Ok, here I am 2 months into a grow and plants are 40inches tall. the problem is I havent cut the lights back yet... I am finally ready to do so but I only have 8inches of grow height left. I know I have to top them, this would be the second time, but how much should I take off and how long should I wait after to cut lights?
any help would be appreciated....thanks Jtime
