I looked in at the bubbles, seemed like like when I turned air pump down to 75%, there were more bubbles went across the surface. on full power seems bubbles just pop at surface in center of bucket.
which is better.
More small bubbles is better than less big bubbles. If that makes sense... it's the popping of the bubble at the top of res that oxygenates the water. Whether it occurs in the middle or the edges is inconsequential.
Well the dwc was not working for me. plants were dying. I moved to a different grow media. coco perlite. I just could not let them die. the other two babies just got into cups today.
Need help.
