I dont know about that one. Why would adding stress do anything thats positive this late in the game? mj produces mad amounts of thc when you give it proper air water and light not by changing one of these things into a form that would cause stress... and dry atmospheres( not dry soil! it takes water for the buds to grow duh) add trichs as its a defense mechanism so how would freezing my plants roots do anything but cause them to wilt and stress. You wait 3+ months for this plant to grow properly
