I used it for one cycle. stopped using it cuz i had to move and couldn't fit it into the new grow space. Ended up just doing fill and drain. Its a awesome system shortens flowering time by bout a week and a half. Keep the PH in check and keeps the nutrient mixture. Mixed so there no settlement to the bottom. If your interested i can cut you a great deal on it. Everything included that came with it. Cups/pump/trays/rez
