i have 2 seedlings in organic potting soil under cfls in a decent size grow cabinet about 3 inches from the plant itself. i get alot of sunlight through a near by window would it be good to set them there for a few hours a day to get some extra light they will be under a 150w hps in a wekk or so.also if you have any pointers they might be helpful in this stage of growth that would be great thank you>
