convert a soil warming cable into a heating mat
In article ,
says...
Hi I have a soil warming cable and thermostat that I used to have in a sand
box on a bench in my greenhouse. However it was very heavy and my bench
collapsed. So I thought I would update my bench and propagator and use the
soil warming cable to make a pad similar to this.

So what type of material should I use to make the pad from? And how would I
fix the cable to the material? I suppose I could put it in the middle of
two layers and sew it in place with nylon fishing line but would that melt
with the heat?
I did try using a sheet of expanded polystyrene but the cable is melting
into it plus I used cable clips and they keep coming out of the polystyrene
and I am worried it might catch fire.
So any suggestions?
Thanks, Jenny
Sorry but if you have to use your cable make another sand bench there is
no other safe way (make it on the ground) you could change to heat mats
which are much lighter and they just have a layer of capillary matting
over them so hardly any weight at all.
