Mold on soilI used BioBizz LightMix with Monsterbud Mix from Amnesia and some mycorrhiza in the hole of the seed. 3 seeds after 3 days still not germinated in soil. Had foil on top of the pots for humidity. Probably watered a bit too much. What should I do and will my seeds still germinate?Setup. Substrates

Manure in outdoor pots.How much manure should I mix into my pro-mix. I have a pile of seasoned manure from last year and want to use it in my outdoor pots. I want to mix in some Gaia Green bloom into it also. Thinking of using 10 gallon fabric pots. My photo seedings just popped out of pure pro-mix.Setup. Substrates
