I put hose bibs on the bottom end of the tank or buckets. Hook a piece of garden hose on it and run bout 2 ft to the sump pump. Turn the dial and 20 gal drains in bout 3-5 mins. Since I am doing 5 gal buckets this time around then skeets process sounds most efficient to me. One extra bucket is all you need, replace one plant into new bucket, clean the old one then put next plant in it while you clean next one....and so on. Even though buckets only have a few gallons in them, I will still put a ball valve on to drain the water first, then switch and clean. I will be posting parts and pics prob tonight as I put them together.
cannakeeper Reviewed by cannakeeper on . how to change water in DWC Since I am new at this whole water thing.... How do I change my DWC water "resevoir"? Do I just take the lid off, hold up the plants and roots, dump and refill? Do I use a second tub and do a switch placing the old lid on the new tub? What do you do and how do you change your resevoir and how often? Rating: 5
