I'm the worlds biggest compost snob, but what you've got there is definitely good to go...the potting soil is purely incidental at this point! if you have the space outside, make a compost pile for next season with those ingredients and some charcoal, and maybe azomite. then order the b.d. preps from josephine porter institute(online)-just don't mention weed to them! you'll end up with nearly unsurpassed quality compost! I'm currently running mine at 30% compost to 70% coco coir. you won't believe the smell of your aftersmoke!
