Cheap alternative to capillary matting

[luckydog]

After costing the amount of capillary matting needed for my greenhouse staging  :o, I was wondering if anyone has used an alternative.  Would an old blanket cut to fit & placed over plastic sheeting have the same effect?  Or has anyone else a better solution?   ;D

Sand!!

In effect like a hot bed without the cable.

Then all you do is water the sand.

Thanks Tee Gee.  Will give it a go.

Tee Gee, is that sharp, silver or common 'any old' sand?
