Greenhouses are a cannabis grower’s best friend. These trusty structures combine the high degree of control allotted by indoor growing with the sun exposure of the great outdoors. This allows growers to extend the growing season, which becomes especially helpful in colder climates. With the addition of a few lights, one can even raise plants all year round in regions with mild winters.

These glass or metal shells also protect cannabis plants from branch-snapping winds and mouldy flowers caused by excessive downpours. The microclimate they create also makes for more consistent buds, healthier plants, and bigger bounties. Finally, marijuana greenhouses make growing outside more stealthy, especially as they help to contain the obvious aroma and sight of the plants.

Most cannabis strains thrive in greenhouses. However, several are uniquely suited to this environment, really capitalising on the extended growing season and other benefits these structures provide. If you plan on filling your marijuana greenhouse anytime soon, you need to get to know these varieties.

Shining Silver Haze

Shining Silver Haze comes into her own within the confines of a greenhouse. This hard-hitting sativa packs a heavy punch with 21% THC. However, medium quantities of CBD offer a grounding effect. As the descendant of Haze, Skunk, and Northern Light, this cultivar imparts an energising cerebral high that will wake you up in the morning. When grown in a greenhouse, you can expect excellent yields of up to 650g/plant. However, she can grow up to 220cm tall, so you’ll either need a high roof or experience in training plants. Prepare to harvest your crop during late October.

Amnesia Haze

Just like the above, Amnesia Haze requires a long growing season, which makes her the perfect candidate for cultivating in a greenhouse. This superstar stems from Original Amnesia Haze and features a sativa-dominant genetic profile. Pair this trait with a THC level of 22%, and you’re in for a lively and motivating high. This tall strain produces long colas and peaks at a height of 210cm, although you can keep her at around 175cm using various training techniques. Expect a massive return of up to 700g/plant, ready to harvest in late October.

Shogun

Shogun is one of the best strains to grow in a greenhouse, as she offers both a rewarding cultivation experience and a rewarding high. She goes to war, nobly, against negative emotions and low moods. This uplifting sativa wields a THC content of 25%, slashing away feelings of lethargy and leaving you ready to tackle the day ahead. Her gorgeous flowers also add some serious colour to your greenhouse, including shades of dark green and hints of purple. With a peak height of 190cm, some growers might find themselves in need of a box to defoliate the upper canopy. This strain relies on long summers to grow, making greenhouses a must for cultivators further north. Be prepared to harvest, dry, and cure 650–750g/plant.

Mimosa

Talk about delicious; Mimosa packs moreish tastes of citrus and earth that will leave you awake and refreshed. Sure, she makes for a great smoke, but vaping these flowers enables her terpenes to really come to the fore. Although sativa dominant in nature, this strain peaks at a height of 100cm, making her an ideal choice for those with small greenhouses. But don’t let her size fool you, yields of 550g/plant are no joke. Following harvest and processing, you’ll enjoy thick colas packed with 23% THC.

Chocolate Haze

Beware. This strain might cause some growers to mistake their greenhouse for Willy Wonka’s warehouse. The chocolatey, earthy, and fruity terpene profile of Chocolate Haze will take you to a different place. She tastes unlike anything else out there. However, you need to exercise patience to earn these buds. She yields up to 500g/plant, but won’t fully mature until late October. But after a good dry and cure, Chocolate Haze is all yours to experience. As her flavours begin to fade from your tongue, you’ll feel an intense sativa buzz begin to take hold.

Diesel Automatic

Grow Diesel Automatic in your autoflower greenhouse if you’re looking for something more subtle in effect. If you prefer to tickle your receptors with THC, as opposed to absolutely hammering them, then a content of 14% will fit the bill. Many growers reserve greenhouses for photoperiod sativas, but they work just as great with autos. Because they grow so quickly, you can achieve several harvests in a single season. You can expect to rake in up to 110g/plant in as little as 13 weeks. Terpenes bearing notes of fruit, citrus, and diesel will reward you for your effort.
