comes. Substantially, this method listed on our how to germinate cannabis seeds guide works across every other growing medium, but the difficulty may vary.

If you do everything right, the seeds will come out sturdily since they will not undergo any stress and will adapt to the very conditions of growth.

So, if you decide to germinate cannabis seeds directly on soil or soilless mediums, the process is all the same – make a hole between 1.5 and 2.6cm in moist soil/soilless medium, but where it gets grown, the medium shouldn’t be soaked.

1. Overnight soaking

This process typically involves the usage of a clear glass cup and soaking the weed seeds in warm water, overnight. The process is ideal for those cannabis seeds that have somewhat hard shells or those that are aged.

If the seeds are excellent, they start off by floating in the slightly warm water but sink with time. The reason for using a clear glass cup is to ensure that you may keep in pace with how the seeds germinate. Should you see a white tendril, then rest assured that your marijuana seeds have germinated!

However, the main emphasis is that the water should be slightly warm as when it’s hot, it will end up destroying the seed and inhibiting its chances of germination. The time it takes for a viable seed to sprout is dependent on the age. For instance, newer marijuana seeds germinate in a few hours after getting soaked, with old seeds taking their ample time for the taproot to penetrate through the shell. Either way, it would be worthwhile not to saturate a seed for more than 30 hours.

2. Using a germination station

A germination station best fits amateurs, even though aggressive beginners can use the technique for germinating cannabis seeds. So, what is this station? It is a tool tailored explicitly for providing a grower with the optimal conditions for germination, regardless of what is getting sprouted.

A germination station is affordable, and the grower doesn’t have to break the bank to have their tool. However, if you are genuinely on a tight budget and are convinced that going the DIY way is possible from your side, then it could be a breeze to make one.

You need to follow these simple steps:

Have a plastic dome ready

· Place the same plastic dome on a heating pad

· You have your germination station now.

A professionally manufactured germination station is ideal for amateurs since it provides all the necessities for germination and works efficiently and, of course, well.

If you buy one, using it is as easy as we are going to debunk here. Firstly, it has a seedling cube for germinating the seeds. Secondly, should you need to transplant the seedlings, you typically need to carry the cube with the seedling and plant it on where the growing medium where you have made the hole.

The roots appear from the bottommost part of the cube, so, you need to place the cube as it is on the growing medium while factoring that that medium shouldn’t be oversoaked.

3. Seedling plugs

If you are an expert, this is your thing when it comes to germinating marijuana seeds – seedling plugs and starter cubes. These plugs are already readymade and with instructions to make pot germination a breeze.

Using it involves placing the marijuana seed of your choice in the plug or cube, follow the watering instructions, and the seedlings will sprout as soon as possible since they’ll be having the factors necessitating their ultimate growth.

So, how do these tools work? Well, a plug or a cube has a hole, where the cannabis grower will place their seed. That said, one needs to put that very seed on the designated hole and place their finger on the topmost part to make the seed enter the plug or cube well.

Provided the seed is viable; this is one of the few methods that all marijuana growing experts claim to guarantee 100% sprouting chances.

Transplanting your germinated cannabis seedlings

You now have the 5 top-tier procedures for necessitating the cannabis seeds germination. Now that the highest chances are that all the weed seeds will germinate, how do you go about planting and taking care of the seedlings?

The first step to follow is ensuring that you have a ready growing medium. This could be an outdoor, indoor, or hydroponics mediums. Let’s take an example that you would like to grow cannabis in pots. The critical idea is ensuring that you fill the growing pot with sufficient soil while ensuring it is loose to make the seedling flourish stress-free.

Use a pencil to bear a hole up to ¼ inches deep and transfer the seedling into the very hole using a pair of tweezers. Using your bare hands may lead to the distortion of the taproot/ white tendril. Also, ensure that this taproot is what faces downwards, and cover the seedling-to-be in a thin soil layer.

Ensure that the seedling gets ample moisture, and if need be, use a pH meter for accuracy purposes. You don’t need to pour loads of water on the seedling as it will perhaps die. Instead, use a sprayer bottle to water your cannabis seedling.

The seedlings should be above the ground within a week, and the chances are that if it doesn’t within 9 days, your seed may have gotten spoilt. Also, heat is primal and grow lights may be used to up the chances of your seedling sprouting. Happy cannabis cultivation!
