DWC Feed pump on with lights off?

[SurfBuddy]

I know I read about it but now I can't find where in the threads...

Is it good practice to turn off the water/feed pump during lights out? Roots are still reaching for the res.

TIA,

I always leave the pump on 24/7.

Thanks PP, I was worried about overwatering, but I guess eventually they will all be sitting in the water, eh?

personally, i dont use a feed pump. just air stones.

typically, when the bubbles pop, they provide enough moisture for the roots. everyone has different opinions on it. but, IMO, you're fine to shut it off forever... so at night shouldnt be a problem

I've actually got bubblers in both reservoirs... the guy at the hydro shop said I only need it in the big res (not where the plants sit), but I liked the idea of the bubbles close to the plants too, so I have 4 in the big and 2 in the plant res.

I guess I could disconnect it from 1/2 of each strain to see what happens...

as long as you have a good amount of bubbles being produced in the res your plant sits in, you dont need the top drip. but, if you have the aeration of the water taking place in a different res, then yes, you need top drip.

Got it, thanks!

Not all of us do i that way. I leave the pump in until I have a rather large mass of roots down into the reservoir.
