GREENHOUSE SHADING

Excessive sunlight can lead to plant overheating, excessive transpiration and lower yields. Proper shading of greenhouses helps maintain optimal conditions for growth, improving crop efficiency and reducing the risk of heat stress in plants.

BENEFITS OF DRONE GREENHOUSE SHADING

Precision and even application

Drones deliver accurate coverage of the greenhouse surface. With modern navigation and application control systems, every layer of coating is spread evenly, giving crops effective protection.

Speed and efficiency

Drones work much faster than manual methods or ground-based spraying. They can cover large areas in a short time, so greenhouses are quickly protected from excessive sunlight.

Savings on water and product

The right coating rate with no unnecessary losses. Precise dosing reduces the amount of shading product used, which means lower costs and less environmental impact.

Safety

No need to work at height. This removes the risk of accidents associated with traditional coating application, making the whole process safer for workers.

Tailored to your needs

We can apply different types of coating to suit the crop. Depending on what the plants need, we can use coatings with different levels of shading and durability.

Minimal disruption to growing

Application by drone is non-invasive and does not require day-to-day work in the greenhouse to stop. Drones can work even in hard-to-reach places without damaging plants or infrastructure.

HOW WE CARRY OUT DRONE SHADING

A drone is the right tool where a roof-mounted machine cannot get access or the greenhouse structure does not allow it, and for large, scattered sites. The result depends not on the volume of liquid but on the thickness of the layer on the covering – which is why we keep a close eye on the product rate and the application conditions.

Application conditions

  • Clean, dry covering – moisture on the film dilutes the coating layer.
  • New film: we first remove the greasy surface layer, otherwise the coating will not hold well.
  • Relative humidity below 80%, with no rain for about 12 h after application.
  • Temperature of approx. 10–25°C – the coating must dry before the night-time dew.
  • Wind max. approx. 7 km/h – in stronger wind the layer is too thin and drift increases.

Rate and evenness

  • The same product rate per hectare as with machine application – just with less water.
  • Too little product: weaker shading and lower resistance to wash-off.
  • Too much: the crop loses light, and with it yield and quality.
  • We choose the rate to suit the crop, the time of year and the product manufacturer's recommendations.
  • We adjust droplet size to the weather – using nozzles or the spinning speed of the atomiser disc.

Removing the coating

  • At the end of the season we apply a coating-removal product by drone.
  • The covering must be dry and completely wetted – any missed spots will not come off.
  • After at least about 15 min, rain or brushing removes the coating.
  • Before application we check the drainage – water from the roof must not reach the irrigation water tank.

Safety

  • Flights are carried out in line with UK CAA rules and the operational authorisation.
  • A designated, safe take-off and landing area.
  • The operator keeps the drone in sight throughout the flight over the roof.
  • No one is in the greenhouse during application.

GREENHOUSE AND POLYTUNNEL ROOF WASHING BY DRONE

Dust, soot, algae, bird droppings and shading residue can take anything from a few to over ten per cent of the light away from your plants. In horticulture, the rule of thumb is that 1% more light means roughly 1% more yield – so a clean roof is a real gain. The drone cleans the covering without anyone going onto the structure and without a heavy machine on the roof.

When to wash

  • In autumn or winter – after the season and once the shading has been removed, before supplementary lighting.
  • Before the spring crop start-up, when light levels are at their lowest.
  • After dusty work nearby, grass fires or pollution from roads.
  • When you can see a green film of algae or streaks on the covering.

How it works

  • We inspect the roof, the type of covering (glass, film, polycarbonate) and the water drainage.
  • The drone applies the cleaning solution evenly across the whole surface.
  • The product is left to work for the time recommended by the manufacturer.
  • The dirt is rinsed off – by water from the drone, an overhead sprinkler system or rain.
  • We match the product to the covering so that film and seals are not damaged.

Why use a drone

  • Nobody has to go onto the roof – fewer accidents and breakages.
  • Fast, even on large and scattered sites.
  • Polytunnels and roofs that machinery cannot reach.
  • Less water than hand washing or lance washing.
  • Can be combined with the next job: washing, then shading in season.

What you need to prepare

  • Access to water and space for the drone to take off and land.
  • Working drainage – water from the roof must not reach the irrigation water tank.
  • Vents closed and people out of the greenhouse for the duration of the application.
  • Information about the crop inside and any sensitive plants.
