Systems

The systems that run inside every structure.

A structure is the shell. Climate control, screening, irrigation, cultivation equipment, automation, and the frame and covering materials themselves determine how it actually performs.

Climate & Screens

Screens are used within a greenhouse for climate control, as well as protection against birds and insects. Multiple screen types can be combined within a single unit.

Horizontal screens

  • Energy screens

    Conserve interior energy and climate control.

  • Shading screens

    A "summer screen" for natural ventilation without direct sun exposure.

  • Black-out / light-reduction screens

    Tight blackout control, low maintenance, long lifespan.

Roll & roof-roll screens

  • Vertical roll screens

    Shading, energy-saving, external light reduction, or preventing outgoing light — operated by tube-motors or external motors.

  • Roof-roll screens

    Often installed in garden centers and wide-span greenhouses, improving temperature and climate circulation.

Insect screens

  • Insect screens & curtains

    Prevent insect infestation, available in multiple mesh sizes for large flying/crawling and small/microscopic insects.

Cultivation & Automation

Six equipment categories make up a complete cultivation system, from growing media to process automation.

Climate & heating

  • Heating
  • Cooling
  • Climate Control Systems
  • Air Circulation Systems
  • Dehydration Systems

Irrigation

  • Fertilization Injection Unit
  • Drip Irrigation
  • Irrigation Room
  • Irrigation Boom
  • Pond Liners

Growing system

  • Growing Media
  • Pots / Containers / Trays
  • Ground Cover

Internal transport

  • Chain-driven transportation systems
  • Crop-care machines
  • Harvesting carts
  • Monorail systems

Electro-tech

  • Process automation
  • Lighting
  • Measuring & control equipment
  • Weighing equipment
  • Computer equipment

Safety & sanitary

  • Hygiene stations
  • Disinfecting mats
  • Disinfecting materials for equipment
  • Insect lights
  • Disinfectants

Materials & Engineering

Most greenhouse frames are made from wood, aluminium, galvanized steel, or PVC. The most widely used covering materials are polycarbonate and polyethylene film.

Frame materials

MaterialAdvantagesDisadvantages
AluminiumDurable, rust-resistant, lightweight; won't rust; won't grow mold or pathogens if cleaned periodically.—
Galvanized steelStrong; resists rust for many years if powder-coated; cheaper than aluminium.Requires more care, including periodic resurfacing.
PVCCheap, quick to erect; can be bent into arches for better water shedding, or joined into traditional structures; lightweight.Only suitable for temporary greenhouses / cold frames.

Covering materials

MaterialAdvantagesDisadvantages
Glass~90% light transmission; good air exchange; reduces fungus risk.Difficult to maintain, prone to leaks; more expensive; heavy; prone to breaking and vandalism; limits achievable shapes.
Plastic filmLightweight; usable on a wide range of designs; virtually no leaks; better insulated; inexpensive to install.Short lifespan; condensation build-up from poor airflow.
Fiberglass~90% light transmission; may allow more low-angle light; easier to cool than glass.Degrades under UV/dust/pollution, becomes brittle; very flammable.
Acrylic & polycarbonateAcrylic lasts up to 25 years, polycarbonate 10–15 years; lightweight; good light transmission; excellent heat insulation.Expensive; flammable.
