its a no no on that miracle grow, it has chemicals that will kill the frys once they hatch, its poison. some people say you can really boiled it good, but i don't trust any chemicals that the small frys might encounter. any peat moss that is ORGANIC, but i trust the CANADIAN brand, i'm not from canada but i heard when they say ORGANIC it means its pure ORGANIC, and i have no problem with my frys, i got almost 100 percent success
