Customer Questions
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.
