Thanks for all the comments. Can Pinguicula Man weigh in? The sethos I have is from him is in pure peat per his recommendation and its the only mex ping I have that is flourishing. So far the seedlings I have are doing OK.
Tamlin, my light is hung from the beams in my basement and I locate my plants around the grow room based on thier lighting requirements. The sun lovers are under the light on the basement floor approx. 5 feet from the light.
