A lot of it is common sense.
I was rather sleepy (jet lagged) when I watched Monty doing his hot bed. What did he do wrong? It didn't look enough to me and didn't look fresh enough. What else?
I used to make a hot bed in the GH from the fresh manure from my horses. In March I piled it up nearly chest high then put a wooden frame on it which I half filled with compost. Then I left it for a couple of weeks, except for watering it to keep it moist. It got very hot and steamy and meant I didn't have to heat the GH for sowing bedding plants. Then when it cooled down a bit I sowed my tomatoes in the compost on the hot bed. Worked well but was a lot of work. I then left it to turn into manure, watering it when it got dry. Then in the winter I dug it into the earth in the GH floor for planting next year's tomatoes. But it took up a lot of room that I now need, although it was amazing how much it shrank while it was rotting.
