How to Build a Shade Net House for Farming: A Step-by-Step Guide

A shade net house is one of the most effective structures for protecting crops from excessive sunlight, pests, wind damage, and unpredictable weather. For Kenyan farmers growing vegetables, herbs, tree seedlings, ornamentals, and nursery crops, a well-constructed shade net house creates a controlled microclimate that improves growth, increases yields, and reduces losses.

This guide explains how to design, build, and maintain a shade net house, how to choose the right netting, and the benefits plants gain from shade-house cultivation.

Why Shade Net Houses Matter in Kenyan Farming

A shade net house creates an environment that balances sunlight, humidity, and airflow—critical factors for crop performance in warm regions.

Key benefits include:

Reduced heat stress and sunburn on crops
Controlled light penetration for healthy plant development
Protection from birds, insects, and large pests
Shielding against wind, hail, and heavy rains
Improved seedling survival and faster establishment
Lower water evaporation and more stable moisture levels

For both smallholder and commercial farms, shade net houses offer cost-effective protection and consistent production year-round.

Choosing the Right Shade Net for Your Crops

Selecting the correct net type determines the success of your structure. Consider:

1. Shade Percentage

30%–50%: Vegetables, herbs, tomatoes, peppers
50%–75%: Seedlings, ornamentals, potted plants
75%–90%: Sensitive crops, nurseries, and hardening areas

2. Colour Options

Green: General-purpose shade
Black: Stronger UV protection
White: Better light diffusion for nurseries
Aluminet (silver): High performance for heat management

3. Material Quality
Use UV-stabilized HDPE agricultural shade nets for long life and consistent performance.

Step 1: Planning the Structure

Before construction:

Choose a flat, well-drained site
Ensure access to irrigation and pathways
Determine the size based on crop volume
Plan for adequate ventilation and workable entry points

Basic structure components:

Vertical posts (wood, steel, or treated poles)
Horizontal beams
Shade net roofing and side panels
Fasteners (wire, clips, ropes, nails)
Ground anchors

Step 2: Constructing the Frame

Marking and Digging:

Outline the perimeter using string and pegs
Dig post holes 1–2 feet deep, depending on wind exposure

Setting Vertical Posts:

Use treated timber or metal poles
Ensure all posts stand upright and evenly spaced
Backfill with soil and compact firmly

Adding Horizontal Supports:

Attach beams across the top of the posts
Strengthen the frame with diagonal bracing for stability

This provides a strong skeleton for the shade net.

Step 3: Fixing the Shade Net

Proper installation ensures durability and long-term effectiveness.

Roof Fixing:

Spread the shade net over the structure
Secure using binding wire, cable ties, net clips, or rope
Keep tension even to avoid sagging during rain or wind

Side Covering:

Cover side walls with matching shade net material
Leave openings or roll-up sections for ventilation
Reinforce corners and entry points with extra fasteners

Anchoring:

Use ground pegs or wire anchors to secure the bottom edges
Prevent lifting during windy conditions

Step 4: Adding Doors and Access Points

Install simple wooden or metal frames with hinged doors
Cover doors with the same net material for consistency
Ensure easy movement of workers and equipment

Step 5: Irrigation Setup

Shade houses work best with controlled watering systems:

Drip irrigation for vegetables and herbs
Misters or foggers for nurseries and ornamentals
Overhead sprinklers for large installations

Uniform irrigation improves plant performance and reduces water loss.

Maintenance and Care of Your Shade Net House

To maintain a functional structure:

Inspect nets monthly for tears
Tighten loose cables or ties
Replace damaged sections immediately
Keep the inside clean and weed-free
Ensure proper airflow to prevent fungal issues

With good care, quality shade nets can last 4–6 years in Kenyan conditions.

Crops That Perform Best Under Shade Nets

Vegetables:
Tomatoes, peppers, spinach, sukuma wiki, lettuce

Nurseries and Seedlings:
Fruit seedlings, forestry, ornamentals, bedding plants

Herbs:
Mint, coriander, basil, parsley

Flowers:
Roses, chrysanthemums, potted ornamentals

Common Mistakes Farmers Should Avoid

Using the wrong shade percentage for the crop
Building on uneven ground that floods
Installing nets without proper anchoring
Allowing sagging areas that collect rainwater
Ignoring ventilation requirements
Using non-UV-stabilized nets that deteriorate quickly
