John, watch out for that green slime, it can be devastating to seeds and
seedlings and will swallow pygmy Drosera whole. I know someone who
went on vacation for a week and when she came back the surfaces of
her seedling pots were covered with about a half-inch of the slime, she
lost everything (the guy watering her trays for her was not a plant person
so he had no idea what was happening). My own colony of D. pygmaea
was hit by it, it smothered a couple, one recovered, the other didn't.
I solved the problem by keeping the pot on the dry side for awhile, wiping
as much of the slime as I could off the surface, and putting a layer of
sand over the old soil, that all managed to dry it up. This slime really
moves fast, had I not noticed it when I did it would have covered the whole
surface of the pot in no time. For bigger plants it's more of a nuisance
than a life threatener, but keep your eye on it.
Regards,
Demetrios
