Hello everyone, I'm new to this forum so bear with me as I fumble with how to use it. I bought Joe Jenkins's humanure Handbook last year, recommended by a friend, and have found it very educational to say the least! I am struggling with getting enough heat. I can't seem to get it higher than about 60-80'f. I feel I have followed all the instructions and youtube videos and yet I still have issues. I'm using sawdust from a local lumber mill for my indoor toilet. In compost bin I use straw or hay for a cover. I believe it's going anaerobic, compressed near bottom as it's hard to probe thermometer. It is breeding big flies! Yes I'm putting enough straw on top but I think there's enough space for insects to go between straws. Help please!
