You guys really think you should kill the top feed after your roots hit the water. I'm wondering on how much roots you would want in the bottom bucket before you killed the top feed? I don't really see why if your running straight hydroton and maybe with a small 3 inch coco pot in the large 10 inch net pots why running a top feed would do any damage. As long as it drains really well as in no standing water whats the problem with the top feed. I'm only saying this as if you cut off the top feed won't the roots up top dry out? I can see a few of my roots on the sides that for some reason the water stopped running to and they dried out so wouldn't this happen to the roots in top of the baskets also. Just don't want to stress the plants any. Also since I started using Hydrofungicide I haven't had any more issues so far at least with gnats. I just use it when I flush. I'll let everyone know how it goes this round for me as my first mpb had problems but fingers crossed this one look good.

Your looking at it the wrong way.. Ask your self what it does for you and the answer is nothing after the roots hit the water. If you do use it you have to worry about rot.
LOST makes sense on this issue. I never could account for the differences between the advice of 24/7 dripper and not allowing rockwool to get waterlogged.
If the difference is to have the drip on the outside where it doesn't run through the rockwool, I would nix the drip. In fact I just turned mine off.
Perhaps a 20 min. drip 2-3 times during a light cycle...but 24/7 seems risky for any possible benefits.
