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.
Cultivating marijuana is a fairly new endeavor in some states, so here’s a list of the questions we’ve been asked by growers as they prepare their grow room.
The quick answer is yes, but you shouldn’t get spray foam just for odor control.
Foam insulation creates an air barrier and odor travels through the air, so it can definitely help reduce the odor from seeping out. With that being said, there are things that are out of the control of the spray foam – like doors or other openings.
Spray foam insulation seals up all of the nooks and crannies where it is installed.
Keep in mind, if there is an existing bug problem spray foam won’t fix it. Spray foam will, however, work to prevent future pest problems.
Heck yes, it will!
How you ask? That’s simple. You need to maintain a specific humidity range and spray foam can help with this because it makes the grow room an airtight and conditioned space. Spray foam also doesn’t retain any moisture it comes into contact with.
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.
You need special lighting in a grow room and spray foam allows for that.
The high-pressure sodium lights get pretty hot, but they can safely be a couple of inches from the foam with no worries.
Controlling the temperature in a grow room is super important and spray foam insulation can help.
Because spray foam creates an air seal, it keeps the air you pay to treat right inside that room where you want it. The insulation also works to keep outside air out, thus working to help control the temperature right where you want it.
It depends on which spray foam you decide to go with.
Open cell spray foam does not have a vapor barrier built into it, whereas closed cell spray foam does.
No, it will not let light into your grow room.
Spray foam, whether it’s open cell or closed cell, is dense enough to keep light from passing through it.
This honestly depends on how your grow room is laid out.
If you plan on finishing the walls, the open cell or closed cell will work. If you plan to leave the walls exposed, closed cell is the better option as it is a denser material and can handle the bumps and knocks against it.
All foam insulation contractors have a minimum charge that varies from business to business. Our minimum charge is between $1,600 and $2,000, depending on the scope of the project and the spray foam insulation used.
