Winter temperatures: Greenhouse V Potting Shed
Hi. I have a greenhouse in which during spring, summer and autumn, I keep a large number of plants which are almost frost hardy, but not quite. (Cacti, Mediterranean plants etc) In winter at the moment I either have to keep them in the greenhouse and heat it when temperatures drop really low (very expensive and not really cost effective for the number which die) or move them into my conservatory (unsightly and very inconvenient).
I am thinking of getting a potting shed, thinking that in winter, the temperature would be just sufficiently high to keep these plants without any heating. In summer, of course I would use it for other purposes. Can anyone give some rough indication of the difference in winter temperature between an unheated greenhouse, and an unheated wooden potting shed which has half the roof and one side, plus the door windowed. If a rough indication can be given I would be able to guage whether my particular plants would survive OK. NB: I live in Essex.
Many thanks in anticipation. Alun
