Choosing Your Backyard Greenhouse: A Simple Buying Guide
A backyard greenhouse is a fantastic addition for any gardening enthusiast. It lets you grow plants earlier, later, and even exotic ones! But picking the right one can feel overwhelming. This guide breaks down what you need to know.
1. Key Features to Look For
When shopping, look closely at these features. They make a big difference in how well your greenhouse works for you.
Size and Space
- Footprint: Measure your backyard space first. Greenhouses come in small cold frames or large walk-in structures.
- Height: Do you want to stand up inside comfortably? Taller greenhouses offer more room for climbing plants.
Ventilation
Good airflow prevents overheating and plant diseases. Look for:
- Roof Vents: These let hot air escape easily. Automatic openers are a huge plus!
- Side Vents or Louvers: These help draw in cooler air from the bottom.
Door Style
Consider how you move in and out. Sliding doors save space. Hinged doors offer a wider opening for moving big pots.
2. Important Materials Matter
The materials used determine how long your greenhouse lasts and how well it insulates.
Framing
- Aluminum: This is the most popular choice. It is light, strong, and will not rust. Good quality aluminum frames last for years.
- Galvanized Steel: Stronger than aluminum, often used for larger, heavy-duty units. It resists corrosion well.
- Wood: Looks beautiful, but requires regular sealing and maintenance to prevent rot.
Glazing (The Covering)
This is the clear part that lets light in. Quality varies greatly:
- Polycarbonate Panels: These are the best choice for most backyards. They are tough, lightweight, and insulate better than glass. Twin-wall polycarbonate is especially good at keeping heat in.
- Glass Panels: Offers the clearest view and best light transmission. However, it is heavy, breaks easily, and insulates poorly unless it is tempered or double-paned.
- Polyethylene Film (Plastic Sheeting): Cheapest option, often used for temporary or hoop-style houses. It needs replacing every few years.
3. Factors That Improve or Reduce Quality
Not all greenhouses are built the same. A few details separate a cheap kit from a lasting investment.
Quality Indicators (Good)
- Sturdy Base: A solid foundation (like a concrete slab or treated wood perimeter) anchors the structure against wind.
- Thick Glazing: Thicker polycarbonate (6mm or more) or tempered glass offers better insulation and durability.
- Hardware: Stainless steel screws and strong locking mechanisms mean the structure stays tight over time.
Quality Reducers (Bad)
- Thin Aluminum Frame: Frames that feel flimsy when you touch them might buckle in strong winds or under snow load.
- Poor Seals: If panels don’t fit tightly, cold air leaks in, and you waste money heating the space.
4. User Experience and Use Cases
Think about how you will use your greenhouse daily.
Ease of Assembly
Some kits take an afternoon; others take a weekend. Check reviews to see if instructions are clear. Complex kits often require two people to build.
Year-Round Use
If you want to grow tomatoes in winter, you need a structure rated for the elements. Glass or thick polycarbonate with a strong frame is necessary for areas with heavy snow or strong winds.
Accessibility
For older gardeners or those with mobility issues, wide doors and low sills are important. Shelving placement should allow for easy reaching without excessive bending.
10 Frequently Asked Questions (FAQ) About Backyard Greenhouses
Q: How much space do I really need for a basic greenhouse?
A: A very small cold frame might only take up 4 square feet. For a walk-in model where you can stand, plan for at least 6 feet by 8 feet (48 square feet).
Q: Do I need a permit to put up a greenhouse?
A: This depends on your local town or city rules. Larger, permanent structures often need a building permit. Always check with your local planning office first.
Q: Which is better for heat retention: glass or polycarbonate?
A: Twin-wall polycarbonate panels trap air between the layers, offering much better insulation than standard single-pane glass.
Q: How do I stop my greenhouse from getting too hot in the summer?
A: You must use ventilation! Open roof vents and doors during the day. Shade cloth placed over the exterior also greatly reduces internal temperatures.
Q: Can I just put a greenhouse on my lawn?
A: While possible, it is not recommended. The structure needs a level, stable base. A gravel bed or treated wood frame prevents shifting and rotting underneath the structure.
Q: What is the cheapest type of greenhouse to buy?
A: Hoop houses covered with thick polyethylene plastic film are usually the least expensive option to purchase initially.
Q: How long do polycarbonate panels typically last?
A: Good quality, UV-treated polycarbonate panels can last 10 to 15 years before they start becoming brittle or yellowing noticeably.
Q: Are automatic vent openers worth the extra cost?
A: Yes, most experienced gardeners agree they are worth it. They use a wax cylinder that expands with heat, opening vents when you are away, preventing overheating.
Q: Can I use electricity inside my backyard greenhouse?
A: Yes, but you must use outdoor-rated or waterproof electrical boxes and outlets. It is safest to hire a licensed electrician for installation.
Q: What is “glazing”?
A: Glazing is the technical term for the transparent covering material—like glass or polycarbonate—that makes up the walls and roof of the greenhouse.
