Do Grow Rooms Need Reflective Walls?

Do grow rooms need reflective walls











Reflective walls are an important aspect of grow rooms. They help to reduce the amount of heat and light that reaches the plants. Reflective paints have been shown to increase light reflectivity by 85%-95%. They also tend to be easy to clean and inexpensive to purchase. Furthermore, these paints don’t create air pockets that can create extra heat.


Mylar reflective walls in grow rooms are one way to make your indoor space cooler and less drafty. Mylar is a synthetic fiber that can be placed on the walls and ceiling of your grow room. It is also used in space blankets and windshield sunshades. The main drawback of Mylar is that it picks up dirt and reduces light reflection. A better alternative is to use microfiber grow films. They are washable and tear-resistant.

Polyethylene can be used as a substitute for Mylar. It has a black side that blocks light and a white side that reflects seventy-five percent of light. Poly is most effective when 6 mills thick. The film can be installed on walls using tape glue or carpenter’s nails. Using poly will save you money and give you an inexpensive alternative to Mylar.

Reflective walls can be difficult to install in large grow rooms. However, they can be useful for compartmentalizing large spaces and can help increase light transmission through the room. You can also place sheets of reflective material around the edges of the grow room. It’s important to choose a surface that is reflective on both sides. White paint, in particular, is best because it contains no pigments that absorb light. Try to get flat titanium white for the best effect.

Another popular reflective material is panda film. This film is a cheap, effective way to increase reflectivity. Its reflectivity is 60%, which means it will recover more than half of the light that would otherwise be lost through walls.


Mirrors are a common fixture in grow rooms, but they are not always the best reflectors of light. Instead of using a mirror, you can use a diffuse reflector, which will bounce the light off walls and provide even light distribution. But mirrors reflect light from a single spot, which can be a problem for plants.

However, there are some benefits to using mirrors in grow rooms. They are cheap, and they come in many different shapes and sizes. They can also reflect light, particularly infrared light. This is good for your plants, as the light reflected from a mirror will help them absorb the light.

Reflective walls help to keep your growing environment cool. However, they are not the only way to increase heat and light reflection. You should also make sure that you have good ventilation in your grow room. If your grow room lacks adequate ventilation, you should install a fan and a ventilation system.

Reflective walls can be created using different materials. Foylon and mylar come in flat rolls that you can place against your walls. Make sure that you place them flatly against the wall, as any bubbles or creases will reduce reflectivity. You can also use Velcro to attach the material to the wall. This will minimize creasing and tearing of the material. Another option for reflective walls is a “hammer-style” texture, similar to the walls in professional grow tents.

Flat white paint

In order to maximize the amount of light in your grow room, you can increase the reflectivity of the walls. You can choose a reflective wall panel or opt for a flat, white latex paint. In either case, a high-performance reflective wall surface will reflect at least 30% of the light entering the room.

Another option is using Foylon. This material is a bit more expensive, but it has better reflectivity than mylar. It can reflect up to 95% of light and 85% of heat energy. It is also easy to clean and can be treated with fungicides and anti-mildew agents. Foylon is best attached to the walls using Velcro to prevent tearing and bending. However, be sure that the material is bonded flush to the wall, as any wrinkles or rips can cause hotspots.

Aluminum faced wall panels

Choosing the right surface for grow rooms is important because it not only makes the growing environment durable, but also contributes to safety of your equipment. Aluminum faced wall panels feature an aluminum sheet laminated directly to a foam core. If you’re interested in an even higher level of protection, you can consider purchasing aluminum honeycomb panels.

Another popular choice is fiberglass reinforced plastic wall panels. These panels are incredibly durable, moisture resistant, and affordable. The downside is that they don’t provide the same R-values as insulated metal panels. Another option is a polyurethane spray, which is an excellent barrier against air and moisture.
