Best Cannabis Strains To Grow In A Greenhouse

Ganja For The Greenhouse — Five Great Weed Strains For Greenhouse Growers

Greenhouses offer cannabis cultivators the best of outdoor and indoor growing. You'll enjoy the sun's rays during the day without worrying about hazards like rainstorms, snow, or excessive wind. Greenhouses also preserve your cannabis plants from countless outdoor pests that are all too eager to destroy your favorite strains. 

Five Fantastic Strains For Greenhouses

While pretty much any cannabis strain does great in a greenhouse, there are a few standout options. The five strains below each have unique issues that make them better suited for a greenhouse rather than a outdoor grow. 

Amnesia Haze

Winner of High Times' "Best Sativa" in 2012, Amnesia Haze is one doozy of a strain from the "Dutch masters" at Soma Seeds. This 80/20 sativa-dominant strain has traces of multiple landraces, including Jamaican, Laotian, and Afghani. 

Given its sativa bias and 20-plus-percent THC content, this hybrid is an excellent choice for a near-psychedelic daytime smoke. People with a high THC tolerance will probably notice extreme euphoria, giggles, and creativity after one hit of high-quality Amnesia Haze. The citrusy and hashy terpenes complement Amnesia Haze's energizing properties.

Despite the heavy traces of landraces, Amnesia Haze is one of the more difficult strains to cultivate outdoors due to its low resistance to pests. However, since many of Amnesia Haze's parents evolved in different regions, this strain loves sunlight. Greenhouses provide the pest-protection Amnesia Haze needs plus the natural light it craves. 

Generally, it takes between 10 - 13 weeks for Amnesia Haze to reach its max height of about 140 cm. Taking proper care of this finicky strain could reward you with upwards of 500 g per plant. 

AK-47

AK-47 shares a similar backstory to Amnesia Haze. This hybrid first emerged at an Amsterdam seed bank, has a sativa dominance, and contains genes from multiple weed landraces. Most reports suggest AK-47 has small amounts of Columbian, Mexican, Thai, and Afghani strains. These genes usually give AK-47 a 65/35 sativa-to-indica ratio. 

Even though AK-47 is technically a sativa, many people report that its average growth rate and effects are more in line with an indica. The ~ 20 percent THC content will probably give you a cerebral buzz, but the effects aren't as energizing as full sativa hybrids. 

Many people notice AK-47's effects morph into a gentle "body buzz" after a few minutes. This relaxed-yet-alert sensation is ideal for situations where you want to chill and remain alert. For instance, many people use AK-47 during mellow parties or while binging on Netflix. 

As for flavors, AK-47 has a pronounced earthy profile with high traces of the terpene alpha-pinene. However, smokers also detect notes of citrus, spice, and hash as they smoke or vape this strain.

Although many of AK-47's parents grew outdoors, this strain isn't well-suited for an open-air garden. Chances are far greater that AK-47 will develop but rot or fungus if left outdoors. This makes AK-47 an excellent option for people with access to a controlled greenhouse-growing environment. 

Most reports suggest AK-47 grows to a height of 80 - 140 cm and yields about 300 g per plant. You should expect to harvest AK-47 seeds at about 9 - 10 weeks into gardening. 

Blue Dream

Many assume the "dream" in Blue Dream's name refers to its slumber-inducing effects. However, it's more likely Blue Dream's breeders gave it this name due to its reliable indoor growth pattern. Although this strain is slightly susceptible to outdoor pests, it doesn't have many issues in greenhouse settings. This strain's relatively easy growth pattern and well-balanced high make it an attractive choice for new tokers. 

First introduced in California, Blue Dream is a 65/35 sativa-to-indica mix of Blueberry and Haze strains. The fusion of these legendary strains gives Blue Dream a blend of euphoric and relaxing effects. The THC content can reach above 20 percent in this strain, but Blue Dream often has noteworthy CBD rates of around 2 percent. CBD helps dampen THC's psychoactivity, thus reducing the odds Blue Dream will provoke paranoia. 

Blue Dream also has a delectable flavor profile that leans heavily on the fruity side. The aromas of fresh berries and sugar will be "in-your-face" at flowering time, but there are also heavy traces of spice and pine. 

On average, it takes about 9 - 10 weeks for Blue Dream to reach the flowering stage and a height of 300 cm. Greenhouse growers could harvest as much as 450 g per plant if they train Blue Dream properly with LST, ScrOG, or topping. 

Green Crack

Famous for its connection to rapper Snoop Dogg, Greek Crack is one of North America's most energizing buds. THC levels in this "bad boy" top out around 25 percent, and there's virtually zero CBD. Even though sativa dominance clocks in at about 65 percent, Green Crack will deliver extreme euphoric effects from the get-go. 

Green Crack is one strain newbies shouldn't mess around with. The energizing effects from Green Crack can induce an intense head buzz high that could make you dizzy and disoriented. Be sure you have a strong THC tolerance before adding these citrusy nugs to your joint. 

While Green Crack has strong effects, it's not super resilient outdoors. In fact, many outdoor growers complain that Green Crack is very susceptible to mold. This makes Green Crack seeds an optimal choice for a well-ventilated greenhouse setting. With proper care, Green Crack will reach heights of about 125 cm within 9 - 10 weeks. Generally, growers yield about 300 g per Green Crack plant. 

Gorilla Glue #4

Gorilla Glue #4 (aka "Original Glue") is a great greenhouse strain for growers who want dense couchlock nugs. This mix of Chem's Sister, Sour Dubb, and Chocolate Diesel has a 60 percent indica dominance and THC that's typically well above 21 percent. 

While this strain may have the gassy & industrial notes of Sour Diesel, it doesn't have the latter strain's sativa-heavy effects. True to its name, GG4 will "glue" you to your sofa after a few puffs. This makes GG4 an excellent option for those interested in dozing off after a stressful day. 

One of the issues with growing GG4 outdoors is that it doesn't do well with environmental stress. Indeed, one common complaint associated with growing GG4 is that it has a higher-than-average rate of "herming out." In other words, feminized GG4 often turns into hermaphrodite plants. Since hermaphrodite weed won't produce cannabinoid-rich nugs, they will ruin your entire grow operation. 

Thankfully, you can lower the risk of GG4 "herming out" by growing it in a stress-free greenhouse environment. Since you can control the temperature and ventilation in your greenhouse, it's easier to avoid putting your GG4 under too much stress.

Gorilla Glue #4 typically grows to a max height of 190 cm within about 10 weeks. You could harvest as much as 500 g per GG4 plant with basic training techniques like LST. 

Give Your Ganja The Greatest Greenhouse Set-Up

Sometimes, you could "set" your greenhouse's temps, humidity, and watering system and "forget it." While you may get decent results with this passive gardening method, it's always better to carefully research the specifics of whatever strain you're interested in. The more you can adjust your indoor settings to your strain's preferences, the greater odds you'll bring home boatloads of buds.
