help me with my dwc mini hydro!
Okay so im fairly new to hydroponics so I thought I would begin with a two 3" pot, deep water culture system for my PC grow box. Im using a small 4" inch long air stone with a 2.6 psi air pump. Im having trouble keeping the air stone in place under the net pots so it wanders around the bottom of my reservoir and doesnt airate the net pots which is a problem. My question is how can i secure the air stone to the bottom of my reservoir?
any advice is greatly appreciated.
