Shade Net Selection: Understanding Shade Percentages for Different Growing Conditions

Choosing the right shade net depends on the crop, growth stage, climate, sunlight, and growing environment. This guide explains shade percentages and key factors like material, UV protection, colour, GSM, and size to help you select the right shade net.

Introduction

Choosing the right shade net is not simply about picking the highest or lowest percentage. The right level depends on the crop, growth stage, climate, sunlight and where the net will be used.

A 50% shade net is designed to provide about 50% shade under the stated measurement conditions. Higher levels such as 75% reduce more incoming light. Common shade levels include 30%, 35%, 50%, 75% and 90%, but no single level is right for every crop.

The goal is simple: reduce excess sunlight and heat without blocking more light than the crop needs.

What Does Shade Percentage Mean?

Shade percentage tells you how much incoming sunlight a shade net is designed to reduce. A 35% shade net allows more light through than a 75% shade net, while a 90% shade net provides much stronger shading.

The table below gives a simple reference for common shade levels. These are general levels, not fixed recommendations for every crop.

The actual light reaching a crop can also change with season, location, sunlight intensity, net colour, fabric construction and installation.

How to Choose the Right Shade Percentage?

Start with the crop's light needs. Then consider the climate, season, growing structure and sunlight at the site.

30–35% Shade

Lower shade levels keep more light available while providing some protection from strong sunlight and heat.

They may be considered for:

  • High-light crops
  • Selected vegetables
  • Young plants
  • Areas with strong sunlight
  • Applications needing moderate shade

50% Shade

A 50% shade net gives a more balanced level of shading and is commonly used for horticulture, nurseries and selected protected-growing applications.

It may suit:

  • Nurseries
  • Selected vegetables
  • Foliage plants
  • General horticultural use
  • Crops exposed to strong summer sun

The exact requirement still depends on the crop and growing conditions. An ICAR study on dragon fruit, for example, found that 50% shade nets reduced canopy temperature under the tested summer conditions. That result is specific to the crop and setup and should not be treated as a rule for every crop. (icar.gov.in)

75–90% Shade

Higher shade levels provide much stronger light reduction.

They may be suitable for:

  • Shade-loving plants
  • Selected ornamental crops
  • Some floriculture applications
  • Specialised shading needs

Very high shade levels, such as 90%, can also be used in non-crop applications such as livestock, poultry, construction and vehicle shading.

How Growing Conditions Change Shade Net Selection?

The same shade net can give different results in an open field, nursery or greenhouse.

The table below shows the main conditions that should be considered before selecting the shade level.

Growing ConditionMain ConcernWhat to Consider
Open fieldStrong sunlight and heatCrop needs and local climate
Greenhouse/polyhouseHeat and light controlExisting covering and ventilation
NurseryYoung-plant protectionGrowth stage and light needs
FloricultureCrop-specific light needsPlant type and growing system
OrchardSun and heat stressCrop age and local conditions


Open-Field Farming

In open fields, shade nets can reduce strong sunlight and heat while allowing useful light to reach the crop.

Selection should consider the crop's light needs, local climate, season, sunlight intensity and heat stress.

A shade level that works well in one region may not give the same result in another.

Greenhouses and Polyhouses

Greenhouses and polyhouses already change the amount of light and heat around the crop. Adding shade netting changes that environment further.

Before choosing a shade net, consider the existing covering, ventilation, temperature, sunlight, crop type and season.

Nurseries

Young plants need protection from strong sunlight but still need enough light to grow well.

Shade needs can also change during propagation and hardening. A level that works for one stage may be too strong or too weak for another.

Floriculture and Orchards

Flowers, ornamental plants and young orchard plants can have different light needs.

Selection should follow the crop, plant age, climate and growing conditions rather than a fixed percentage.

What Else Should You Check Besides Shade Percentage?

Shade percentage is important, but it is only one part of shade net selection.

Crop and Growth Stage

A seedling, mature crop and flowering plant may not need the same amount of light.

Choose the net for the growth stage as well as the crop itself.

Colour and Material

Black, green and white shade nets can create different light environments. The right choice depends on the crop and intended use.

HDPE is commonly used for agricultural shade net fabric because it combines strength with outdoor durability.

Bubna's shade net range uses HDPE construction and UV stabilisation and is available for agricultural, gardening and outdoor applications.

UV Stabilisation

Outdoor shade nets stay exposed to sunlight for long periods. UV stabilisation helps the material handle prolonged sun exposure and maintain its physical performance.

Size and GSM

Measure the structure before choosing the shade net size. Also consider fixing points, overlaps and tensioning.

GSM means grams per square metre and shows the fabric weight. It can help compare products, but it should not be the only measure of quality. Material, weaving, strength and UV protection also matter.

Common Shade Net Selection Mistakes

Several simple mistakes can reduce the value of an otherwise suitable shade net.

Choosing Only by Price

A lower-priced product may not offer the required shade level, strength or outdoor durability.

Assuming More Shade Is Always Better

More shade means less light reaches the crop. That helps only when the crop actually needs less light.

Ignoring Growth Stage

Light needs can change as a plant grows. A net chosen for seedlings may not be right for mature plants.

Overlooking UV Protection

Outdoor shade nets should be checked for UV stabilisation and suitability for long-term sunlight exposure.

Choosing the Wrong Size

A poorly sized net can leave gaps, create excess fabric or make installation difficult.

The table below gives a quick check for the most important selection points.

Check Questions to Ask
Shade percentage
Does the crop need this level of light reduction?
Crop stage
Is the net for seedlings, mature plants or flowering?
Climate
How strong are sunlight and heat at the site?
Material
Is the fabric suitable for outdoor use?
UV protection
Is it made for long sun exposure?
Size
Will it cover the structure properly?
GSM
Is the fabric weight suitable for the application?

How to Choose a Shade Net for Your Application?

Before selecting a shade net, check the complete specification instead of looking at the percentage alone.

Review:

  • Shade percentage
  • Crop and growth stage
  • Material
  • UV stabilisation
  • Colour
  • Size
  • GSM
  • Installation requirements

Bubna's shade net range provides information on available material, shade levels, colours and sizes.

Conclusion

Choosing the right shade net starts with the crop and growing conditions, not simply the percentage printed on the product.

Lower levels such as 30–35% may suit crops that need more light, while 50% can provide a balanced level of shading for many horticultural uses. Higher levels such as 75% or 90% are better suited to plants or applications that need stronger shade.

The final choice should also consider crop stage, climate, colour, HDPE shade net fabric, UV protection, GSM, size and installation.

The best shade net is not the one with the highest percentage. It is the one that gives the right amount of protection for the crop and the place where it is being used.

FAQ's

Q.1. What does shade percentage mean in a shade net?

Ans. Shade percentage tells you the rated amount of incoming sunlight that the net is designed to reduce. A 50% shade net is designed to provide about 50% shade under the stated measurement conditions.

Q.2. Which shade percentage is best for vegetables?

Ans. There is no single best percentage for every vegetable. The right choice depends on the crop, climate, season, growth stage and growing structure.

Q.3. Is 50% or 75% shade better?

Ans. Neither is always better. A 50% shade net allows more light through, while 75% provides stronger shading. The crop and growing conditions should decide the choice.

Q.4. How do I choose the right shade net for my crop?

Ans. Start with the crop's light requirement. Then consider sunlight, climate, season, growth stage and growing structure before choosing the shade percentage and material.
