Im looking for advice on how to improve my dwc setup. im currently growing inside in a pvc frame tarp covered "tent". I have a rubbermaid tub with a styrofoam board just floating on the water with 2 holes in it (only 1 used now due to inexperience). I have a medium sized airstone and a decent pump. Lights atm (flowering) are 3000k T8 flouro tubes hanging just a few inches above the plant for vegg i use a few 5600k CFLs. I began with miricale grow multi perp and then bloom booster. everything is working well now i have had a few problems but nothing really severe, i will try to load pics at a later time. Im not looking for real expensive upgrades, just things that i need to change or correct. i know i should use some organic ferts and HPS lights and stuff but i dont have money for that. thanks for looking guys
