Quick Answer

The greenhouse winterizing products you actually need are a heater sized to your space, a way to monitor temperatures overnight, and a circulating fan to keep warm air moving and prevent frost from settling into cold pockets. From there, add bubble or reflective insulation on north walls, soil heating cables or heat mats to keep roots warm, frost cloth for cold snaps, and a soft snow broom if you live where snow falls. A well-built structure from BC Greenhouse Builders, with insulating glazing and self-opening roof vents, means you’ll need fewer add-ons to keep growing all winter. 

Quick Answer

Yes, a budget-friendly backyard greenhouse kit can absolutely stand up to real wind, as long as the frame gauge, load ratings, and foundation are done right, regardless of whether the frame is aluminum, steel, or wood. BC Greenhouse Builders' economy greenhouse kits, including The Legacy, The Sunhaven, and The Westgrove, meet a standard 85 MPH wind and 32 PSF snow load rating out of the box, with engineering available up to 140 MPH and 100+ PSF for extreme climates.
