i have recently started using a humus/manure mixture i get from the depot for $1 a 40lb/1cu bag and i add a 15lb bag of earthworm castings and 2 small bags of perlite
to that mix i add some subculture from general hydroponics and some mychorizzae tablets in the pots

here recently i have added some peruvian seabird guano 10-10-2 to the mix at 1cup
and i am getting some seaweed/kelp extract to add to it cause that is supposed to naturally have growth harmones and cheleted nutes and a few other good benefits

i keep on mixing it up alittle but this seems like its a good mix

and i have used it on freshly rooted clones with success
