Like a large area of sand that you sink your pots in to provide a 
reservoir of moisture and temperature.

ISTR someone mentioned a few months back that as one can get black 
plastic sleeves to grow plants in, there's a version made of woven 
fibre, so a bit like plastic but a bit like clay because it breathes. I 
looked at the web site at the time and great claims were being made for 

Does raise the question why are pots made black, instead of white which 
would be a bit more temperature stable or even metalised - as some 
decorative pots are.
