Michigan became the tenth state to legalize recreational marijuana use during the 2018 midterm elections.
With 10 states allowing recreational use and 33 states legalizing medical marijuana over the years, more and more people are growing their own plants for either recreational use or to provide the herb to patients who have cards.
Just like any project you build, insulation needs to be a concern. This is especially true for grow rooms, as controlling moisture and temperature is very important. The space where you choose to build your grow area could be a room in your basement or an outbuilding you put up on your property. Either way, the right insulation plays a major role.
RetroFoam of Michigan has insulated many grow rooms over the years. With that experience, we know the best insulation for grow rooms is closed cell spray foam, as the wall cavities will be exposed. We promise to discuss that in a bit.
In our continued efforts to educate homeowners, we will explain why closed cell spray foam is the best insulation for a grow room.
Best Insulation for a Grow Room
So, you've got everything lined up to grow the perfect crop, but have you thought about the insulation in your grow room?
You could have the best strains on the market, but as Marijuana Venture points out, if the environment in your grow room isn't spot-on, you're setting yourself up for disappointment. And a lot of that comes down to the insulation -- or, more specifically, whether it creates a solid air seal.
An airtight seal in your grow room is crucial for controlling the temperature and keeping moisture in check. Marijuana Venture suggests insulating the entire envelope of the room or building -- from top to bottom -- with closed cell spray foam.
An experienced insulation contractor knows that closed cell spray foam not only creates that all-important air seal but also keeps moisture from sneaking through. Plus, it doesn't hold onto water, which is a huge plus in a cannabis production setup.
They'll probably also advise leaving the foam exposed on the walls and ceilings because adding drywall or paneling can bring back the moisture issues you're trying to avoid. If you want a different look, no worries -- spray foam can be easily painted.
Now, let's dive into why controlling moisture is such a big deal.
Picture this -- your grow room is in a metal building, and you've used fiberglass insulation on the walls and ceiling. All that moisture in the room will cling to the fiberglass, soaking it through. That moisture then sticks around, leading to rust on the metal and mold in the fiberglass -- definitely not what you want.
With closed cell foam insulation, you won't have to worry about that because it doesn't hold moisture. That's why it's the top choice for insulating grow room walls and ceilings.
Foam Insulation for a Grow Room
Closed cell spray foam is the best choice for your grow room because it helps control the temperature and humidity needed to grow the best product.
Spray foam will make the room the airtight, conditioned space your plants need to grow successfully.
