I've been growing soil for a few years now and haven't bothered using anything more then 1 part perlite 2 part soil, and miracle grow. Time for some Obama? Now if someone could help me pick out some stuff. I've been eye-ballin this guy http://stores.ebay.com/Blue-Mountain-Organics Looking to buy a bottle of "grow" and another of "bloom". But I notice those two products already contain bat guano and worm casting so should I bother buying & mixing the raw stuff in with the soil? If so when would I mix in the bat guano? In the initial soil mixing or adding in as top soil when I flip to flower? Also if I use this guys liquid nutes should I bother with bone & blood meal? Thanks guys!
