Hello, I know there are tons of threads about DSM HC. I've looked at countless threads but can't seem to get an answer for my particular scenario. I started a DSM in my 12g long. I've done a DSM with HC and EWC before and had outstanding results.

The problem I'm having is if I mist too much I get the white cottony mold/fungus (not sure what it is exactly). It seems like if I mist too little the plants dry up and most of them seem to be dying off. I've tried 100% covered, no cover, and almost every other way imaginable. I went ahead and ordered another tissue culture to restart. I plan on doing a short DSM with the new plants as I do have a Co2 system and have read that DSM is sort of pointless with unlimited Co2 access. But I want to avoid mold/fungus and the drying up for the first week while the plants get rooted. What am I doing wrong? I tried H202 and that seemed to kill the cottony invader, but I really slowed down on misting water to avoid it.
