On Oct. 17, many Canadians will have the legal right to cultivate small amounts of cannabis at home.
But just because something is legal doesn’t mean it’s without potential pitfalls.
Here are some of the questions aspiring green thumbs will want to consider before potting pot plants indoors this fall.
Will it damage my home?
The governments of Manitoba and Quebec have pre-emptively banned home growing, but elsewhere across the country, households will soon be allowed to grow up to four cannabis plants at a time — a limit chosen by the federal government to minimize the health and safety risks of cultivation.
However, some in the real estate and insurance industries warn that growing even a few plants inside isn’t safe. They say grow lights pose a fire hazard and the high humidity required for successful cultivation encourages mould.
Mike Dixon, environmental science professor and director of the Controlled Environment Systems Research Facility at the University of Guelph, disagrees. He says the amount of moisture produced by four plants wouldn’t be nearly enough to encourage mould.
“The history [of home damage] has been based on grow-ops, where you’re growing hundreds of plants and producing hundreds of litres of water,” Dixon said. “With four plants? Nah.”
