    Large DWCvs RDWC

    i have an indoor pond that I plan to convert to a large dwc and use it to flower my plants. Not to knock on anyones designs but this way seems a lot simplier than building a RDWC. Im worried im over looking something huge that makes this idea no good. Can anyone see a flaw with this?
