I've since insulated the garage and so hopefully this will make it a little easier to keep at least a reasonable temperature. * The pH monitor I purchased wasn't great quality and I'm also not very careful with accuracy so I suspect that the pH wasn't ideal - I might well invest in better pH monitoring device and hopefully this will make it easier.
