When it comes to building a greenhouse, there are several materials to consider. First of all, durable options like aluminum or galvanized steel make popular choices for framing. Polycarbonate or glass make good roofing materials, while vinyl or polycarbonate panels work well for siding. Lastly, concrete or gravel can be used for greenhouse floors.
Note: In short, metal frames, especially galvanized steel, are your durability champions. Aluminum frames are a sleek runner-up. Wood and PVC frames are your short-term flings, and glass panels are your delicate darlings. Choose wisely, because a greenhouse is a relationship, not a one-night stand.
Greenhouse Components – and What’s Best…
Metal Frames: Like the Hercules of greenhouses, they’re sturdy and long-lasting. But they can rust if not properly maintained.
Aluminum Frames: Lightweight and rust-resistant, the James Bond of greenhouse materials. They’ll outlive your gardening enthusiasm. This pre-fab kit has a galvanized aluminum frame.
Wooden Frames: Classic, but high-maintenance. Expect a romance, not a long-term commitment. Wood’s like the drama queen of materials.
PVC Frames: Cheap and cheerful, but not exactly built to last. Think of them as disposable structures.
Galvanized Steel: Tough as nails, rust-resistant and ready for the apocalypse. Your plants might wither, but this frame won’t.
Polycarbonate Panels: Durable and UV-resistant, but prone to scratches. They’ll endure, but they’re not invincible. That said, they’re usually the best option for the roof and walls of a backyard greenhouse.
Glass Panels: Elegant and timeless, but fragile as a porcelain teacup. Handle with care if you want them to stick around.
What Material Can I Use for Greenhouse Panels?
Selecting the right greenhouse panels for your climate is crucial, but it’s not exactly rocket science. Let’s break down your covering options: glass, polycarbonate and plastic.
Note: Choose your building material wisely based on your climate and budget. Glass is for those with deep pockets and a penchant for traditional elegance. On the other hand, polycarbonate is the modern, practical choice. Plastic is for those who love a bargain but don’t mind the occasional heatwave struggle.
1. Glass: The OG of greenhouse materials, glass is like the wise old sage. It’s excellent at letting sunlight through and maintaining a stable temperature. However, it’s heavy, can break easily and isn’t the best insulator. So, it’s like wearing a tuxedo in a sauna – a bit excessive for some climates.
2. Polycarbonate: This modern wonder material is like the superhero of greenhouses. It’s lightweight, sturdy and insulates better (see a polycarbonate greenhouse here).Think of it like having a well-insulated jacket in the winter that keeps things cozy inside, except it’s not soft.
3. Plastic: Plastic is the budget-friendly option, but it’s also the high-maintenance friend. It’s lightweight, but it can degrade over time due to UV exposure. In other words, you may save money up front, but end up paying more in the long run for replacement panes.
Note: Now, let’s talk temperature regulation. Glass, while providing good insulation, doesn’t diffuse light well, leading to potential hot spots. Polycarbonate spreads light more evenly but can get too warm without proper ventilation. Plastic, on the other hand, is notorious for trapping heat, often necessitating more cooling measures.
Ideas for Greenhouse Flooring Materials – from Best to Worst
When choosing flooring materials for your greenhouse, consider options like concrete, gravel, or pavers. Concrete provides durability and easy maintenance, while gravel allows for good drainage. Pavers offer a versatile and aesthetically pleasing option that can be easily replaced if needed. Let’s cut to the chase and rank your options from best to worst for cleanliness and accessibility.
Concrete: It’s like the Rock of greenhouse floors – solid, dependable, and easy to clean. But it can be hard on your knees and doesn’t offer much cushioning.
Gravel: Adds some rustic charm, drains well and keeps your feet dry. However, it’s not the comfiest surface for long strolls.
Pavers: A touch of sophistication, easy to maintain, and provides good drainage. Like walking on a well-kept garden path.
Rubber Mats: The cushioned luxury of greenhouse floors. Gentle on your joints and easy to clean. Just avoid tripping on them.
Dirt or Soil: Seriously? It’s like planting your crops in your carpet. Messy, attracts pests and a nightmare to clean. Yes, it makes for a cheap floor build, but it’s a definite no-go.
Wood: This is how you invite termites to a garden party. Rot-prone, slippery when wet and not a friend of moisture. Hard pass.
In summary, concrete, gravel, pavers and rubber mats are your most reliable buddies for a clean and accessible greenhouse. Keep the dirt and wood out of the equation, unless you want your plants to stage a protest.
Greenhouse Coverings for Additional Plant & Seedling Protection:
- Polyethylene Film: This is a popular and cost-effective option. It comes in single or double layers and provides good insulation. UV-resistant films are available for longer durability.
- Fiberglass Panels: Fiberglass panels are lightweight, durable, and provide good insulation. Plus, they are resistant to UV radiation and typically have a longer lifespan.
- Shade Cloth: While not used as the primary cover, shade cloth is excellent for regulating light and temperature. It’s often used in conjunction with other cover materials.
- Polyvinyl Chloride (PVC): PVC films are easy to install, cost-effective and offer good insulation. You usually see them in single-season or temporary greenhouses.
- Shade Netting: While not a primary cover, shade netting is useful for providing shade to certain crops and regulating sunlight.
