Left Coast Wholesale carries all the materials needed for successful year-round greenhouse growing. We offer multiple pre-cut and custom-cut options for greenhouse poly, ranging from standard clear covers to black-and-white covers designed for light deprivation greenhouses. Our offerings of greenhouse supplies include essential infrastructure materials like shade cloth, privacy fencing, and pond liners. When it comes to greenhouse supplies, Left Coast Wholesale has you covered inside and out!


40% Shade Cloth
Shade cloth can help plants grow faster and stay healthier by blocking 40% of light to retain cooler temperatures in extreme-heat environments. Constructed of high-density polypropylene, our shade cloth protects against wind, hail, and UV rays while resisting rips, tears, and fraying.

Sungrower Supply Privacy Fencing
Sungrower Supply Privacy Fencing is a durable poly screen fabric with a reinforced hem and grommets for easy installation. Measuring 75” wide x 300′ long, this privacy material is far more cost effective than building a redwood fence and will shield plants and property from public view.

Duraline Greenhouse Poly
A long-lasting covering that includes excellent light transmission, UV protection, and tensile strength durability. Duraline Greenhouse Poly keeps the plant’s environment warm, maintains better heat distribution, and reduces energy costs.

Custom-Cut Clear Greenhouse Poly
Left Coast Wholesale is proud to offer Custom-Cut Clear Greenhouse Poly with both woven and non-woven options and a variety of light diffusion levels to suit most weather and growing conditions.

Custom-Cut Blackout Greenhouse Poly
Custom-Cut Blackout Greenhouse Poly offers the ultimate in light deprivation and is made to last season after season. We offer woven and non-woven options in a variety of thicknesses for most cultivation needs.

White Ground Cover
The White Ground Cover is a strong, durable woven fabric that is resistant to weed penetration, helps to reflect light, and reduces heat. It’s especially useful when used in a greenhouse to help retain moisture on the soil, making sure newly planted seedlings won’t dry out.

Repair Tape
Our heavy-duty Repair Tape is ideal for mending tears in polyethylene greenhouse film and is designed to withstand adverse weather conditions for multiple seasons. Available in multiple sizes and coated with a high-tack acrylic adhesive intended for even the toughest repairs.
