If you’re serious about growing cannabis you need to use a greenhouse. It’s one of the smartest moves a novice grower can make. 

Why?

Because you can provide the perfect climate year around for your buds, while guaranteeing high yield in a compact space. For example, if you’re living in a climate such as the Pacific Northwest or New England, then the outdoor weather isn’t always suitable for growing, but with a greenhouse you’re put more in control of your climate.

A greenhouse isn’t enough though. You need to have the best cannabis strains to grow in a greenhouse if you’re going to get the maximum output for your effort. 

In this article we’re going to dive deep into the top 7 strains you can grow in your greenhouse. Whether you’re a novice grower, or a seasoned vet, these strains are guaranteed to make your greenhouse growing experience a breeze.

Best Strains To Grow In A Greenhouse – Quick Look:

Why Grow Cannabis In A Greenhouse?

If you’re stuck between growing indoors and outdoors, think of a greenhouse as a happy medium. 

With a greenhouse, you’re getting the best of both the indoor and outdoor growing advantages. High quality sun (which cannabis needs to taste best for the end user) and control of the environment (which you need to ensure quality production). 

Here are a couple quick reasons to consider using a greenhouse.

Multiple Life Cycles

You can maximize the cannabis yield with a greenhouse. There’s 2 common practices which you’ll find useful. 

  1. Light Deprivation – do this during the main growing season. In the summer you’ll cut out the light to trick the plant into flowering early. 
  2. Grow During The Winter – if you’re okay with additional light sources and heaters, you can grow during winter which can produce a completely different crop.

Climate Control

If you want a quality product, you need to control the climate your plants grow in. A greenhouse provides this for you. 

By growing your plants outdoors only you leave yourself vulnerable for heavy rain, snow, and drought damage to the plants. 

Grow Rare Strains

The most advantageous part of using a greenhouse is growing rare strains! 

Most strains worth growing need a Mediteranean style climate. If you’re in the northern part of the world, you’ll never get this climate naturally.

By controlling the climate and still receiving direct sunlight, rare strains are positioned to grow optimally. 

Best Strains To Grow In Your Greenhouse For Maximum Yield

1. Gorilla Glue

One of our personal favorites. 

Gorilla glue is a joy grow, and an even better experience for the cannaseur’s in the room. 

It packs a punch with only one small toke.

Developed by GG Strains, Gorilla Glue (aka GG4) was created as the ultimate hybrid that delivers a heavy relaxation without any paranoia or anxiety.

They call it Gorilla Glue because it causes users to stick to their couch. That’s how relaxing this bud is. 

It’s easy to grow, high yield, and resistant to mold. It even won the Cannabis Cup in 2014 in Michigan and Los Angeles which should tell you it’s really good. 

The smell is next level too. It gives a very pleasant scent while tasting sour when smoked. 

After your first hit, you’ll quickly feel relaxed and happy, letting stress melt away in the background, while you melt into your couch. Many users say it’s the best body high they’ve ever had, and chronic pain users love this strain for its pain relief. If you suffer from depression, insomnia, or anxiety use this strain to help slow your mind down and relax a tense body. 

The THC levels are rather high, measuring at 28%, which means new users should be cautious. If you’re a seasoned vet, you’ll be good to go. 

Growing Gorilla Glue is noted as fairly easy for new growers. The sativa side makes the plant grow tall, and you can expect about 2.5 ounces for every square foot. 

This is our number 1 strain for new greenhouse growers. 

2. White Widow

Ahh White Widow, a legendary strain because of it’s unbelievable white trichome crystals. It literally looks like the plant has snow on it when flowering. 

White Widow is a hybrid strain which is 60% indica and 40% sativa. It originally comes from the Dutch production company “Green House Seeds” where it won the High Times Cannabis Cup in 1995. It’s taken off in popularity ever since.

White Widow contains 20% THC, beginner enthusiasts should be careful with this strain. It’s known to have a devastating kind of high because of the high THC percentage. The smell can be ammonia like, but the smoke is nice and smooth. 

Users often report a cerebral high where they become far more perceptive of their surroundings. While the plant has a higher percentage of indica, it still produces strong sativa effects where you’ll experience an uplifted mood and more energy, while feeling relaxed at the same time. It’s often recommended to smoke White Widow if you have attention disorders.  

It’s known as an easy plant for growers because it’s mold resistant, auto-flowers, and can be grown both indoors or outdoors. You need to make sure you have an almost Mediterranean climate with temperatures between 70-80 degrees for the best growing experience. 

You can expect about 2 ounces of yield per square foot of plant, although growers often say White Widow produces less yield than other strains (lower yield is typically for outdoor environment, with a greenhouse you can expect a higher yield). 

3. Northern Lights

Known as a hit and quit strain, Northern Lights is a favorite with users and growers alike. 

Northern Lights is an indica heavy strain where it’s primarily 70% indica and 30% sativa. The strain was perfected by the Dutch (they really love their indica strains) and is known as a true classic. 

It’s known to produce a body high unlike anything you’ve ever experienced. After 1 hit, you’ll instantly feel an overwhelming sense of happiness and well being, along with the overwhelming need to eat and fall asleep.

They call the strain Northern Lights because users often experience increased creativity and psychedelic(ish) experiences. If you suffer from insomnia, chronic pain, or eating disorders then you’ll love this strain. 

You’ll find Northern Lights to be the perfect beginner strain to grow. It produces a heavy and dense bud that smells musky but also sweet at the same time. It auto-flowers and needs a warm climate for optimal growing. You can expect about 250 grams of yield with a 15% THC ratio. 

4. Purple Kush

This is another pure Indica strain known for it’s amazing purple color when fully bloomed. If you have a greenhouse full of Purple Kush, you’ll think you were walking in a field of lavender. 

Originally created in California, Purple Kush is a mix between Hindu Kush from the mountains of Pakistan, and Afghani Kush. 

Purple Kush creates a very sticky resin which makes it valuable for hash or concentrates. The strain produces a medium sized bud which can be very dense for yield. It tends to create a purple color if growing in colder climates. The reason the bud gets purple is because of the breakdown in chlorophyll which happens every year in autumn with regular trees. 

When smoked the flower has a fruity taste reminiscent of a sugary grape drink. Right after the first hit you’ll feel an immediate physical relaxation with a psychedelic twist. Users often say it makes you feel slow and sleepy. It’s best used during nighttime, and is considered a helpful medication for those with depression or anxiety. 

As a grower, it’s considered a relatively easy plant to grow. Because it’s an indica strain it will grow low and heavy, with more success growing indoors due to climate control needs. You can use a vertically small greenhouse with this strain as it only grows about 3 feet high. It autoflowers within 8 weeks when grown indoors and you can expect about 30 grams per square foot.  

You’ll need to keep the greenhouse within a Mediterranean style climate with temperatures ranging from 70-80 degrees. The key to successfully growing this strain is preventing any cold temperatures from hitting the bud until right before it’s ready to harvest, where you can shock the bud to produce it’s trademark purple hues. 

5. Blue Dream

A cross between the classic Blueberry and Haze comes Blue Dream (a.k.a. Azure Haze). This sativa heavy strain is mysterious in origin, but still a favorite of enthusiasts. 

Blue Dream made its first appearance in California where it’s said to have been bred by DJ Short for the medical community. 

It has a high THC potency with it averaging in the low to mid 20% range. Because it’s primarily a sativa strain you can expect the nugs to be long, bushy, and with trippy blue hues surrounded by a lot of crispy white trichomes.

Many users say the high from Blue Dream is one of the best because it immediately motivates you and enhances focus while providing a slight body high. As the high continues to climb you’ll experience a relaxed feeling helping you mellow into a state of deep calm. It’s recommended if you suffer from chronic fatigue or depression to give Blue Dream a toke as it’s guaranteed to stimulate energy levels. 

Growing Blue Dream is relatively easy and novice growers will enjoy the process. It’s an autoflowering plant which only takes 10 weeks (if in an indoor system or greenhouse) to bloom and you can expect about 2 ounces for every square foot. It needs an indoor and mediteranian climate for optimal growing, which is why we recommend Blue Dream for your greenhouse!

6. Sour Diesel

There’s a reason they call this strain Sour Diesel. Pungent, earthy, and guaranteed to knock you on your a$$.

This sativa heavy strain has been loved by medical and recreational users for generations. It originally came from the underground scene in the early 80’s with exact origins unknown. All that matters is that the strain is probably the most notable for its gasoline-like smell (if you’re trying to be discrete about your smoking, good luck). 

The strain is roughly 60% sativa and 40% indica with a high THC content of 25% on average. It combines some of the best features of sativa and indica where you’ll get a good energy boost while feeling relaxed and mellow. 

Enthusiasts often say the taste is very unpleasant, but the high is unbelievable. Upon the first hit you’ll feel an immediate head rush and greater energy levels. It’s common to get a cerebral or spacey feeling too. Fans love this strain for help with creativity and depression because while Sour Diesel has a good deal of indica in it, you won’t experience any couchlock. Be careful not to use this strain if you have anxiety or paranoia because it’s a common side effect. 

Growing Sour Diesel is a lot of fun, although your greenhouse will smell like a gas station. It’s rated as an easy difficulty for growing and it needs an indoor climate in the 70-80 degree range with medium humidity. Sour Diesel is mold resistant, grows compactly even for a sativa plant, and flowers very quickly with an 8 week period. You can easily expect about 2 ounces for every square foot of plant. 

7. Lambs Breath

Known for being Bob Marley’s favorite strain, Lambs Breath boasts an energetic high full of creativity and focus. 

The origins of Lambs Breath comes from Jamaica where it grew wild and free in the hot tropical climate. The strain has grown massively in popularity over the years, but it’s rather difficult to find in North America. 

Lambs Breath is nearly all sativa with it being 85% sativa and 15% indica and rocks a very potent THC percentage of 19%. It’s called Lambs Breath because it has a skunky, yet cheesy, smell that can be very potent at first. However, smoking is a completely different story. Users often say it’s a creamy and sweet smoke which is enjoyable to inhale. Nothing like the first whiff. 

The high is very cerebral and is noted for making enthusiasts feel almost excited from the first hit. In fact, users often say it’s the best mood boost they’ve ever experienced. You’ll get a sense of euphoria and creativity that can help you break through any writers block. It’s often recommended those with depression try this strain out because of the uplifting feeling. 

Growing this strain is easy and recommended for beginners with a greenhouse. It only takes 8 weeks for it to flower making it perfect for indoor or greenhouse cultivation. You can expect about 2 ounces for every square foot of plant. Great for those looking for high yield strains!
