With a grid foil you acquire a particularly robust cover for your foiled greenhouse. You can find out what specifically distinguishes this type of film, what you should definitely pay attention to when buying and which products are explicitly recommended in our guide.
Grid film is the robust version of the greenhouse film

Tear-resistant greenhouse film grid film with nail edge from Aquagart I UV-stable film for tomato house cold frame film I fabric film garden film green 250g (6m, green/transparent 2.0m wide)
To the product| broad | 2m |

Our first recommendation is among the most popular grid films on Amazon. The film from Aquagart is available there in various widths and lengths. Measuring two by six meters, the greenhouse film (€15.90) is big enough for most greenhouses (€72.95). The price-performance ratio is convincing, as numerous reviewers confirm. They describe the grid foil as being of very good quality and stable. It's said to be strong enough to be stapled to wood, and it seems to work beautifully when trimmed too. In addition, some report that their plants have never thrived as well as under this film.
our recommendation
Connex grid film 2 x 3 m - 100 g/m² - PP - reinforced with PE thread - UV-stabilized & weatherproof - for the construction of greenhouses & protection against the weather / greenhouse film / cold frame film / FLOR80370
17.23 EUR To the product| broad | 2m |

| length | 3 m |
| color | white/transparent |
| temperature resistant | Yes |

| basis weight | 100gsm |

Compared to the grid film from Aquagart, the greenhouse film with grid structure from Connex is significantly less strong. Its fabric weight is only 100 grams per square meter, which means it is 0.1 millimeters thick. This means that it performs worse in terms of robustness and stability; however, the lower basis weight goes hand in hand with higher light transmission. The white color in which the Connex grid foil is kept also contributes to this. Most reviewers on Amazon are happy with the greenhouse cover. Sometimes, however, it is criticized that it cannot withstand more severe weather conditions - such as heavy hail.

Zelsius cover for foil greenhouse, replacement foil propagation house, 195 x 143 x 143 cm, cover for foil house, greenhouse, tomato house grid foil
44.95 EUR To the product| length and width | each 1.43 m |
|---|---|
| height | 1.95 m |
| color | green/semi-transparent |
| temperature resistant | Yes |
| UV-resistant | Yes |
| basis weight | 135 gsm |
| nail edge | no |
The green, semi-transparent Zelsius grid sheet measures 143 by 143 by 195 centimeters (width by length by height) and features a roll-up entrance that is 160 centimeters high and 88 centimeters wide. It can be easily pulled over a suitable greenhouse - without a lot of time and effort. In terms of thickness, at 0.135 millimeters it is between the Aquagart and Connex models. The majority of Amazon reviewers are positive about the Zelsius brand grid film. It should serve its purpose perfectly. But: Some customers state that the UV resistance is not exactly the best.
Purchase Criteria
Thickness/grammage/area weight/fabric weight
Simple rule: the stronger the foil material, the more robust, tear-resistant and durable the grid foil. But: The feature also affects the light transmission. Thick films let less light through than thinner versions. Keep this in mind and make the right decisions about the plants you want to grow in your greenhouse. By the way: A basis weight/grammage of 100 grams per square meter is equivalent to a thickness of 0.1 millimeters.
Dimensions
When it comes to measurements, there is no real right or wrong. In principle, a longer and wider grid foil is of course preferable - especially if it costs almost the same as a smaller grid foil with similar properties. You should therefore consider two points when it comes to length and width: firstly, your needs (what size do you need for your greenhouse?) and secondly, the price-performance ratio (is there a price difference between grid films that are more or less the same size?).
color
Grid foil is available in white, green or blue. Which color is more suitable depends primarily on which plants you want to cultivate under the greenhouse film. If the plants need a lot of light to thrive, you should prefer white grid foil as it is more translucent. On the other hand, greenhouse film tinted green or blue is recommended if the plants need or want less light.
light transmission
The light transmission is generally slightly less pronounced with lattice film than with smooth greenhouse film. This is due to the lattice structure - it does not let the light through as easily as smooth film. In addition, the thickness, the color and the UV protection determine how translucent the grid film is. The following applies: The thicker, more tinted and UV-resistant the film is, the less light gets past it. Conversely, thin, white and average UV-resistant (UV3) film is relatively transparent to light.
resistance
temperature resistance: It is essential that the lattice foil is comprehensively temperature-resistant - i.e. it has to be able to cope with both heat and cold without any problems. Classic films made of polyethylene are usually resistant from minus 70 to plus 70 degrees Celsius.
UV resistance: UV resistance is also an important feature. Also pay attention to the small print in this regard: Does your selected grid film have "UV3", "UV4" or "UV5" on it? The number indicates for how many years the manufacturer guarantees UV protection for the film. Grid foils are generally UV-resistant for three years. You should replace the foil at the latest after the specified time has elapsed.
youtubefrequently asked Questions
What is grid foil?
Grid foil is PP or PE foil with a grid running through it. This structure gives it additional stability. Grid foil is mainly used in the garden to cover greenhouses. It is also used in the construction sector. UV stabilizers are incorporated to make the grid film suitable for outdoor use.
What is meant by the edge of the nail in grid foil?
Most grid foils have a nail edge on the long sides - a very strong fabric that is about five centimeters wide and makes it noticeably easier for you to attach and fix the foil. In addition, the edge makes the attachment more stable and therefore also more secure and "enduring".
How do I attach the grid film to my greenhouse?
The perforated nail edge, which many grid foils are equipped with, allows you to attach the utensil to a wooden frame without much effort. The pre-punched holes make installation child's play. The same applies if eyelets are attached to the grid foil. If you get grid foil without a perforated edge, simply stick the greenhouse foil on with UV-resistant adhesive tape.
Which is better - a smooth foil or a grid foil?
In principle, both types of greenhouse film can be of high quality. Each also has its specific advantages: While lattice film with its lattice structure is more robust and resistant, smooth greenhouse film lets more light through. To create ideal conditions in the greenhouse, you can cover the roof with smooth foil and the sides with grid foil.
Where is the best place to buy grid foil?
You can find mesh foil for greenhouses in well-stocked hardware stores such as OBI or toom and in garden centers such as Dehner. Amazon offers you a large selection, low prices and a convenient ordering and return procedure.
How much does grid foil cost?
If you compare the costs of different grid foils, you should not pay attention to the final price, but rather to the price per meter of length. In addition, we advise you to only compare slides that have the same width and grammage. With a grid foil two meters wide, the price per meter is usually between five and ten euros.
equipment
UV resistant tape
If you order grid foil without nail edge and eyelets, an adhesive attachment is recommended. It is best to use UV-resistant adhesive tape for this. Ideally, the manufacturer should state in the product description that the item is suitable for use in a greenhouse. In addition, the tape should be transparent so as not to attract negative attention.
