how much do you fill the res for dwc? I've been filling it almost to the bottom of net pot with very little roots hanging but lots of bubbles. Should I only fill like halfway to make roots grow? they're big plants with established roots

1-3" between pot bottom and top of water...on average, but there needs to be a gap.
Usually works as bubbles break they water...then roots search for water and drop...as long a hydroton is wet you should be fine.

1st you said very little roots hanging, now your last post says no root rot nice big rootball. Make up your mind. Nice big plants and large rootball? If that is true obviously what you are doing is working. Flip the dam light or keep playing games?

LOL...well back to the distance...
I'd slowly decrease and wait a few days between...if things look bad then go back.Also maybe less chance of shocking them much.

If your roots don't have to "reach" for the water then they will take forever to bust out of the pot. I find that about 2 inches is the magic number. It depends on your setup though, if you run air stones and the pump is really strong you may have to go a bit lower since the bubbles busting on the surface will mist the bottom of the net pot too much, you want it barely misted.

Ya I think this was the problem. I have one of the big metal pumps with 8 outlets and produces lots of air but I was filling almost to the net pot

Those pumps move a lot of air but they also heat it considerably thus warming the water. Not ideal but if you have a chiller you can fight it.

Air stones can also cause your pH to drop because the Co2 in the air created carbonic acid. You might look into a waterfall setup for oxygenation.

Fore the same level of oxygenation with a waterfall or an air stone would you not get the same amount of CO2 dissolved in the water? If you are picking up too much CO2 wouldn't reduce the air going into the air stone do the same thing?

I will say this. The lower you run your water level, the thicker the feeder roots leading to the main rootball will be. Seems if you run it higher, you will get more root mass, rather than having long thick feeder roots leading to it.
