What Is a Greenhouse Construction Kit?
Greenhouse Construction Kit is a set of materials for constructing a greenhouse structure. They include galvanized steel, UV-treated polythene, insect and shade nets, and irrigation kits. For wooden greenhouse structures, wooden poles are used instead of galvanized steel pipes.
Greenhouse Materials: Requirements for Constructing Greenhouses

When constructing a greenhouse, the choice of greenhouse kits affects durability and performance:
1. Frame Materials
- Wooden Frames: Cheap and easy to source but require treatment against rot and insects.
- Galvanized steel: stronger and more durable, often last over 10 years.
- Tapping Screws: for attaching steel frames together to form a skeleton greenhouse structure.
- Steel Profiles and Wires: holds the greenhouse polythene or net to the structure.
2. Greenhouse Covering Materials
- Polythene Sheets: Common for affordable kits, UV resistant, and flexible.
- Polycarbonate Panels: More expensive but provide excellent light diffusion and durability.
3. Other Accessories
- Drip Irrigation Kit: ideal for efficient crop irrigation and optimal growth. Conserves water and maintains consistent moisture.
- Insect & Shade Nets: Protect crops from pests and manage sunlight.
Greenhouse Structure Costs in Kenya
The cost of greenhouse construction in Kenya varies by size, material, and features:
- Low-cost basic kits: KES 60,000–130,000 for simple wooden greenhouses.
- Mid-range metallic greenhouses: KES 200,000–600,000 depending on size.
- High-end polycarbonate greenhouses: KES 500,000 up to over KES 1,200,000.
Extra Greenhouse Farming Costs
Extra costs include labour, irrigation systems, water tanks, seedlings, crop support and installation.
Investing in quality greenhouse materials lowers maintenance and leads to continuous top production.
Choosing the Right Greenhouse Construction Kit
Selecting the best greenhouse construction kit depends on your crop and scale:
· Smallholders: 8 m x 15 m kits are common starter sizes.
· Commercial Farms: 16 m x 30 m or larger with polycarbonate or advanced ventilation.
Also consider your region’s climate when choosing a greenhouse to venture in. Ventilated designs help in hot areas, while enclosed tunnel designs retain warmth in cooler zones.
Step-by-Step Greenhouse Construction Process
1. Site Preparation: Level ground and clear debris.
2. Frame Assembly: Connect main supports and arches.
3. Cover Installation: Stretch UV-treated polythene or panels over the frame.
4. Irrigation & Ventilation: Install drip lines and roll-up side vents.
Irrigation & Climate Control Systems
Greenhouse irrigation plays a major role in productivity:
· Drip Irrigation: Reduces water use by up to 50% compared to traditional irrigation.
· Ventilation & Shade Nets: Reduce heat stress and prevent fungal issues.
Modern greenhouses sometimes include misting systems for seedlings or foggers for humidity management.
