Reflective Material Questions

Spray glue works great for more permanent applications. Pins or staples don’t really work on their own. If you take packaging tape and place two strips (one on the top and one on bottom) then use staples, then tape, it will increase the Mylar strength to hold and not tear.

Some say you cannot. But I disagree because I know many growers who have vertical or stadium style grow setups. I’ve only seen positive reactions when the plant is stimulated by light from below. If it is not natural, why are they making the trays white?

Mylar: It is reflective, but not more than a clean flat white wall. Mylar will become dirty quickly and lose its efficiency. It is difficult to cut, pin up, and keep flat. Light tends to peer through most types. Also, they are usually sold in smaller roll sizes than Panda Plastic, which in my opinion works a bit better.  If you decide to get mylar, get the thickest millimeter you can. Panda Black and White Plastic: Cheap and easy to work with.  It blocks out the light.  This plastic usually comes in roles that span from the ceiling to the floor. I’ve even seen  walls built out of it using zippers for doors.  But it is shiny, so some of the gloss loses the light intensity. (Flat white paint works a bit better).

Dureflect: Is washable and reflects pretty well. It can also hold up over time. It is a better material for reflective properties than Panda Plastic. Ultra reflective : This stuff works a bit better than Dureflect. ORCA Grow Films: The BEST for reflection and a new product to the market is ORCA Grow Film.  This film is 2X as reflective as Mylar and it is light proof! This stuff is tougher too. I would use this film above all others for reflective properties. It also comes with a roll of tape for the seams.

You can span a role of reflective film from the ceiling to the floor using staples on the ceiling and role length of 1”x1” wood or PVC pipe in the bottom and tape it, to hold the film stable. You can also use insulate sheets of foam. You can run a strip of 1”x1” wood on the ceiling and floor, and then tie the sheets to it. If you are trying to build a whole room, look into the grow tents. I recommend using the Secret Jardin’s, Mammoth, or the Grow Lab.
