I would recommend staying away from peat. Its very acdic, and can hold way to much water leading to dampening off. Also, there is a netting that goes arond the pellet to hold it together that is suprisingly tough for lil mj roots to break through.

Stay with just some seedling starter soil in some 6 pack seed starting containers. Stay away from MG and other soils that come prefertalized. Good luck!
