Okay so i have my seedling started under some fluorescents right now. Papaya and blue mystic. They are around 2-4 in in height, and all are looking healthy but one. Within the next two weeks i will be transplanting to my grow area. But before then i want to add some things too the soil to make it better. My question is should i use vermiculite or peat moss or peat humus or perlite or what ever else they sell to help with aeration and drainage? Or does it even make a difference which one i use?
