verry new at this !!

ive seen friends grow ops good and bad ones and ive recently started my own small one .. i set up the natural 50/50 cow manure and compost i bought at wally world. i am also experminting with the 5 gal bucket homemade dwc hydro system. i am wondering the amounts of nutrients and the what to look out for for both systems. i havent started the dwc growing yet but hope to be within another week or so.
so anybody with tips or there own proven way the help would be greatly appreciated

stay up there ppl :P

ps it is a closet op but plenty tall and no more than a few plants approx 3x3
