What water level do you refill your dwc reservoir?

2/3 to 3/4 of the bucket. i try and avoid the water level going below 1/2.

I fill to the bottom of the basket, and make sure I refill before any airstones might start to come out of the water. I use the 2x4 coke can stones so I usually make sure I keep 5 or 6 inches of water in the bottom of res at minimum.

2-3 inches below bottom of net pot. I top up a gallon a day I dont let it get more than 2 gal low

I start off with an inch below the net pots. As the roots start dropping, I adjust the water to a lower level for more O2 - within reason. You don't want dehydrated root mass. Someday I will probably be doing aeroponics.

Then I have a secondary reservoir outside of the tent with a submersible pump - it helps keep the roots cool and keeps more O2 in the water - I prefer to have a container size double the total volume of water in my grow - I fill it to a safe level and pump to the buckets. That helps manage risk of overflow and the larger volume helps reduce temps from the pump.

i start with the jiffy cube just touching the water soo when i turn on air pump bubles water it. i keep it there until flower then later half of the grow i go 1/2 of the bucket i read somewhere it would make her think drought will come soo she starts producing resin to lower evaporation. she drinks the same amount of water soo dont beleve i am losing anything.i guess i get more air roots

I start like most other do. When they are seedlings, ill have my water level just touching the bottom of the net. When the roots protrude the net, i then will let my water level drop to about 1" below the net, and will keep it there until she finishes. If I'm running a DWC ill top off as needed. Same with my RDWC set up, just not as frequent.
