I've got a load of cuttings and exceptionally slow growing geraniums that I think I'll have to overwinter. All I have is one of those mini greenhouses. Do you think using clear plastic boxes (the type you get in pound stretcher or ikea) would work as a DIY cold frame? I'm thinking maybe some bubblewrap or polystyrene on the bottom would help with insulation.
