Greenhouses come in all shapes and sizes, and are one of the best ways to help protect your Cannabis plants from insects, harsh winds, cold weather and rain. During Summer months, a greenhouse will provide the ultimate environment to allow plants to grow into healthy, vibrant and robust plants ready to flower once Winter approaches.
With the assistance of heaters, humidifiers and dehumidifiers, it is much easier to dial in your greenhouse temperature and humidity. One good thing about plating in a greenhouse is that plants will grow big and have some serious yielding potential.
We have created a list that we believe are the very best photoperiod and autoflowering cultivars to be grown outdoors in a greenhouse. Each of the strains covered in this list will be well suited for greenhouses and will perform incredibly well in hot and cold weather.
Our team has taken the time to comprise a list of the easiest to grow, low maintenance strains that are ideal for beginner growers. This list has been created for fans of photoperiod and autoflowering, to ensure your greenhouse stays packed from Summer through to Winter, allowing multiple harvests at once.
Super Silver Haze
We kick start the list with Super Silver Haze. An Amsterdam coffeeshop favorite, made by crossing Skunk, Haze and Northern Lights genetics.
The ultimate hybrid that possesses the high resilience from its parents. She is a large yielding, heavy drinking hybrid that is quick to finish despite her sativa dominance. A solid performer that only takes 70 days to flower.
An extremely tough plant that has enormous yielding potential when trained and supported. Outdoors, Super Silver Haze can produce yields of 1200 grams (42.5 oz) per plant, under the right conditions. She will need supporting after the first few weeks of flowering, and some phenotypes may grow and stretch very tall. Tying down or topping is well advised.
Her buds have an eye watering sharp citrus, spicy and floral terpene profile. The effect is a soaring, thought inducing, cerebral roller coaster.
We like to celebrate this great hybrid by giving everyone who uses this code: KUE24KCN a free pack of Super Silver Haze! The code will be active until 2023-09-13.

Let’s grow Nirvana strains in your greenhouse
There is nothing more rewarding than watching a plant grow from seed into a vegetative stage, then produce beautiful buds. The Summer and Winter months can be much more rewarding when growing Cannabis seeds inside a greenhouse.
As long as you take extra precautions such as using a heater during cold and frosty nights, or a dehumidifier whilst plants are flowering, it is possible to grow some amazing frosty buds, with the best flavors and aromas possible!
