I used 4 cups peat, one cup black cow, one cup mushroom compost, and one cup perlite for my seed starting mix on my first tray and second tray. but i must admit that i did water with mist on top alot and bottom a few times since my heat mat was drying up everyting even with my dome on.
Making all my moisture turning into condensation so i had to keep my soil atleast moist.
Then my third tray which i just started two days ago was only peat and perlite and only was bottom watered. in addition i will have not used my heat mat since these problems have been happening, same with my domes
Plus I read that cinnamon helps deter fungus/ damping off so i have been covering all the cell tray tops with it.
first tray is a month old or more
second tray is 2/3 weeks
third tray is 3 days
Any help/suggestion will be greatly appreciated, Thank you all
