More bubbles=more O2 to roots= less chance of rot and more efficient nute uptake.

stinkyattic Reviewed by stinkyattic on . bubbles? I know this is a noob question but hopfully someone will help me out. I am starting ym second dwc grow first didnt go as plans. i have an elite 803 dual port air pump n it says it can have 4 air stone 2 off each. i hooked it up to my 5 gal bucks with a 6" long air "bar". Ive been told i need just enough bubbles to break the surface tention and that is pretty much all it is doing.... would switch air stone improve the over all air or will this do? Rating: 5
