Planted all 4 seeds into solo cups of KIS organic soil blend. Only soaked seeds for 8hrs. Made a DIY seedling box which is helping keep humidity up 75%+. 2 100watt CFL 6500k sitting on top about 8 inches above.
Just a thought, but you might be overthinking this entire process. The white "mold" on your soil surface is likely a friendly soil fungus, and could be working with your compost teas and microbes in the soil breaking down all those nutrients into plant available forms. Happy Growing.
