So I have a plan for some simple 6 frame nucs. The best solution for a roof atm is probably using them in pairs making an eke that overlaps like a wbc lift and using one of those plant trays. That would then enable feeding/fondant and roof cost would be about £12..Do any have any simple cheap roof constructions? Once I get 1 knocked up I’ll know some exact dimensions, just looking for ideas atm.
