I'm hoping to try a new grow format. The OBBT. You can see it in action here: http://icmag.com/ic/showthread.php?t=130800
Discussed in great depth Here: http://icmag.com/ic/showthread.php?t=116431
I was hooked as soon as I read about it. It all starts with The Bucket.
Here are some images from my build. 5 gallon black pails with 1/2" PVC fittings.
I tried a few different fittings, and because if the curved sides of the bucket, the Uniseals worked best. Just take care to cut a clean accurate hole with a hole saw.
These are designed to be 2/5 water and lava rock on the bottom, 3/5 grow medium on top.
I debated the overflow a lot since I didn't want the pumped air to simply escape out the overflow. To solve this, the overflow has this tail inside the bucket. This is the overflow as seen from the inside of the bucket.
EDIT: The photos show the openings covered with landscape fabric to keep the roots out. I wasn't happy with the low flow rate through the fabric, so I removed the fabric screens. Now there's there's nothing. I'm considering wire screens.
The waste valve seems like overkill, but the Uniseal really holds the PVC in place tightly. So what the heck. Works like a champ. I can screw on a garden hose to a sump pump crock for waste.
