My propagation beds are being kept snug by Jemp soil-warming cables, which are easy to install and economical to run. They are priced from £17.95 to £46.95, depending on the specification, plus another £43.95 for the JempStat thermostatic control. These essentials are accompanied by a page of crisp, clear, comprehensive instructions and tips. For instance? A cable becomes more pliable if you run power through it for a few minutes. And be sure to use horticultural sharp sand because builder's soft sand contains impurities that will form a hard lump.
This system costs a lot more than buying a paraffin heater, but is a clear winner when convenience is taken into consideration. A compact Findlay Irvine Autoheat, powered by electricity, has been on standby for really cold nights.
