The top 3 recommendations and buying guides

Our recommendations

the Reflective film We recommend Eco Diamond from the Easy Grow (Mylar) brand for two reasons: on the one hand, because of the special structure that ensures better diffusion of light and enhances the reflective effect; and on the other hand, because it is particularly extensive with dimensions of 1.25 by 100 meters (width by length) and is also able to completely line a larger greenhouse. With the right accessories (reflective adhesive tape), the reflector foil can be attached in no time - whether on the walls, on the ceiling, on the floor or anywhere in the grow room.

In contrast to the reflector foil from Easy Grow, the variant of Weedness is not kept in silver, but designed in black and white. Due to the white coating on the inside, the film has a particularly high reflective power. On the other hand, it is completely black on the outside. Like the winner in our comparison, the reflective tape is supplied as a roll - it is just as wide and half as long, but also significantly cheaper to buy. For most plant growers, the dimensions should be absolutely sufficient. The previous Amazon reviews (as of February 2021) are positive.

The inexpensive reflective film from Tancuder differs from the other two products in our comparison just by the way it is presented. This is because it is supplied in the form of individual sheets of foil. Each sheet measures 210 by 120 centimeters. This version is ideal if you just want to line a small greenhouse or mini grow room with reflective sheeting. Like the Weedness version, the reflective film from Tancuder is not specially structured, but tends to be kept smooth. You will also need reflective tape to fix it here. The majority of Amazon reviewers are happy with the foil sheets.

Purchase criteria

material

Reflection foil usually consists either of aluminum or of a suitable plastic, in particular a specific polyester variant. The latter is also the better solution because it is more tear-resistant and therefore more stable. Reflector foil made of aluminum is actually only recommended if it is relatively thick - for example double-sided.

structure

To date, most reflector foils have a smooth surface. However, there are now numerous foils that work on the principle of high-quality reflector sheets. That is, they are endowed with a specific structure. Targeted elevations on the film have the effect of enlarging the surface. This in turn ensures that the reflective film can reflect more light and make it available to the plants, which of course benefits them.

Thickness / Strength

The thickness or strength of the reflective film largely determines the durability of the useful plant growth aid. The following applies: the thicker the reflector film, the better it does in terms of robustness, tear resistance, general resistance and longevity.

colour

Generally speaking, reflective film is designed in a classic silver color. As a result, it often looks like ordinary aluminum foil from everyday kitchen use (but is of course much more robust). However, there are also more and more variants that are black and white. A white inner coating has the potential to further intensify the power of reflection. In principle, however, both color versions (silver or black and white) are very effective.

Dimensions

There is no universally valid right or wrong when it comes to dimensions. What matters is how big the film has to be to cover your individual needs. In addition to the width, the length in particular plays an important role. Speaking of rolls: reflective foil is processed and delivered either as a rolled piece of goods or as a set consisting of many individual foil sheets. There is a certain flexibility associated with both variants, which is why no solution can be chosen as the clear winner.

Self-adhesive film / assembly

The trade only thinks of a few self-adhesive reflective foils Greenhouses(€ 60.76 at Amazon *) ready. Basically, these variants, which are so rarely found, logically form the simplest and most convenient solution. Fortunately, even without this feature, it is not too difficult to attach the reflective film in the grow room. Simply use suitable, at best equally reflective, adhesive tape.
