White mold in your compost is something to be desired – it tells you that you compost is in the 100-140F range. I took a reading on the surface of the compost and was at about 110F. You need about 150F to kill seeds, and that will entail having the right mixture of greens and browns on hand, and the ability to turn the compost when it enters a cooling phase. I just got some rabbit bedding from a friend, which seems like a super desirable material – I always see it in the combustion zone.
Anyway, my goal is to get my compost working ASAP as I will need to plant my whole garden with it. My experience is that it works better than store bought compost.
In some ways compost is like the root crop of your garden – it along with sun and water kind of power everything else.
