if your new u should try and look what type of set up your looking to go with. DWC, ebb and flow or ebb and grow, or the dripper. i have dwc and ebb and flow and i think the ebb and flow is way eazyer because i only have to change water once a week. the dwc i gotta top it everyday because the water evaporate fast from the 1k light. if u build one it will save u way more money and u will learn and understand how it work. i build one for 20 dollar and it hold 6, 5inch circle net pot. so can u. :rasta:
