If you cook your soil it will kill all that shit you just have to add your bennies back inThe diesel berry is pretty tough, my soil eats most of my seeds, I got one strong diesel berry sprout shining through, it's the first of 3 strains to jump to it.
I'm working on my seed starting ritual of sorts, made specific seed starting soil and I'm going to see what i can do to get all my seeds to survive future attempt.
I thought I had mixed the perfect balanced soil that the seedlings could handle but we lost seeds to; nematodes, spring tails, centipedes, soil mites and possibly other micro organisms in my soil. My recycled soil is just too wild.
Seed starting: peatmoss and perlite neutral soil, add worm castings and vermiculite, dish out into small cups.
