....I teach, I preach, I tried to raise you up correctly and where do I find you? In the "plant problem" section! And with an STD no less! (silly thirp dilemma) :wtf:

I am such a perfect grower, I never have problems, (I couldn't even type that with a straight face ) so I'm not sure what you should do.

Actually the pot covers are a great idea (kissing up to Sinky) and your plantlets look big enough that damping off should not be a problem. But you want to uncover the pots daily to alow any excess moisture to escape and to check your stems anyway. As you know the d.earth will be used in place of the pot covers, so trapped moisture will not be an issue after that. Or after you erradicate the thirps. Whichever comes first.

I honestly don't know about pyrethrum spray. I'm old and the last bug killer spray I found to work was DDT, but I understand that's hard to come by these days. (that was a joke people, don't use that shit)

I'm sure someone who knows more about the pyrethrum spray will chime in.
Hope you get it under control, cause we need Horseman Rocking.
