Michigan became the tenth state to legalize recreational marijuana use during 2018’s 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 the moisture and temperature are 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 a lot of 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 get more into that in just a bit.
In our continued efforts to educate homeowners, we are going to explain why closed cell spray foam is the best insulation for a grow room.
Best Insulation for a Grow Room
If you’re to a point that you plan to grow marijuana, you know all about how to get the perfect crop, but what about the insulation to maintain the room?
You can have the best strains in the world, but according to Marijuana Venture if you don’t have the environment of the room perfectly set, then you are destined for failure. This happens because the insulation you chose doesn’t create an air seal.
An air seal in a grow room is very important as it helps control the temperature and avoids any problems with moisture. Marijuana Venture recommends insulating the envelope of the room or building, which means from the top to the bottom, with closed cell spray foam.
A good insulation contractor will also recommend closed cell spray foam because it creates an air seal and doesn’t allow any moisture to move through it. The material also doesn’t retain any water, which in the case of a cannabis production building, is a good thing.
A good contractor will also recommend leaving the foam exposed on the walls and ceilings, as any drywall or paneling will bring you back to problems with moisture retention in those materials. If you want to change up the look of the walls and ceiling, the spray foam can be easily painted.
Let’s talk about why all this moisture control is a good thing.
Imagine this – your grow room is inside a metal building and you have fiberglass on the walls and ceiling. All of the moisture in the room is going to cling to that fiberglass which will soak it. That moisture is then held against the metal building causing it to rust and mold to grow in the fiberglass.
You won’t have that headache with closed cell foam insulation, because again, it won’t retain the moisture in the air. This is why it is the best insulation for grow room walls and ceilings.
Foam Insulation for a Grow Room
Closed cell spray foam is going to be the best choice for your grow room because it is going to help control the temperature and humidity you need to grow the best product.
Spray foam will make the room the airtight, conditioned space you need it to be for your plants to successfully grow.
