Types of Greenhouses Available in Kenya

At Irrihydrosol Ltd, we offer two main types of greenhouses to cater for customer’s unique needs and specifications:

1. Galvanized Steel Greenhouses

Galvanized steel greenhouses are popular for their durability and long life compared to other materials like wood. Here are some reasons as to why the galvanized steel greenhouses are considered superior:

They are weather resistance: The zinc coating protects the structure from moisture and other harsh atmospheric conditions.
UV treated polyethene cover: UV treatment on the cover protects the crops from harmful radiation.

We offer two main types of greenhouses:

i) Tunnel Greenhouses

These green houses are cost effecting and takes short time to set up making them ideal for both small and medium scale farming. Here are the main advantages of using the tunnel greenhouse:

Mobility and location flexibility: The structure can be moved from one location to another to serve the farmers unique needs.
Quick to install: They take much less time to set up and install which comes handy during relocation or moving to and from leased farmlands.

Cost effective: These greenhouses are budget friendly making them affordable for small scale and medium farming operations.

ii) Open Ventilated Greenhouses

These are greenhouses designed to allow natural airflow through strategically installed ventilation systems. This type of greenhouse is especially ideal for high temperature conditions like in most Kenya farming regions, where ample air circulation is crucial for plant growth.

Main Features in an Open Ventilated Greenhouse:

Efficient ventilation system: To allow good air circulation for regulation of temperatures inside the greenhouse.
UV treated cover and optional shade net: These are essential to protect the crops from external interference, direct sunlight, and for the manipulation of temperatures.

Insect net cover (Optimal): Allowing optimal flow of air while keeping pest and diseases away.

2. Wooden Greenhouses

Wooden greenhouses are considered cost effective and aesthetic. Wood is also a locally available material making it easy to acquire and replace. Here are some advantages to consider when going for a wooden greenhouse:

A good insulator: Wood is a good insulator helping maintain optimal temperatures within the greenhouse, benefiting the plant.
Wooden greenhouses are sustainable: Since wood is a renewable resource, wooden greenhouses are considered environmentally friendly.
Aesthetically pleasing: Wood can enhance the overall appeal of a garden due to its capability to blend in naturally with its surroundings.
Durable: When taken care of, wooden greenhouses can last decades.
Customizable: Wood is easy to work with, allowing customization of greenhouses to serve the farmer’s unique needs.
Environmentally friendly: Since wood occurs naturally, there are no health threats to humans and the environment compared to other materials like plastic.

Giving the frame a solid base and structural support.
Keeps the structure stable against soil erosion and strong winds.
Provides years of stability and performance.

3. Insects and Bird Nets

Reduce expenses need for chemical pesticides.
Maintaining protection for high-value crops from threats.
Naturally protect the crops against pests.

4. 200 Micron UV-Treated Polythene Cover

Protects plants from harmful UV rays that may damage the crops.
Allows just enough access of light.
