well if you are talking DWC, bucket with airstone and pump, then yes it stays on 24/7. If you are growing this way keep in mind that if the air pump dies on you then you need to replace it ASAP as the plant will drown if left in water to long without air being pumped in. 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.
