Thanks got the slides on clearance lol.
It's mainly just composted leafs, no grass. And soil from previous grows goes in the pile too. I dont throw food out there because it attracts too much pests. I use blood meal, chicken poop and alfalfa pellets as my nitrogen sources. The end product is super nutritious. Im not even buying soil for my outdoor grow this year besides starting the seeds in Kellogg's Patio Plus. Everything is growing in 50% compost, 35% perlite, and 15% peat moss.
Btw your piles look like they are gonna net you some rich compost. Nice work.
Do you get a lot of worms? I found about a handful so far
