where do you get those grow chambers??

[pdp]

And Lowed sells PVC fence posts that are just under 5"x5"x100" cost is about 20 bucks plus the gule (5 bucks a tube) and end caps (4 bucks each). They are perfect for 3 3/4" net pots and growing SOG or even screen of green method. You can use bar sink traps as the drain too. Very easy to install.

HD around here needs to special order that size PVC post but Lowes stocks it.

thanks guys
i will look into the fence posts
also, can anyone elaborate on the draining method?
i was going to just have one end sit on the reservoir with a hole cut on the bottom and the other end tilted up a little
that way the excess nutes would just leak back into the reservoir
seems like the easiest and cheapest way to drain
want to move on up and give aero a try
