Marijuana Grow-Ops are big business in Canada. However, this type of business comes at a high price and it is often unwitting property owners and neighbours who end up paying.

Grow-ops typically require 3 to 10 times more power than a traditional home. To avoid detection, growers may by-pass the electrical meter and utilize unsafe electrical wiring. Both of these are dangerous undertakings and are often the cause of house fires.

Grow-ops elevate the temperature and humidity levels in the home by approximately 25 degrees. This simulated environment is ideal for the growing of marijuana. A negative consequence of this simulated environment is the growth of toxic mould which forms on walls and ceilings.

Risks to the neighbours are as follows:

  • hazardous chemicals such as fungicides and pesticides are disposed of down the household drains into the sewer system;
  • overloading the electrical system may cause a transformer to blow resulting in lost power to the neighbourhood; and
  • fire hazard for neighbouring houses;

To accommodate the grow-op, holes are punched in walls to facilitate the re-routing of electrical wiring and venting.

Usually, a marijuana grow-op has a sitter who cares for the plants and protects the operation. Marijuana grow-ops are an ideal location for organized crime to commit home invasions and steal all the mature marijuana plants. To protect these grow-ops, planters and growers may booby trap the house and doors.
