Seeds cracked and started after 12 hours in water and kelp solution. Germination stopped when moved to the paper towel, so after 3 days I moved them to soil before they rotted. The seeds seem ok, but the "new" soil has some bugs. I see some gnats, and some spiders that are not mites. Just spiders. Should I put in some diatomaceous earth, or see if the spiders eat the gnats?
