I have a homemade DWC system, made out of the blue storage totes. It has 6 plants in it. 4, 5inch Airstones, and 4 12inch airstone strips, which are all connected to a high output airpump. Also there is a water pump inside the tote to circulate the water. I have 2 of these, so 12 plants total. I have not added ANY nutes to the water yet, the PH is 5.5-6.0, and ive been adding the correct amounts of H202. I started 12 seeds last monday, so 10 days ago. I started them out in paper towels and moved them to "rapid rooter" spongers on wednesday(8 days ago) and I put them in the DWC setup. Since then the plants have grown, but not anywhere near as fast as a soil plant would have. They just now are getting their first 2 actual leaves. Could I being something wrong? Im considering going back to soil, this is my first time with DWC and its not working half as good as my soil plants were. Any advice would help. If you have any, please comment. Thanks.
