Actually most hot boxes are heated with heat cable. The decomposing stuff was mainly before electricity but I am sure a few people still do that.rainbowgardener wrote:I'm not very familiar with growing radish, but the carrots do say plant "as soon as the ground can be worked."

Is your hotbox the same as a cold frame or is it one that is heated by decomposing compost?
