We used hot beds for years, the ideal was a bale of straw in the base, plenty of very fresh manure on that,( we had horses) another bale of straw then top soil. It would then be covered and left for a couple of weeks to start working. It would gently steam as it heated and as we always started late February and it did have covers soon got up to heat. The straw helped the manure to breath and start working, the covers, glass lights, could be lifted to let in more air. Why you would make one now though five days is not enough time to get heat. I grow melons in the greenhouse but they will grow outside in a sunny sheltered spot, use fLeece on cool days or nights.
They take time, Monty must have had his tongue in his cheek when he made that poor excuse for a hot bed.
