haha... wow

thats a root ball there!!!!!!!....lol

i have had that problem also....... but be aware of that stone clogging up.. thats what happend to me......

my plants leaves started to wilt on the tips and i thought it had a nute dyfencey but i lifted the bucket to check tds and ph i found that very very little air was getting out of the stone (not even enough to bubble)

what i did (which i would NOT advise you to do) is i disconnected my air line from the pump and hooked my 225 psi. compressor on it and blew 25 psi into it for about 5 minutes, and that fixed me up (so far)

and the plant seemed to enjoy all that air

anyways keep us updated.....

ps. i have to agree with latewood on that 3rd pic.... =)
