A backyard greenhouse can be a game-changer for gardeners and growers, extending the growing season, protecting plants from harsh weather, and even providing a space for year-round cultivation. But one of the most critical decisions when setting up a greenhouse is choosing the right material. The best greenhouse material depends on your climate, budget, and whether you’re gardening for fun or planning to grow crops for sale.
Choosing the Right Greenhouse Material
Selecting the right greenhouse material involves evaluating insulation, durability, light transmission, and cost. Below are the most common greenhouse covering options, their benefits, and their ideal applications.
Glass Greenhouses: Classic and Long-Lasting
Best for: Mild to moderate climates, serious growers, long-term investment
Pros:
-
Excellent light transmission (90%+)
-
Long-lasting (can last decades with proper maintenance)
-
Aesthetic and traditional appeal
-
Resistant to UV degradation
Cons:
-
Expensive initial cost and installation
-
Heavy and requires a strong frame
-
Fragile and can break from hail, storms, or accidental impact
Who should choose glass? If you are serious about long-term gardening or selling crops and live in a stable climate without extreme hailstorms, a glass greenhouse may be the best investment. However, it’s not ideal for areas prone to high winds or heavy snow unless reinforced.
Polycarbonate Panels: The Balance of Durability and Insulation
Best for: Cold climates, year-round growing, high-wind or hail-prone areas
Pros:
-
Stronger than glass (shatter-resistant and impact-resistant)
-
Good insulation, reducing heating costs in cold climates
-
UV-resistant and can last 10-20 years
-
Lightweight, making installation easier
Cons:
-
Lower light transmission than glass (around 80%)
-
Can yellow over time if not UV-coated
-
More expensive than polyethylene film
Who should choose polycarbonate? If you want a durable, energy-efficient greenhouse that will withstand extreme weather conditions, polycarbonate is a great choice. It’s ideal for serious growers looking to maintain a controlled growing environment year-round.
Polyethylene Plastic Film: Affordable and Versatile
Best for: Hobby growers, seasonal use, budget-conscious gardeners
Pros:
-
Cheapest greenhouse covering option
-
Good light diffusion, reducing plant scorching
-
Flexible and easy to install
-
Can be used in hoop-style or framed greenhouses
Cons:
-
Not as durable (lasts 3-5 years, depending on thickness and UV treatment)
-
Can tear easily in strong winds
-
Requires replacement more frequently than glass or polycarbonate
Who should choose polyethylene? If you are looking for an affordable and easy-to-install greenhouse covering for home gardening or seasonal growing, polyethylene film is a cost-effective solution. It works well in mild climates and for growers who don't need a permanent structure.

-
Highly durable and resistant to extreme weather (wind, snow, hail)

Fiberglass Panels: Strong but Less Common
Best for: Windy areas, those looking for a lightweight alternative to glass
Pros:
-
Strong and impact-resistant
-
Good light diffusion to prevent plant burns
-
Lightweight and easy to install
-
Moderate insulation properties
Cons:
-
Can discolor and degrade over time without UV protection
-
Less transparent than glass and polycarbonate
