I'm going to be doing a small closet grow, ideally building a diy grow tent and doing the scrog method down the road and most likely 3 plants. Dimensions are tight, probably 14"x4'x4'. So far I've decided on a 24"x2 PL-55 T5 fluoros for veg, 400w dimmable hps w/ cool tube, 6" inline fan w/ carbon filter for flower. It took me about 10 days of weighing pros/cons to decide on that so now I need some help with the rest. I am not going with hydroponic just for beginner purposes, so which growing mediums do you recommend? I'd like to stay all organic as long as there is truly a purpose in doing so. Same with all nutrients and fertilizers. Just a quick run down would be awesome... for instance: -When should I start using nutrients and fertilizers? -What's the reason to use them? -Which to look for and which to stay away from? -Organic vs synthetic? -Pros/cons of various mediums? Thanks for any help
