Grow1 Greenhouse Shade Cloth - Black - 50% Light Deprivation - 20 x 48 ft

Knitted 50% Light Reduction for Greenhouse Cover - 20 x 48 ft

Too much direct light can stress plants and push greenhouse temperatures up. This black shade cloth blocks 50% of light and is knitted from high-density polyethylene (HDPE), so it can be drawn over a structure to tone down exposure while still letting air move through the fabric. The material is made with UV protection for outdoor weather.

At 20 x 48 ft, this roll suits a mid-sized greenhouse or hoop structure, or a grower who wants to cover one section of a larger site. Smaller and larger sizes are offered in the same line for other layouts.

Key Features & Benefits

• 50% light reduction — lowers light intensity reaching plants under the cover.
• Knitted HDPE fabric — built for repeated seasonal use outdoors.
• UV protection — helps the fabric hold up in sun and weather.
• Airflow through the weave — allows ventilation while shading.
• Black colour — a neutral cover that works over most structures.

Who Should Use Grow1 Greenhouse Shade Cloth

Home gardeners and licensed commercial growers who need to reduce light and heat in a greenhouse, or who manage light exposure during vegetative growth or flowering, will find this cloth useful.

Frequently Asked Questions

Q: What does 50% light deprivation mean?
A: It means the fabric is designed to block about half of the light that would otherwise reach the plants below. The rest passes through the knit. This lowers light intensity and can reduce heat build-up.

Q: What is HDPE?
A: HDPE is high-density polyethylene, a strong plastic used for durable outdoor fabrics. Here it is knitted into a flexible cloth. It resists weather better than many natural fabrics.

Q: Does shade cloth allow airflow?
A: Yes, the knitted structure lets air move through, which helps limit trapped heat. Airflow also depends on how the cloth is installed and how much open space surrounds it.

Q: How is shade cloth different from solid plastic sheeting?
A: Shade cloth is open-weave, so it passes some light and air. Solid sheeting blocks airflow and traps moisture and heat. Choose cloth when you want to reduce light while keeping ventilation.

Q: How do I install it?
A: Stretch it over the frame or structure and secure it along the edges with clips, ties or fasteners suited to your setup. Keep it taut to limit flapping in wind.
