About 2 months ago, I made 3 compots from a flask of Phrag sargentianum from Woodstream. They have been doing quite well so far, all still alive, and pretty much all have put out 2-3 new leaves since being deflasked. There was one compot that was yellowing a bit out of flask, but I have a feeling that it was a density/humidity issue. I had an odd number of seedlings, so that one had 3 while the other two pots had 5 each. They perked up a bit when I added some live moss to the pots. Lately, I have been battling mold growing on the surface. It's not from leftover agar (I carefully blasted away all of the agar and separated out the clump of seedlings). Nor is it really harming the plants, but I would rather not have it choke out the moss. Any thoughts or techniques for how to suppress mold growth in compots, (preferably without harming the moss)? I know that is a tall order, but I figure it can't hurt to ask. I suspect it is probably because the humidity is really high around these guys and the temps are a bit cool right now.
