Understanding UV wavelengths, pollination and Australian growing conditions Knowledge Centre | Greenhouse Film Science UV-OPEN does not mean all ultraviolet light passes through. UV-CLOSE does not mean every UV wavelength is completely blocked. These terms describe how a greenhouse film transmits selected parts of the UV spectrum, and that distinction can matter for crops, pollinators and growing conditions. The right question is not simply "UV-OPEN or UV-CLOSE?" It is "which

Why mesh size, GSM and construction all matter Knowledge Centre | Shade & Crop Protection Bird netting can look simple, but products with similar mesh sizes can be engineered for very different jobs. The right choice depends not only on aperture and fabric weight, but also on mesh geometry, yarn construction and manufacturing consistency. Mesh size tells you what the net can keep out. Construction tells you how the net is built. 45 gsm | 5 x 5 mm Wildlife-Friendly Fine Mesh 3

How physical exclusion helps protect crops from fruit fly and other insect pests Knowledge Centre | Shade & Crop Protection Close-up of woven insect exclusion mesh. Warp and weft yarns create a stable grid designed to maintain consistent openings For insect exclusion, aperture consistency matters The Question Why does the construction of insect mesh matter? Insect netting may look like a simple piece of mesh. But when its job is to stop insects such as fruit fly from reaching

Understanding traditional round-monofilament Shade Cloth and lightweight monofilament + flat-tape HandyLite Knowledge Centre | Shade & Crop Protection Traditional Shade Cloth Round monofilament construction HandyLite Monofilament + flat tape construction Different construction. Different purpose. A heavier fabric can be the right choice where mechanical robustness matters. A much lighter fabric can still provide highly effective shading when its yarn geometry and knitted stru

Why Creases, Tear Direction and Blown-Film Processing Matter More Than You Might Think Knowledge Centre | Greenhouse Film Science The Question When a large roll of greenhouse film is unfolded, visible fold lines or creases are completely normal. However, many growers are concerned when they see them. A common assumption is: “The fold line must be the weakest part of the film, and this is where it will eventually tear.” It sounds logical, but it is not necessarily true. A fold

The Hidden Impact of Sulphur and Chlorine-Based Agrochemicals Knowledge Centre | Greenhouse Film Science The Question Many growers expect a greenhouse film to last four, five or even more years. However, in some greenhouses, the film begins to lose strength, become brittle or fail much earlier than expected. Why? While sunlight is the primary cause of plastic ageing, certain agricultural chemicals can dramatically accelerate the process. Among the most significant are sulphur

Why More Layers Don’t Always Mean Better Performance. Knowledge Centre | Greenhouse Film Science Diagram representing the production of Greenhouse Plastic The Question One of the most common questions we hear from growers is: “Is this greenhouse film 3-layer, 5-layer or 7-layer?” For many people, it seems logical to assume that more layers automatically mean a better greenhouse film. After all, if three layers are good, then surely seven layers must be even better. The realit

Why High Diffusion Doesn't Mean Lower Transmission. Knowledge Centre | Greenhouse Film Science Understanding Light Diffusion When choosing greenhouse film, one of the most misunderstood terms is light diffusion. Many growers believe that a greenhouse film with a whiter or more “milky” appearance must block more sunlight. Others assume that the higher the diffusion, the lower the light transmission. Neither assumption is necessarily correct. In reality, light transmission and
