DWC -plants wilt during day, fine at night??

[Maitreyah]

I have not started my DWC grow yet. However, a thought occured to me.

Where is your air pump located?

Is it inside the grow room?

If so, you are pumping the CO2 straight to your roots when your CO2 is on. Your air pump needs to be outside of the grow room since you are running CO2.

The roots need oxygen, the tops need CO2.

Hope this doesn't offend you. Just a thought. Sometimes it is the SIMPLE things that get ya.

My air pump is located outside the building bringing in fresh air.
I have somewhat figured out the problem which was my water temps where a bit too high in the buckets and starving the plants of oxygen. I lowered the temp on my water chiller about five degrees which made it ok for the water to warm up abit while traveling in the room.

Garden of dreams has the right idea, If you can do that youl be all good. Don't panic I've learned there is room for error in this system and a good h2o2 flush will solve most problems

HYGROZYME, I too had the slime, I think that stuff is for drain to waste. I replaced it with house and garden's enzyme and I've been all good.
