A metallic greenhouse in Kenya is a plant house made of metal frames, bolted and screwed together to form a canopy covered using a U.v treated greenhouse polythene of gauge 800 to 1000 equivalent of 150 to 200 microns with a lifespan of between 3-5 years or and anti-insect nets for ventilation, this creates a microclimatic condition favourable for optimum plant growth in all seasons. The greenhouse is designed with a top vent or tunnel shape design and is partially covered with an insect net.

Durability and lifespan of metallic greenhouse in Kenya
Metallic greenhouses in Kenya last 8- 15 years depending on the region. In coastal provinces like Mombasa and Kilifi the metallic frames tend to rust faster due to the salty humid conditions.
The greenhouse polythene 200 microns UV treated has a manufacturer guarantee of 3 years and can be used for 6 years.
