a hot heap should heat up to between 150 and 172F within 3 days of putting it together. for me the important thing seems to be a very fine grind-i use an electric rotary lawnmower. the proportion of green and brown doesnt seem to matter-my fall heap is from garden cleanup so lots of green. spring heap is final garden cleanup and lots of leaves, so mostly brown. if you turn the heap every 2 days to maintain heat the compost can be finished in eleven days. despite what you might read, after the initial assembly it doesnt take much time or effort to run a hot heap and if you have space constraints its great- mine goes where the veg garden is in the summer.
