The past few weeks have been rather chilly to say the least, but we've found a way to warm things up at the allotment. Our Victorian Hot Bed system in the polytunnel is proving a great success, with a soil temperature of 26 degrees registering on the thermometer last week! This compares with only 5 or 6 degrees in the soil outside. We are using the Hot Bed as a heated propagator to get a range of seeds on the go, and are hoping that we will be able to grow salad crops in it all year round.
The main 'ingredient' of a Hot Bed is fresh horse manure, which creates heat as it breaks down. We will be putting step-by-step instructions showing how we made our Hot Bed on the 'Grow It' page, so check back in a few days if you want to know how to make your own.
