Different Types of Reflective Materials for Indoor Marijuana Grow Room

Building an indoor grow room is probably exhausting for some growers but the rewards of indoor cultivation are satisfying since the entire growing environment can easily be controlled, resulting in greater yield and more potent buds. For a more detailed list of growing equipment necessary for an indoor set-up, a growing marijuana ebook can be a lot of help to growers who wish to succeed in their growing project.

Information about how to set up an indoor grow area can be sourced from the internet but a growing marijuana ebook can provide more organized and detailed information so pot cultivation can be done in a breeze. Selecting the proper surface of the walls of the indoor room to maximize light output is just as important as choosing the right type of light and feeding the plants with the right nutrients.

Below is the list of some the most commonly used materials for the walls that will help in maximizing light output:


It is a polyester film that is highly reflective and can be able to reflect approximately 97% of light back to the plants. It comes in different thickness in which 1mm and 2 mm are the most common. This type of reflective material reflects radiant heat energy so proper ventilation is needed if it is used to cover the walls of the grow room.


It is made of spun polyester fabric reinforced with foil laminate that does not easily fade and tear and is resistant to most solutions. This is a durable version of mylar and though it may cost a bit higher than mylar reflective material, it is more durable and easier to clean without worrying of tearing it down. It can reflect as much as 95% of light.

Flat white paint

It is the best option for a cannabis grow room with big space. It has the ability to reflect 75% to 85% of light and unlike foylon and mylar sheets, it does not create hotspots.

Polystyrene foam sheeting or Styrofoam

Its ability to reflect light is comparable to that of a flat white paint, which is approximately 75% to 85% and is best for an indoor grow room with a harsh environment like the attic. It does not create hotspots and can easily be nailed, glued or taped to the wall.

Elastomer paint

It can provide approximately 90% light reflection. It is highly reflective and mildew resistant that is good to use for grow boxes.

To make sure that no or very little amount of light is wasted, get the walls as close as possible to your weed garden and direct the light pointing to the marijuana plants. A growing marijuana ebook is a good source for growers who want to know more about the advantages of reflective materials and all about growing weed techniques and tips.
