Garden & Greenhouse Coverings
When you don't want your plants to experience the full force of Mother Nature, simply cover your garden with protective covers and nets. We have every kind of greenhouse plastic and fabric for tons of projects around work, home and garden. Provide cover to structures and open areas with the right greenhouse covering from Greenhouse Megastore.
Greenhouse Covering Materials for Healthier Plants
Owning a greenhouse isn't just about extending the growing season. It's about providing the appropriate environment. That's why we've stocked our shelves with all sizes and densities of quality coverings at the lowest prices!
Shop grow space coverings if you need plastic sheeting for greenhouse walls and roofs. We have polycarbonate sheets, acrylic and polyethylene film for all applications. Our greenhouse replacement film comes in various sizes and thicknesses, allowing you to purchase exactly what you need to protect your garden.
If you want to limit the amount of heat and sunlight plants are getting, use fabric greenhouse shade material. It greatly increases your climate control system efficiency, and is perfect for outdoor living spaces. You can care for the rest of your landscape as well with ground and plant covers for blocking weeds, protecting against frost, controlling erosion and much more.
Benefits of Greenhouse Coverings
Greenhouse coverings, whether plastics or fabrics, offer a range of performance-enhancing features that protect crops and optimize growing conditions:
- UV-stabilized materials resist degradation from sunlight, extending the lifespan of the covering while maintaining strength and clarity over time.
- Many advanced films include anti-condensate properties that prevent water droplets from forming and dripping onto plants; instead, moisture spreads into a thin layer that preserves light transmission and reduces disease pressure.
- Thermal coverings help regulate temperature by retaining heat during cooler periods and reflecting or diffusing excess solar energy during hot weather, improving climate stability inside the structure.
- Specialized options such as IRAC (Infrared Anti-Condensate) thermal films combine heat-retention technology with anti-drip performance to further enhance light penetration and minimize humidity-related disease.
For growers who require strict photoperiod control, blackout and light-deprivation plastics block outside light entirely, enabling precise flowering schedules and vegetative cycles. These coverings often incorporate reflective layers that also help manage heat, keeping interiors cooler while ensuring complete darkness when needed.

Choosing the Right Greenhouse Covering
Selecting the right greenhouse covering depends on your crops, climate, and production goals. Growers in high-sun regions may prefer films with strong UV protection or light-diffusing properties to reduce plant stress, while cooler climates often benefit from thermal or IR-retentive coverings that help maintain consistent temperatures. Specialty crops, such as those requiring strict flowering cycles, may call for blackout films that provide total light control, whereas moisture-sensitive plants thrive under anti-condensate films that reduce dripping and disease pressure.
Different materials offer unique advantages: clear films maximize direct light for early-season growth, diffused films promote uniform canopy development, woven fabrics offer durability and shade, and multi-layer plastics provide combinations of insulation, strength, and controlled transmission.
By matching technical features, like light diffusion, thermal retention, anti-drip coatings, and blackout capabilities, to your specific cultivation needs, you can create an optimized environment that supports healthier plants and more predictable yields.
FAQs On Garden & Greenhouse Coverings
What type of greenhouse covering is best for my climate?
Warmer regions often benefit from light-diffusing or heat-reflective films, while cooler climates typically need thermal or IR-retentive coverings to maintain stable temperatures. Choose based on sunlight intensity, seasonal swings, and crop needs.
How long do greenhouse plastics and fabrics last?
Most UV-stabilized coverings last several seasons, with many premium films rated for 3–5 years or more. Lifespan depends on material type, thickness, and exposure to weather.
Do I need anti-condensate (AC) film?
If moisture or dripping is a concern, or if fungal disease is common in your greenhouse, AC films help by preventing droplet formation and preserving higher light transmission.
When should I choose blackout or light-deprivation material?
Blackout coverings are ideal for crops that require strict dark periods to trigger flowering or specialized growth cycles. They completely block external light and help you control photoperiods regardless of the season.
