Heavy-Duty UV Protection for Plants & Structures
 
Beat the Heat Without Losing the Light!
 
If you’re growing in a high-heat environment, white shade cloth is one of the smartest investments you can make for your greenhouse or high tunnel. Our 50% white shade cloth blocks half the incoming sunlight while reflecting a significant portion of solar radiation away from your structure — keeping temperatures noticeably cooler than black shade cloth at the same shade rating.
This isn’t a one-season cover. Our shade cloth is built from high-density polyethylene monofilament and fully UV treated, giving it the durability to stand up to years of intense sun exposure without breaking down, cracking, or losing its flexibility.
 
Why White? Why 50%?
Color matters more than people realize when it comes to shade cloth. Black absorbs heat — white reflects it. That reflected light doesn’t just disappear; it diffuses, scattering sunlight in multiple directions so your plants receive softer, more even light coverage instead of harsh, direct rays. The result is a cooler growing environment, reduced sunburn risk for sensitive crops, and more consistent growth across your whole planting area.
 
At 50% shade, you’re allowing exactly half of available sunlight through — making this the ideal choice for:
• Greenhouses and high tunnels in hot climates
• Shade-loving vegetables, flowers, and transplants
• Nurseries and seedling houses needing light diffusion
• Protecting young or heat-sensitive plants during summer peaks
• Outdoor garden areas, patios, and livestock shelters

Built to Last — Not Just for One Season
This shade cloth is engineered for longevity. The knitted monofilament construction resists tearing, stands up to wind and rain, and won’t deteriorate even under the most punishing summer sun. It’s also breathable — hot air moves through instead of building up underneath, improving ventilation and reducing the overall temperature load inside your greenhouse.
And because it’s knitted rather than woven, you can cut it to any custom size without the edges fraying or coming apart. No hemming required.
 
How to Size Your Shade Cloth
For greenhouse and high tunnel applications, measure hip-to-hip across your structure rather than just the width of the frame. The cloth should drape down each side for proper coverage.

Installation Tips
Every order ships with grommets, so you’re ready to hang it right out of the box. For additional securing options, shade cloth can be installed two ways:
 
• Wiggle wire and channel — the industry-standard method for a drum-tight, professional fit; simply press the wire into the channel over the edge of the shade cloth; available in our store
 
Frequently Asked Questions
Does this shade cloth come with grommets?
Yes! Every order includes grommets so you’re ready to install right away. 
 
Can I cut it to a custom size?
Yes — cut it to any dimension you need and the edges will hold without fraying or raveling.
 
Is white shade cloth really cooler than black?
Yes. White reflects solar radiation rather than absorbing it, which meaningfully reduces the temperature underneath compared to black shade cloth at the same shade percentage. It’s the go-to choice for growers in hot, high-sun climates.
 
What plants do best under 50% white shade cloth?
Lettuce, spinach, herbs, transplants, flowers, orchids, and any crop that benefits from filtered light and reduced heat stress. It’s also widely used for nursery stock, seedling propagation, and protecting young plants through summer.
