This photograph shows the 12v heating cable which can be used instead of the heating mat. It will provide the base heat for propagation.

The 12v heating cables positioned on top of sand, above the cables fine grit is added which will distribute the heat from the cables efficiently.

The use of fleece in plant propagation. The fleece allows photosynthesis to continue but at the same time restricts water loss from the plant.

This photograph shows a modern closed case. The temperature can be controlled with bottom heat and air temperature heating units. Glass has been replaced with ribbed plastic – this is safer and lighter in weight. Remember high light intensity is not required in most propagation methods.
