I ran some air through it today, and the bubbles are still pretty big, so i might seal up those holes and drill a hole for a 2" air stone underneath each pot. I bought 6 air stones today so I will probably do that, and ill leave the holes in the very middle that won't directly hit the roots.

.....I went a little overboard on the air pump and got this 1,000 GPH pump...

khazoth Reviewed by khazoth on . Six Plant Rubbermaid DWC Hello everyone, I currently have a 3ft X 2ft X 6in tray that I use for ebb and flow with a 14 gallon reservoir underneath it. I built the system with rubbermaid containers, and did not put much consideration into complete drainage. The fill/drain fittings are right in the middle, causing a small layer of water to remain for most of the day, every day. In the future i will place the fittings on one end of the tray, and have the other end slightly elevated, to force all water to drain to one Rating: 5
