• Gutter height : 189cm

Weight

• Greenhouse only : 300kg
• Tank with vertical growing system loaded with water : 700kg
• Floor and permaculture beds : 200kg

Colour

• Standard finish : ebony black lacquered aluminium RAL 9005

Optimal operating temperature

• From -5°C to 40°C with the appropriate equipment and recommendations

Power supply

• Single-phase : 230V 50Hz
• Consumption : less than 60W

Connectivity

• Sigfox if available, Wifi or Ethernet

Wind resistance

• Usually withstands up to 100 km/h
• In the case of frequent strong winds, adaptations are essential (reinforced anchoring, adapting the greenhouse orientation, installing windbreak barriers, etc.)

Snow and hail resistance

• Withstands between 50 and 75kg/m². It is strongly recommended to clear snow from the greenhouse roof
• Usually withstands heavy rain and moderately sized hailstones (diameter between 5 and 20 millimetres)
