Tumbler Compost - Looks like steam but doesn't feel like it!
I am new to backyard composting, and my wife got me a YIMBY 2 chamber tumbler to get started. I make juice almost every morning, so have a healthy supply of fresh greens available.
I've been putting my juice pulp, plus other compostable scraps in the bin for about a month now, in addition to dry leaves, dry grass clippings, paper towels, toilet paper rolls, and any other compostable cardboard sources i can find which are easily cut down to size. But pound for pound, I have more greens than browns, I think.
The other day, when I opened the bin, I saw what looked like steam - but on further inspection it looks more like pollen/a fine dust coming out of the compost.
There are *lots* of fruit flys in the bins, and the inside looks like it's turning black - but it doesn't smell. I am worried it's turning anaerobic, but don't know how to check/what to do.
Any feedback or thoughts are much appreciated!
Thanks so much,
