4 Year | 6 Mil | Diffused Greenhouse Film

LUMINANCE® has been specially engineered to give you the results you need from a highly diffused greenhouse film.

Benefits
  • Lowers greenhouse temperature by as much as 9°F when compared to standard film.
  • Produces higher-yielding plants with stronger than normal root systems.
  • Less demand for watering.
  •  Diffused greenhouse film inhibits fungus spore development for healthier plants.
  • Inhibits insect propagation.
  • Provides comfortable working conditions during harvest season.
  •  Greenhouse plastic film prolongs the growing season.
  • Allows for an earlier harvest-up to three weeks earlier harvests have been recorded.
  • Higher crop yields and higher first quality crop yields-there have been noted increases of 30%-40% in total crop yields, with a higher percentage in first quality crop yield of up to 85% for some crops.
  • Guarantees harvesting days-LUMINANCE® greenhouse poly film provides a cover from the weather to ensure rain won't delay harvesting.
  • Diffused light reaches plants from many different angles, helping prevent the plants from getting scorched.
  • Par light transmission remains the same.
  •  This greenhouse plastic cover is beneficial for raspberries and blackberries.

Get the Most out of Your Light Diffusing Film
• Reduce or eliminate overspray with pesticides containing chlorine, bromine, fluorine, or sulfur.
• Do not use foggers or smoke generators with any chemical containing chlorine, bromine, fluorine or sulfur.
• Avoid direct contact with PVC products in general, and especially PVC pipe or plasticized PVC tape.
• Avoid direct contact with oil-based paints or products containing petroleum distillate, e.g. wood preservatives.
• Do not substitute white paint for shade compounds designed for greenhouse film. Latex house paint may contain fungicides containing sulfur, halogens, etc.  If repeated or prolonged contact with any of the above is unavoidable due to required cultural practices, reduced film life may be inevitable. The greater the contact, the more affect it will have on the greenhouse plastic film. 

Diffusion reduces shadows and allows the plants to receive a more even distribution of light during the day. Although the intensity of light at any one point in time may be lower under a diffused film, the total light transmission is excellent and the plants may actually utilize more PAR light through the course of a day, with less stress. This is due to the more even distribution of light at crop level. By eliminating shadows and spreading available energy more evenly on the leaf surface, there is less stress on the top canopy of the plant and more photosynthesis occurring in the lower canopy.

The appearance of diffused greenhouse film is considerably different than standard polyethylene film. This is due to the diffusion (scattering) of light through the greenhouse plastic film. Plants utilize diffuse and parallel light, while our eyes “see” mostly parallel light. This causes a diffused greenhouse film to look dark and hazy compared to a “clear” film, even though the total light transmission remains the same.

Our Greenhouse Films are bee compatible. This feature provides an environment where natural bee pollination can occur in greenhouse vegetable crops. Pollination of greenhouse vegetable crops is more efficient with bee compatible films than with mechanical pollination. Bee compatible greenhouse films allow more of the UV spectrum to pass through the film. The visible light spectrum for bees extends into the violet and ultraviolet (UV) light region between 350–400 nanometers. This range of light is invisible to the human eye, but by allowing transmission of some of this UV light, the greenhouse will be a more comfortable environment for bees to navigate.  Expected greenhouse film life and typical properties of the film are not compromised with the addition of bee compatibility.

Many American’s are trying their hand at agriculture. If you’re trying to test out your “green thumb,” the best course of action is to build your own greenhouse. Creating your own greenhouse will give you total control over the environment that you hope to grow your crops. With the right greenhouse cover, you can manually maintain the heat, humidity, and light that enters your growing area.

To help you grow any type of plant year-round, we’ve compiled the does and don’t of choosing the best greenhouse plastic coverings.

How to Pick A Greenhouse Plastic

When you first set out to build your greenhouse, you might be tempted to pick up the first greenhouse plastic sheeting you stumble upon. Be aware, not every greenhouse plastic film is created equally. To make sure that you choose the best greenhouse plastic, we’ve listed the qualities you should look for:

Durability

When selecting the optimal greenhouse film, you have to consider the variables of your local climate. Most areas will be subject to harsh environments, whether it’s the blistering sun, downpours, or mountains of snow. When you buy greenhouse film, you need to make sure that it’s tough enough to avoid any tears and be treated to sustain the constant barrage of UV rays from the sun. If your greenhouse plastic is damaged, it’s effectiveness can be significantly reduced.

Opacity

Depending on the types of crops you hope to harvest will determine which greenhouse films are right for you. It used to be a regular occurrence to see a greenhouse that was actually green in color. However, as most growers are trying to let in the maximum amount of light to induce photosynthesis, many growers transition to clear greenhouse vinyl.

Keep in mind, some plants that require strict light discipline and special greenhouse plastic have been developed to inhibit light from entering the space.

Thickness

It might be easy to assume that a thicker plastic sheet is the best choice. This isn’t necessarily the case, as the structural integrity of the greenhouse’s frame will dictate the optimal greenhouse plastic weight it can withstand. While a heavy sheet will be more durable, if snow builds on the top of the greenhouse, every ounce will soon start weighing down on the supports.

Anti-drip and anti-dust

Once again, your local climate will determine how much you need to consider choosing either an anti-drip or anti-dust greenhouse film. Colder climates tend to be prone to condensation that can develop on the inside of your greenhouse plastic. Droplets that fall from the sheet can easily make their way to the plants below, affecting your careful watering regiment by introducing mildew.

Choosing a greenhouse plastic with anti-dust properties is a necessity for many growers, as dust can drastically obscure the light from effectively entering the greenhouse. Standard plastic sheets that haven’t been treated to repel dust usually carry an excess charge on its surface, which can attract dust particles.

The Best Greenhouse Plastics

Polyethylene

Polyethylene is the most common greenhouse plastic on the market. It’s easy to come by and is the most economical option. There are different grades of polyethylene, and if you’re choosing this material for your greenhouse, make sure that you select one designed specifically for agriculture.

Because polyethylene is so inexpensive, it’s also the greenhouse film that’s most likely to suffer from casual wear and tear.

Polycarbonate

An upgrade from polyethylene, polycarbonate provides more durability but at a higher price point. These plastic sheets are usually constructed as a composite of corrugated polycarbonate sheets lined by external polycarbonate sheets. Providing superior resilience over polyethylene, many growers opt for this lower maintenance option.

Polyvinyl carbonate

Polyvinyl carbonate, also known as PVC, is the most expensive option when choosing transparent greenhouse plastic. It’s not a common choice, as PVC doesn’t normally come in lengths easy to work with when constructing your greenhouse.

Avoid These Greenhouse Plastic Mistakes

One of the most obvious mistakes you can avoid when selecting a greenhouse plastic is making sure you get one suitable for a greenhouse. If you’re a novice grower, you may be tempted to purchase a cheap plastic tarp from your local hardware store. However, this can have significant ramifications to the plants you hope to grow.

Most hardware stores will carry plastic sheeting, however, they generally won’t be UV stabilized, meaning that the sun will quickly disintegrate your greenhouse’s cover, leaving your plants exposed to the elements.
