60-70% Shade Cloth Heavy Duty Knitted Mesh Tarp 12x20FT - Durable

Our review of this 12x20ft shade cloth finds it is best for gardeners, patio owners, and anyone needing reliable sun protection for plants or outdoor spaces; the single biggest reason to buy is its combination of heavy duty 100% HDPE construction and effective 60%-70% light blockage that reduces heat while still allowing plant growth. Installation is straightforward and customers report measurable temperature drops under the tarp, so the product works as a practical, long-lasting shading solution rather than a short-term cover.

Key Features

• Light blockage: Blocks 60%-70% of direct sunlight to prevent plant sunburn while still permitting enough light for growth.
• Material strength: Made from 100% new high density polyethylene (HDPE) with a fine 0.16in x 0.16in grid that resists tearing and holds shape under tension.
• Weather resistance: UV resistant for up to five years and constructed to withstand temperature extremes without rapid degradation.
• Reinforced edges: Double-stitched sides and wide polyester webbing along edges add strength and reduce fraying at attachment points.
• Grommet hardware: Rust-free aluminum grommets with 0.5in inner diameter are spaced every 20in for convenient, secure tie-downs.
• Versatility: Suitable for patios, greenhouses, pool decks, kennels, dump trucks, and general garden shade applications.

Who It's For

This shade cloth is aimed at home gardeners, small-scale growers, and homeowners with patios, pergolas, or pool areas who need a sturdy shade solution that balances sun reduction and plant light needs. It is also useful for hobby livestock or dog kennels where airflow and bug resistance matter.

People who should look elsewhere include buyers who require a fully waterproof tarp or a complete blackout material; this knitted mesh is designed for shade and air flow rather than rainproof covering. Also, if exact edge-to-edge precision is critical, note there can be up to a 4in manufacturing tolerance on dimensions.

Pros & Cons

Pros

• Durable 100% new HDPE construction offers long service life and tear resistance.
• Effective temperature control and shade, with customers reporting noticeable ambient cooling.
• Easy to install using evenly spaced rust-free aluminum grommets and reinforced edges.
• Multi-purpose use across garden, patio, and worksite needs for plants and outdoor areas.

Cons

• Not waterproof, so it will not protect against heavy rain or provide a sealed cover.
• Size tolerance up to 4in edge-to-edge means exact fit for some framing setups may require adjustment.

Specifications

Our Verdict

This 12x20ft heavy duty knitted mesh shade cloth is a practical purchase for gardeners and homeowners who want durable, breathable shade that noticeably lowers ambient temperature and protects plants from sunburn. Its robust HDPE build, reinforced edges, and well-spaced grommets deliver reliable value for outdoor shading tasks, though buyers needing waterproof coverage should choose a different product.
