Review on Complete DWC Hydroponics Growing System 2Pack - Medium Size Kit For The Best Indoor Herb Garden With Airstone, Bucket, And Air Pump - 15% Discount On 6 Sites - Perfect For Cilantro And Mint by Oren Perry

I like the little kit. It has a few problems that are easily remedied with more purchases, but it should arrive ready to assemble.Mine had a broken air stone. I contacted them and they said they'd replace it. A few weeks have gone by and I bought a new one. A replacement never came.The hose they give you has incorrect inner diamete for the air pump they give you. "SO what" you say? If you are able to press the tubing onto the air pump, it pops off easily and unless you check it you won't know you aren't getting bubbles in your water until plants are wilting.The check valve is not marked and the drawing is unclear. If you have it in correctly, your air will flow. If it is in backward, the pump will be on but no bubbles will flow.I have 6 heads of lettuce in mine and they look great so far!
