BigWeed Reviewed by BigWeed on . Rubbermaid DWC Hows things people? Got a question regarding a rubbermaid DWC system. I got some good advice about creating one. I just wanted to run it by everyone and see if you think it will be good. 18 gal rubbermaid container, cutting two 3" holes in the lid for the net pots filled with hydroton, and having the seedling in a small rockwool cube. 1 aquarium airpump going thru a 12" airstone.
