So what is a hot bed? A hot bed is a warmed, protected environment, created by heat generated from decomposing organic matter. It is used for producing early crops in cold climates, when soil temperatures during winter are too low for seed germination. Using hot beds to increase soil temperature through the cold winter months is a traditional technique and one of the practices used by French market gardens in their intensive polyculture.
Soil temperatures are averaging around 14℃ in the hot bed. We have planted lots of seeds so will give you an update on germination times as we go. Lets hope all the work pays off.
I will be producing a mini guide with all the details for building a hot bed in the near future.
