I am about to start growing PKA, and I am stuck with one 250 hps for now. I have read about the hand method, but is there any other tips, or ways to judge how close to put my light at first? For example: How close should it be for seedling stage, then vegging, then flowering? I know it depends a lot on my girl's growth, but I dont want to burn my girl. I was thinking 18/6 light cycle from start to finish as well. My grow tent dimensions are 22"x36"x63". Thanks!!!!
P.S. I am only growing one plant in a 3 gallon pot. Thanks again!!!
