The best strains to grow in a greenhouse

Before investing in a greenhouse, it’s a good idea to think about all the problems often involved with growing weed outdoors. Unpredictable weather, nosy neighbours, marijuana theft, exposure to diseases and pests, insect cross-pollination that could ruin your perfect strain – all these could lead to a poor harvest and ruin your efforts.

Growing your cannabis in the safety of a greenhouse is an effective way of preventing or reducing all these adverse situations. Using a greenhouse provides a controlled environment which your weed plants love. Moreover, after the initial set up costs, a greenhouse is an extremely economical and environmentally friendly way of maximising the natural resources of light and heat.

Yet, some types of weed are better suited for greenhouse life than others. The temperature in the greenhouse, for example, is vital to how well the strain can photosynthesise. Its therefore most important to select the right strain for your growhouse culture, but what are the best strains to grow in a greenhouse?

Safeguarding the genetic makeup of your cannabis strain

One particular advantage offered by a greenhouse is the maintenance of the genetic stability and quality of their strains. To establish a successful growing season with maximum yield, cultivators need to choose high-quality strains of marijuana. Viewing your seeds as an asset is vital if you want to optimise the benefits of growing in the confines of a greenhouse. Allowing your quality investment to grow in the wilds of your garden gives you the likelihood of altering its genetic composition when they become cross-fertilised via outside interference, such as wind, the touch of insects, animals or humans.

Top 5 best strains to grow in a greenhouse

The dual actions of spending money on high-quality seeds and growing them in a greenhouse should result in an excellent yield throughout the year while maintaining the quality of the strain. At you will find seeds to suit virtually all set-ups and climates. Here are our top five strains for growing in a greenhouse:

1. Blue Dream

Blue Dream is the best strain to grow in a greenhouse and in most cases, guarantees its full potential. A wonderful strain with beautiful purple and violet hues, this marijuana plant looks highly attractive.


Blue Dream Auto is a hybrid with a lemony and wood-smoke aroma and a taste with hints of citronella, cedar, woodland berries and Haze. The result is a long-lasting, powerful high that provides clarity and promotes conversation and socialisation. For Haze enthusiasts and connoisseurs.


Blue Dream Auto will thrive indoors if given good lighting and a rich diet. Outdoors it thrives in temperate, dry, warm and Mediterranean climates, and in a greenhouse in places where sunshine and heat are unreliable. If you are thinking of investing in seeds to grow in a greenhouse, Blue Dream should undoubtedly be included in your list of contenders.

2. Gorilla Glue

Gorilla Glue is a medium-density hybrid and features very light green calyxes and notoriously sticky trichomes. The aroma of the Gorilla Glue flowers is sweet with hints of sharp sourness that tends to vary from batch to batch. Burnt flowers produce a very strong skunk perfume that hangs heavily in the air.


Gorilla Glue was bred explicitly for maximum THC content, and the flavour of Gorilla Glue can be a bit bland compared to other strains. The high is very gentle – an initial euphoric rush leading into several hours of mild relaxation.


Gorilla Glue loves to be grown in a greenhouse and will reward you with increased yields. Take care that the pots are large enough to avoid root bind. Don’t overwater and take great care when providing nutrients, ensuring that it receives the correct ratio at the right time.

3. White Widow

White Widow is famous worldwide, especially among travellers to Amsterdam, perhaps the most cannabis-friendly city in the world. Amsterdam and other Dutch cities that allow tourists to smoke cannabis regularly sell White Widow in their coffee shops.


There is a little something about this variety that makes it sell very well in the Netherlands. Perhaps it’s that lovely pine aroma? It might be the sensual yet cerebral high, which finds a smart balance between the Sativa and Indica elements of this strain. The high results from the powerful psychedelic impact of its 19% or more THC.


White Widow is one of the trickiest strains to grow, which makes it ideal for growing in a greenhouse as it is easier to get the temperature and humidity levels precisely right. Keep levels above 21 degrees Celsius by day and don’t let them drop below 15 at night. Humidity levels should be high during the germination phase and then decreased gradually back until flowering when they should be as low as 30 to 40%. To do this, you will need greenhouse windows that open and a hygrometer.

4. Super Silver Haze

Super Silver Haze is a weed that tends to give users a generous body high, rather than a cerebral buzz. It relaxes the smoker and might even send them to sleep rather than filling them with energy

Super Silver Haze has scents and flavours that are best described as pine and fruity, which provide a sense of well-being after smoking. This feeling is loved by most smokers, which explains the popularity of Super Silver Haze. The finest effects of Super Silver Haze are euphoria, energy, bursts of creativity, increased appetite and a full-body high.


While Super Silver Haze might be more forgiving than other Sativas, you need to keep an eye on its nutrition and environment, which makes it ideal for growing in a greenhouse. This strain enjoys warmth and humidity, so be sure the temperature of your greenhouse is a constant between 70-80ºF (21-27ºC). Cultivators in the Northern Hemisphere can expect to harvest in mid-October.

5. Northern Lights

We end our top 5 best strains for greenhouse culture with another popular variety from Dutch coffee shops. The classic Indica, Northern Lights. Dispensaries in North America have also experienced high demand for this variety. Its Indica qualities present a distinctive taste. The spicy notes of incense, earth and pine recall its Afghan heritage. The fruity flavours of these feminised seeds combine to create a complex and sensual profile.


Northern Lights combines an uplifting high with a massive stone resulting in a very balanced and long-lasting buzz.


Northern Lights is one of the most straightforward strains of cannabis to grow, and Northern Lights Auto is even easier. If growing in a greenhouse, you can look forward to rapid growth and generous yields, taking as little as eight weeks to reach 800 gr/m2!

Indoor, Outdoor and Greenhouse Cannabis: What’s the Difference?

Monday January 29, 2018

L egal cannabis sales have afforded customers the ability to choose from many forms of marijuana – edibles, topicals, concentrates, and so on – and in states like Oregon, those options include choices between indoor, outdoor, and greenhouse grown cannabis, too. But how exactly does the result differ between the three types of marijuana? The answer may surprise you.

The Truth About Outdoor Cannabis

Cannabis is designed to withstand variable conditions to flourish for generations (in other words, it grows like a weed), and has evolved all sorts of traits to help it withstand environmental stressors: quick grow periods, beautiful accessory coloring, sturdy stock, and so on.

But marijuana’s fantastic ability to evolve and adapt to its environment has also brought with it some unfavorable consequences. For example, stressed female cannabis plants may produce seeds to protect the next generation, and a quicker growth period or weather fluctuations may result in lower trichrome content when grown outdoors.

Outdoor cannabis may also be lacking in aesthetics (buds won’t be as pretty) which is due to a few factors. First, marijuana grown outdoors will stretch as it grows because of the abundant light and ample space which results in fluffier weed instead of those dense nugs you see in connoisseur magazines. Likewise, large harvest sizes produced by outdoor grows may result in a sloppy trim job as trimmers trudge through pound after pound of product come harvest time.

But that doesn’t mean outdoor cannabis doesn’t have its place in the industry. By growing outdoors, cultivators can produce large quantities of product with minimal resources which translates into a cheaper product for the consumer and helps cannabis remain accessible for those who need it.

Outdoor cannabis makes an excellent choice for DIY cannabis products, too!

We recommend strains like Critical Mass, Killer Queen or Sour Diesel for outdoor grows due to their high, potent yield with minimal effort. Resilient to the elements, these strains will thrive on natural sun and produce large yields and picture-perfect colas when fed and watered correctly.

Potency and Yield of Indoor Grown Cannabis

What started as a covert solution to an illegal trade has become the secret to cultivating premium, award-winning strains. When growing cannabis indoors, growers can focus their attention on a smaller number of plants, monitoring growth patterns, nutrient needs and so on with ease. This hands-on approach has allowed growers to perfect their practice in controlled environments, using a variety of techniques to increase potency, perfect flavor and improve appearance all within a smaller space.

Buds grown indoors tend to be smaller and denser (with a much cleaner trim job), but their trichome content is typically much higher. The flavor and cannabinoid profile of indoor cannabis plants are often on point, as well, thanks to the ability of growers closely monitor the maturation rate of trichomes for perfectly timed harvests.

This increased potency and premium flavor has made indoor cannabis especially appealing to connoisseurs who are willing to pay top dollar for their premium cannabis products. Of course, this also means higher prices for the average consumer, as well, but fortunately, there’s a happy medium that harnesses the best of both worlds: greenhouse cannabis.

Ideal strains for growing cannabis indoors include Skunk #1, Strawberry Haze, and Big Wreck because they do well in controlled environments, producing tall, dense buds in relatively small spaces. Indoor cannabis flowering time is often shorter than outdoor-grown cannabis and is much easier to tell when it is time to harvest.

Growing Cannabis in Greenhouses

Cannabis can be a finicky plant, producing seeds or dropping its trichome production as the result of stress, so keeping the girls happy and stress-free while they grow is imperative to developing quality cannabis. That means controlling the environment, the light schedule and all contaminants that may make their way into a grow area, as well.

Greenhouses allow growers to monitor their crops on a larger scale and grow them continuously throughout the season.

They utilize sunlight whenever possible, thus reducing electricity costs while keeping the plants enclosed and protected from the elements at all times. Provided the plants are trained properly using netting to support substantial growth while encouraging airflow, greenhouse-grown cannabis can easily be grown pesticide and mildew free, and the potency comparable to indoor cannabis despite its potentially larger size.

Some of the best strains to grow in a greenhouse include Northern Lights, Tahoe OG, and Jack Flash due to their large size, resistance to mold and pests, and their ability to withstand slight temperature fluctuations.


One of the best things about the legalization of cannabis has been the considerable selection of cannabis products that have become available to us. Of course, being an educated consumer means understanding products and their price points so that you can make the best decisions for your health and your wallet. So, if your dispensary offers a variety of cannabis, ask your budtender for more information on the difference between indoor, outdoor and greenhouse cannabis. You might just find a new favorite strain!
