Can I use a ShelterLogic GrowIT greenhouse year-round in Canada?
The GrowIT extends your growing season by 4-8 weeks on each end, but isn't heated for deep-winter growing. Works best from early spring through late fall in most Canadian zones.
What size greenhouse do I need for a home garden?
4'x4' for seedling starting. 6'x8' for a small herb/vegetable garden. 10'x20' or larger for serious home growing with raised beds and walkways.

A greenhouse buys you four to eight extra weeks at each end of the Canadian growing season. Here is how to pick the size, cover and frame that suit your yard, from a balcony mini to a 12 x 20 ft heavy-duty hoop.
Raised garden beds warm up earlier, drain better and save your back in a short Canadian season. Compare galvanized steel and FSC wood frames, size a bed around reach and root depth, and find out why September and October are the best weeks of the year to build one.
