Yes, but I mean in regards to keeping the air gap temperature at around 74f, in addition to raising the water level.I mean you can't mist to much but I'd say like 5 sec every 15 min is plenty... not like it's exposed to low humidity.
I think I'll place a permanent temperature sensor in the problematic area and will conduct some experiments.
To conclude, IMO the DWC air gap temperature subject is underrated in its importance.
I bet that countless DWC grows failed due to high air temperature in the root zone area.
Growers will try the craziest stuff, including spending an astonishing amount of money, without identifying the real culprit.
Not many talks about it tho, it's like the problem isn't defined enough to be adequately discussed.
