Very nice. Just wondering how much noise does the bubbling action make or the pump? Also what's the diameter and vertical specs on your containers? Thinking about doing a DWC sog with northern lights or another heavy indica sqeezing as many buckets as possible in a 24"wide 48"lenth and 8+foot ceiling closet under 1 600w with short veg time. But stealth is a concern that's why I'm slightly leaning to a ebb and flow setup because I imagine running 12+ airstones must give off some considerable noise. But on the other hand DWC seems to provide more explosive growth than ebb and flow.
