  • Cities may have stricter limits or restrictions on growing, so check your local laws.
  • Take extra precautions to ensure that only authorized adults have access to marijuana plants. If the home has residents under the age of 21, the grow area must be enclosed and locked in a separate space that the minors cannot access. Children and pets should be kept away from plants at all times to prevent accidental ingestion of marijuana. 

Can I sell home-grown marijuana to others?

What are the rules for growing marijuana if minors live at my home?

A new law passed in Spring 2014 requires any home with residents under the age of 21 to enclose and lock any marijuana grow area in a separate space that minors cannot access. For minors who visit, the owner is responsible for taking extra precautions to ensure that they do not have access to marijuana plants. Children and pets should be kept away from plants at all times to prevent accidental ingestion of marijuana.

Are there safety and health precautions that I should follow for marijuana home grows?

  • Make sure all lights and other equipment are installed by a licensed electrician.
  • To prevent mold growth, make sure the walls of your grow area do not easily absorb water (painted concrete or plastic are best). 
  • Make sure the growing space has plenty of ventilation to get rid of excess heat and moisture.
  • Avoid the use of pesticides or fertilizers if possible.
  • If pesticides or fertilizers are used, make sure they are stored in locked cabinets, out of the reach of children.
  • Only use carbon dioxide generators that are safe for indoor use.
  • Change clothes and shoes when leaving your indoor grow area to prevent tracking of THC and growing chemicals to other areas of your home.
