Yes it’s that time of year again, when I make up a hot bed (or homemade ‘hot box’), ready to help propagate heat-loving seedlings such as tomatoes and peppers. We put the frame back in the Little Tunnel a week or so ago so the wood could dry out after standing out in the cold for months; and then today I filled it up with barrow-loads of fresh horse manure, soiled straw and wood shavings from the nextdoor horse stables. I added a bit of water as I went, just to ensure that the straw wasn’t too dry for all that lovely biological activity to happen. Then I turbo-screwed in the ply-wood front, filled the frame up to the top with more manure and straw/shavings, and finally placed the old recycled door on top which acts as a lid/bench top for the module trays to stand on. Hopefully in a few days the heap temperature will have crept up to around 60-70C, then started to drop down again; to leave us with a nice warm 10-20C continuous heat for sowing the seedlings next week!
