I guess I deleted most of my older pics but these 2 will make the point. Bucket, netpot, water, nutes, airstone, pump, plant and a lil Tron and thats all it takes. All can be purchased at Lowes, Walmart and Home dePOT, not to mention others, minus the Tron, nutes and plant. 1st pic is showing 5 seperate plants in their own lil bucket, no I have not be endorsed by Lowes for advertising. 2nd pic shows 1 of the pumps in background.

With the DWC how often do you change the water in the buckets? How do you change water when you start to get a big root ball?
