Gone But Not Forgotten
Crazy woman wants another one slightly larger than the first one. If not for the wind and the plastic not lasting more than 3-4 years I would just do a tube frame one. I need to do some heat load calculations and see if my boiler is big enough to run another one. If she was happy with 60 degrees it would help a lot. I am leaning toward doing all the seed starting in the first greenhouse and then transferring the plants to the second one to finish them. I may try a double plastic flat ceiling in the first one where I would have a 4" air trap to keep the heat down lower. It takes a lot of btus to heat with all that glass and plastic.
