Best Cannabis Strains for Greenhouse Growing

Greenhouse growing is the closest thing to having the best of both worlds. Natural sunlight does the heavy lifting while the structure extends your season by four to eight weeks compared to open outdoor growing and protects plants from the weather variability that costs outdoor growers harvests every year. The best greenhouse strains take full advantage of that extended timeline to develop larger structures and heavier final weights than traditional outdoor grows allow. They have also been selected specifically for mold resistance, because greenhouse humidity in late flowering can be difficult to manage and genetics that cannot handle it will cost you. The strains here are validated by community greenhouse growers with documented results in both amateur home greenhouse setups and more managed facilities.
