Thanks for clearing those questions up! I guess we'll keep using this thread until its moved (or if its moved) if there is a more appropriate place for it.

One additional thing.. Since you say to keep the water level about a half inch under the pots (which the roots will eventually grow into the water) what do I do about watering until they reach that point? I've noticed on Stealth Hydroponic bubbleponics systems they have a waterer/dripper system going right into the net basket.. is that necessary for all bubbleponic systems before the roots are long enough to hit the water in the bucket?
