Well, you can make your own "waterfarm" bucket using stuff you probably got at home or is no farther away than your local hardware store.. I used the round 5 gallon buckets from Home Depot and made my waterfarm hardware using half inch CPVC pipe. see attached pics.

Anyway, it consists of a 12" cpvc pipe with a hole drilled near the bottom of the pipe that will facilitate a 1/4" tube that goes directly up out of the water.
So the pipe with the tubing end goes straight down near the bottom of the bucket. Then, hook the air pump up to the other end of the tube. You are basically pushing the air along inside the tube and it exits INSIDE the tube very near the bottom of the bucket. The air is pushed Down, and thereby bringing the water up out of the foot long pipe. From there on, its just a matter of putting an elbow on the top and leading the water coming up towards the middle of the bucket where you want the water to go. I use another CPVC pipe maybe 3" long add a tee, and then put a couple of 45s on each end, and have 3 places that the water pumps out to. You can also drill a couple of small holes in the pipe to release some of the nutes on the way out of the 45s.

Judging by my progressively better grows, you folks know your horticulture. Many thanks. So here is the jist of my setup.
