When i did it outdoors i just dug a couple 3 gal wholes with cheap (nonnutes P. Soil). But I use FF everytime. Love. There shit is compost, except, perfectly balance. Its like buying it from your farmer neighbor. My only grip is that that stuff is areated well, but compacts when water wayy to easily. So get a small bag of perlite(9$) or two and wix into your pots at about 15%+/- perlite.
FFOF i think is the best. My next soil tjough, i plan to recycle some old soil and compost some, and try some advanced tecniques, like lining the bottom of flowerin pots with worm castiongs, then transplant and in flower haveing a thick layer of bat guano just at the bottom.
FF butes are great, I'd sy they are the most commonly used for this purpose and there are no complaints. BUT all the old time growers on here SWEAR by botanicaire, I think its semi organic which could be why. Lamp
