I've got a tray of sundew seedlings of a number of different species. For the past week or so, this whitish mold has been spreading across the top of the substrate. The soil mix is a 1:1 peat and sand mix. I'm not sure what sort of anti fungal treatments would be safe for the seedlings.

get plenty of airflow on it. Good airflow will stop white mold getting a hold

There are some other options as well. Dilute H2O2, cinnamon, and Bioadvance 3 in 1 all seem to be safe for plants

If it's that light gray, wispy fuzz, that's nothing to worry about as long as it doesn't overwhelm the seedlings. Increased airflow is probably the easiest remedy, but you can try decreasing the moisture as well. Watch them if you do that because seedlings will go down fast.
If you use an anti fungal, go light. Drosera are less forgiving with chemicals, seedlings more so.

Everything happens for a reason. Sometimes the reason is that I make bad decisions.

I already had the lid off, so I drained the water that was in there and hit it with some diluted H2O2. Hopefully that helps, thanks all!
