We don't really have the space or the dosh to put up a proper glass house, but we have seen several very cheap polythene ones for sale. (Glorified poly tunnels, I suppose)We already have a little one against an outside wall for cuttings, etc., but don't have any idea how useful a full sized one would be. As a place to protect plants in the winter cold, how effective would they be? I don't suppose you could heat them, but are they a waste of money? Does anyone have experience of these?
