Shade Cloth: How Much Shade Do You Actually Need?
Shade cloth is knitted, UV-stabilized polyethylene that filters sunlight — cooling the plants, people, and animals underneath while still letting air and light through.
The whole decision comes down to one number: shade percentage, from 30% (light) to 90% (near-total). Pick that for what you're covering, then choose color and finish. That's what the Selector does.
Shade percentage is simply how much sunlight the cloth blocks — a 50% cloth blocks half the light and passes the other half. Too much shade starves sun-loving plants; too little leaves shade plants, people, or livestock exposed. Here's how the range maps to common jobs.
Sun-loving vegetables like tomatoes and peppers, hardening off seedlings, and taking the edge off harsh afternoon sun.
The all-rounder — bedding plants, nursery container stock, and general greenhouse shading with moderate cooling.
Shade-loving plants, ferns, ornamentals, and orchids — plus comfortable cover over a patio or seating area.
People areas like patios, carports, and pergolas, livestock and kennel shade, and heat-sensitive plants in hot climates.
Deep shade, privacy screening, and the most heat and UV reduction — for the densest cover you can get.
Why Knitted, Not Woven
All of this shade cloth is knitted from 100% UV-stabilized polyethylene with a lock-stitch construction — and that matters more than it sounds. Woven shade cloth frays and unravels the moment you cut it, so every piece needs hemming. Knitted lock-stitch doesn't run when cut, so you can size a panel to your exact opening with nothing more than scissors. It's also lighter and more tear-resistant, and the UV stabilization means it holds up to years of direct sun without going brittle.
Pick Your Color
Color is more than looks. Black is the standard — durable, economical, and the most common choice for nurseries and general use. Green blends into a garden or landscape, which is why it's popular for residential cover. White reflects heat rather than absorbing it and diffuses the light that passes through, so it runs cooler underneath — the choice for greenhouses where you want cooling and even light without heat buildup. For patios and architectural structures, designer tones like mocha, ultra-tan, steel grey, and forest green give you the same performance with a finished look.
Finished or Unfinished
Both come in commercial roll widths from 6′ up to 50′. Finished cloth has fully taped edges with grommets every two feet, so it's ready to hang and tie down — the right pick for permanent panels and structures where the edges take strain. Unfinished cloth has raw cut edges, which is what you want when you're cutting to custom shapes, lining a frame, layering for extra density, or covering a large area where you'll attach it your own way. Because the knit won't unravel, raw edges hold up fine either way.
Get the Percentage Right First
Color and finish are easy to change your mind on — shade percentage isn't. Over-shade sun-loving vegetables and they stretch and underproduce; under-shade ferns, orchids, or a patio and you haven't solved the problem. Decide what's living or sitting under the cloth, match the percentage to it, and choose color and finish from there.
Quick Selection Checklist
- 1. Start with shade percentage: 30–40% for sun-loving vegetables, 50% for general nursery and greenhouse, 60% for shade plants, 70–80% for people and livestock, 90% for deep shade and privacy
- 2. Don't over-shade sun crops or under-shade shade plants — match the % to what's underneath
- 3. Pick color for the job: black for durability and standard use, green to blend into a landscape, white to reflect heat and diffuse light in a greenhouse
- 4. Choose finished (taped edges, grommets every 2 ft) for hang-and-go panels, or unfinished (raw cut edges) for custom cutting and large coverage
- 5. Knitted lock-stitch won't unravel when cut, so you can size any piece without hemming
Popular places to start: 30% black for vegetables, 50% black for general nursery and greenhouse use, 60% green for gardens, 70% black for patios and livestock, and 90% black for maximum shade and privacy — all knitted, UV-stabilized, and shipped free.
