Hi n2ishunSpecifically ?
My personal mix is 1 large bag FFOF (fox farms ocean forest) and 1 large bag Fox Farms light warrior
Add ~about~ 1.5 cu. ft. of perlite
About 6 cups worm castings
About 3 cups blood meal
About 3 cups bone meal
About 2 cups bat guano (fruit bat if possible...the package will say)
About 2 cups dolomite lime
Maybe a cup of epsom salts
Everythings kinda about'ish since I really never measure.
Mix the shit till if feels like your arm is going to fall off.
Drink a beer or smoke a bowl
Mix some more.
Put it into a large opaque or *clearish* plastic bin with a lid and set it out in the sun for at least 4-5 days. (DO NOT skip this step)
It will sweat and the texture will change dramatically becoming a foamy kind of thing for lack of a better description...once you see it you'll understand.
Mix till arms fall off.
Use freely at this point.
You will need ZERO nutrients during a 10-12 week flowering plants life cycle, long term sats will need a flowering nute only once.
Tap water only, adjust nothing, straight from tap.
As you can see from that grow log I linked JetDro has a particular hate for anything fox farms so he subbed the base soil for SS#4 and Roots organic.
It should be nearly the exact same as FF.
I've also had luck with Miracle grow moisture control soil as the base....it's not quite as good, but it's close.
Walmart used to carry Sams Choice potting soil in a purple bag, it works every bit as well but I haven't seen it in years and think they stopped making it.
Specific enough ?
may I ask what is the approximate volume of the cups you re using?
