Your Backyard Greenhouse Buying Guide: Grow Your Dreams!
A backyard greenhouse is a fantastic way to extend your growing season, protect delicate plants, and even grow things you couldn’t before. Choosing the right one can feel overwhelming, but this guide breaks down what you need to know before you buy.
1. Key Features to Look For
When you shop, focus on these important features. They make a big difference in how well your greenhouse works.
Ventilation is Vital
- Roof Vents: These are windows on the roof that open up. Hot air rises, so opening these lets the super-hot air escape easily. Look for models that have automatic openers that use wax cylinders—they open when it gets hot without you needing to rush home!
- Side Vents or Louvers: These allow air to flow in low down. Good airflow keeps plants healthy and prevents diseases.
Door Design Matters
Make sure the door is wide enough for you to move comfortably while carrying trays or a wheelbarrow. Sliding doors save space compared to hinged doors that swing out.
Foundation and Anchoring
Your greenhouse needs a solid base. Check if it comes with a base frame or if you need to pour a concrete slab. Strong anchoring kits (stakes or bolts) are essential so wind doesn’t blow your investment away.
2. Important Materials: What is it Made Of?
The frame and the covering material determine how long your greenhouse lasts and how well it insulates.
Frame Materials
- Aluminum: This is the most common choice. It is lightweight, strong, and will never rust. It is a great long-term option.
- Steel: Steel frames are very strong, especially for larger structures. However, cheaper steel might rust over time unless it is heavily galvanized (coated to prevent rust).
Glazing (Covering) Materials
This is the clear part that lets the sunlight in.
- Polycarbonate Panels: These are sheets of tough plastic, often twin-wall (two layers with air in between). They offer great insulation and are very impact-resistant—a baseball won’t shatter them. This is usually the best choice for most homeowners.
- Glass: Glass lets in the most natural light. It looks beautiful, but it breaks easily and does not insulate as well as polycarbonate unless you use expensive double-paned glass.
- Polyethylene Film (Plastic Sheeting): This is common on cheaper, temporary hoop houses. It is inexpensive but needs replacement every few years.
3. Factors That Improve or Reduce Quality
Quality isn’t just about the price tag. Look closely at the construction details.
Improving Quality
- Thicker Frame Profiles: Thicker aluminum or steel frames handle snow loads and high winds much better.
- UV Protection: Ensure the polycarbonate panels are treated to resist UV rays. Untreated plastic turns yellow and brittle quickly.
- Weather Stripping: Good seals around doors and vents keep heat in during winter and stop pests from getting inside.
Reducing Quality (Watch Outs)
Avoid flimsy construction. If the assembly instructions look too simple, the frame might be made of thin metal that bends easily. Plastic connectors or clips often break in the first few years.
4. User Experience and Use Cases
Think about how you plan to use your new space. This affects the size and height you need.
Greenhouse Use Cases
- Seed Starting (Small Scale): If you only start seeds early in the spring, a small, inexpensive cold frame or a compact shelving unit greenhouse might be enough.
- Year-Round Gardening (Medium Scale): If you want to keep tomatoes growing into the fall or grow tropical plants through winter, you need a structure that can hold a small heater and has good insulation (like twin-wall polycarbonate).
- Potting Shed/Workspace (Large Scale): If you plan to stand up, work on tables, and store tools inside, you must choose a structure with high, walk-in clearance (usually 6.5 feet at the eaves or higher).
Assembly time is also part of the experience. Some kits require two people a full weekend to assemble, while others can be put up in an afternoon. Check online reviews specifically about the difficulty of the build.
10 Frequently Asked Questions (FAQ) About Backyard Greenhouses
Q: How big of a greenhouse do I really need?
A: Get bigger than you think you need! Plants take up space quickly once they start growing. A 6×8 foot model is a good starting point for hobbyists.
Q: Do I need planning permission for a backyard greenhouse?
A: This depends on your local town or city rules. Small, temporary structures often don’t need permission, but permanent, large structures usually do. Always check first!
Q: What is the biggest threat to my greenhouse in the winter?
A: Heavy snow loading on the roof can cause weak frames to collapse. Ensure your frame material is rated for local snow conditions.
Q: Can I use my regular garden hose inside the greenhouse?
A: Yes, but consider installing a simple drip irrigation system. It saves water and ensures plants get consistent moisture, which is better for them.
Q: What is the difference between a cold frame and a greenhouse?
A: A cold frame is low to the ground, usually unheated, and used only to harden off seedlings or protect very hardy plants. A greenhouse is tall enough to walk into and is designed for longer-term growing.
Q: Is polycarbonate better than glass for beginners?
A: Yes. Polycarbonate is safer (it doesn’t shatter) and provides much better insulation, which saves you money on heating bills.
Q: How do I stop my greenhouse from getting too hot in the summer?
A: Use the roof vents to let hot air out. You can also use shade cloth draped over the outside during the hottest part of the day.
Q: Should I put my greenhouse on dirt or a solid foundation?
A: A solid foundation (like gravel over weed barrier or concrete) is best for permanent structures. It keeps pests out and provides a stable, level base for assembly.
Q: How do I heat a greenhouse affordably?
A: The best method is insulation first! Use bubble wrap or commercial insulation on the inside walls when it gets very cold. Then, use a small, electric space heater specifically designed for damp environments.
Q: What is the minimum amount of sunlight a greenhouse needs?
A: Most vegetables and flowering plants require at least six hours of direct sunlight daily. Place your greenhouse where it gets morning and early afternoon sun.
