Whether you’re cultivating marijuana for personal use or for your business, you need your grow room insulation to be on point.
Spray foam insulation is one of the best options available for grow rooms to achieve the precise environment the marijuana needs to thrive in.
If you’re considering spray foam for your grow room, you probably have a lot of questions. RetroFoam of Michigan has you covered as we’ve compiled a list of the frequently asked questions we’ve gotten concerning grow rooms and spray foam insulation.
Top Spray Foam Insulation FAQs for Grow Rooms
Growing marijuana is still a pretty new venture in some states, so we've put together a list of the top questions we've been getting from growers as they get ready to set up their grow rooms.
Will Spray Foam Keep the Smell In?
The short answer is yes, but don't get spray foam just for odor control.
Spray foam insulation creates an air barrier, which helps keep odors from spreading through the air. So, it can definitely cut down on smells escaping. But keep in mind, there are some things spray foam can't control -- like doors or other openings.
Will Spray Foam Keep the Bugs Out?
Spray foam insulation seals up all the little nooks and crannies where it's installed.
Just remember, if you've already got a bug problem, spray foam won't solve it. But it will help prevent future pests from getting in.
Will Spray Foam Help with Moisture in a Grow Room?
Heck, yes, it will!
Wondering how? It's simple. To keep your grow room at the right humidity, you need it to be airtight and well-conditioned. That's where spray foam comes in -- it helps create that airtight space. Plus, spray foam doesn't hold onto any moisture it touches, so you're covered there too.
Can Spray Foam Be Painted?
It sure can.
When painting foam insulation, it’s best to wait about 24 hours after installation before painting it. This gives any dust that was kicked up during the installation a chance to settle. We recommend spray paint instead of a roller or brush as open cell spray foam tends to be softer than closed cell.
How Close Can the High-Pressure Sodium Lights Be to the Foam?
In a grow room, you need special lighting, and spray foam works great with that.
Those high-pressure sodium lights can get pretty hot, but don't worry -- they can be just a few inches from the foam, and you'll still be safe.
How Does Spray Foam Effect Controlling the Temperature in a Grow Room?
Keeping the temperature in check in a grow room is crucial, and spray foam insulation can really help with that.
Since spray foam creates an air seal, it keeps the treated air right where you need it -- in the room. Plus, it keeps the outside air from sneaking in, so you can keep the temperature exactly where you want it.
Does Spray Foam Have a Vapor Barrier?
It really depends on the type of spray foam you choose.
Open cell spray foam doesn't have a built-in vapor barrier, but closed cell spray foam does.
Will Spray Foam Let Light Inside a Grow Room?
Nope, it won't let any light into your grow room.
Whether you go with open cell or closed cell spray foam, it's dense enough to block light from getting through.
Is Open Cell or Closed Cell Spray Foam Better for a Grow Room?
It really depends on how your grow room is set up.
If you're planning to finish the walls, either open cell or closed cell will work. But if you're leaving the walls exposed, closed cell is the better choice since it's denser and can stand up to bumps and knocks.
How Much is Your Minimum Charge?
All foam insulation contractors have a minimum charge that varies from business to business. Our minimum charge is $2,000, depending on the scope of the project and the spray foam insulation used.
