This is a small ebb and flow that I made for the 32" x 32" tent that I have. I pretty much went from the DIYs that are here and used what I had. Thanks! Fortunately, I had everything I needed, but was short on medium. I decided to add an air pump and air stones to the res. The parts I used on this unit were:
18" x 18" x 6" tray
10 gal tote
160 gph water pump and plastic tubing
Dual outlet air pump, air stones, and plastic tubing
This great THG. I'm contemplating turning one of my 2 grow closets into a Flood & Drain setup.
I have a question. What is the value in aerating the nute solution in the reservoir? I was hoping the draining process itself would sufficiently draw in air (oxygen) so as to eliminate the need to oxygenate the nutrient solution in the reservoir.
DWC demands the inclusion of oxygenating the reservoir. But Flood & Drain? Why?
I'm just wondering. Not interrogating. Thanks.
