they suck..i lost 10 seedlings also..think they were in my worm castings cause i got my soil straight..then i added new castings and the trouble began.
Ouch! Ten seedlings? That's a massacre. That's like $100 worth of seeds, jeeze mun that's brutal. I lost 3 or 4 a few months back... I went with straight promix afterwards aswell, I guess buds love poop.
