well the only thing i would say thats bad about this is that moving soil to a DWC because the soil will eventually break down in the system and can clog any water pumps and get your DWC dirty, thats why alot of people use rockwool cubes for DWC. and as long as you have that cabon filter attached to that air duct that is blowing out your window they wont smell a thing.Okay because I have to be inconspicuous here... my window is like 40 feet from my neighbors house, he won't be able to smell anything if I am running that duct out the window? Okay well I guess I need to go buy my stuff to build my DWC... because I germinated the girls and put it in a net pot with miraclegro and now I want to move it to DWC.. I wonder if that is bad?
