To start off with, what is Mylar I hear you ask? It is a trade name predominantly used in the US and UK referencing biaxially-oriented polyethylene terephthalate (boPET). It is also sometimes called Melinex or Hostaphan which are two of the other most common names.

The prime traits of Mylar are its high tensile strength, chemical stability, reflectivity, transparency, electrical insulation, and gas/aroma barriers.

It is however more commonly referred to as polyester film, which was created by a company called DuPont in the early 1950’s. Due to its superior durability, heat resistance and strength the use of cellophane steadily gave way to Mylar during the 1960’s.

How can this material help with the growth of plants?

Mylar sheeting is a perfect material to aid in plant growth due to its high reflective properties. Applying the sheets to the walls and floors enables the light to bounce around the room to create as much light as possible for the plants to absorb.

A vast amount of the Mylar sheeting available usually incorporates a white backing to prevent the least amount of light as possible leaking through, and due to the strength possessed it is extremely durable.

The added bonus is the aroma barrier within the material also prevents any pungent smells from escaping, which is ideal if you are using the Mylar for indoor growing purposes.

In any indoor growing in general the more light you can provide for your plants the more yields you can gain as a result.
