While this may not be the EXACT recipe, It's pretty darn close. Fox Farms makes an organic fertilizer mix called "seafood dinner for your plants" or something like that, from what i understand it is basically the same stuff they put in the ocean soil mix. so if you can get your hands on some of that (its between $10 - $15 bucks for 4 pounds of it, which goes a really long way), all you need to do is buy a quality organic potting soil. The stuff I use is produced about 40 miles from where i live and is really high quality, but also not too pricey at under $4 per cu. ft.
So you get a high quality organic soil. mix in a proper dose of the "seafood for plants," add the appropriate ammounts of coco, perlite, vermiculite, and either earthworm castings, bat guano, or both and you have your own Fox Farms quality potting soil at a more economical price. I have used the Fox Farms pre-mixed in the past and while I find it works excellently i believe this DIY version is just as good. sometime in the near future i will try doing a side-by-side grow with clones and see if my claims hold up in a more scientific setting.
Anyway, if you swear by fox farms, go ahead, it is truly great soil, perhaps they best you can buy. but if you are strapped for cash, try this and you may be surprised by the results.
