I was wondering whether any URGlers have experience of keeping cacti in a
polytunnel?

Any info regarding ventilation, heating in winter etc would be good.


I generally keep my cactus as dry as poss in winter but 'frost free' in
our greenhouse.. Its bubble plastic lined & heated with a parrafin
heater.

Me too. I keep the GH at about 5 degrees C and the plants bone dry.
I bubble wrap the inside of the GH and have a small electric fan heater......
