You only need the airstone, you don't need to top feed at all. Look up DWC or Bubble Ponics. Cheaper and there is no water pump/lines or timers involved, just an air pump and airstones.ok so im leaning toward a top feed hydro drip system. I'm just a little confused about the air stone, is it essential and wtf is it used for?
I've heard you need it to pump air into the reservoir with the nutrients and i've also heard of using it as a grow medium.
oh VERY nice! i'm loving this setup. I just have a couple questions.You only need the airstone, you don't need to top feed at all. Look up DWC or Bubble Ponics. Cheaper and there is no water pump/lines or timers involved, just an air pump and airstones.

do you run the pump 24/7 or hook it into a timer?
and do you have to worry about the roots reaching the water or is it okay if this happens?
