Compost tumbler questions
I have just purchased my first compost tumbler, which has a 230L capacity. I was wondering, since I don't currently have a garden shredder to make shredded wood, what can I add to the mixture to sufficiently aerate the mixture? Should I go to the garden centre and purchase bark mulch, and use that?
Also, can I keep the compost tumbler in my greenhouse so that it heats up the greenhouse interior? Or would it give off soo much CO2 that the plants would suffer problems with toxicity? With energy costs becoming silly, using an electric heater will be expensive (a propane heater less so, but still expensive) so any extra heat would be welcome.
Finally, is it better to transfer the 'compost' from the tumbler when finished into a conventional compost bin so the worms can have a go at it, or should I put it in my small wormery, or should Iin fact just use it as a mulch?
