Choosing Your Backyard Greenhouse: A Simple Buying Guide
A backyard greenhouse lets you grow plants all year long. It protects them from bad weather. It also helps you start seeds early. Finding the right one means thinking about a few important things. This guide will help you pick the best greenhouse for your garden.
Key Features to Look For
When shopping, check these features first. They make a big difference in how well your greenhouse works.
Size and Space
- Footprint: Measure your yard space. Greenhouses come in small cold frames or large walk-in models.
- Height: Taller greenhouses let you stand up inside. This makes working easier.
- Shelving Space: Think about how many plants you have. You need room for shelves or benches.
Ventilation
Good airflow keeps plants healthy. Hot air rises. You need vents to let that hot air out.
- Roof Vents: These are very important for letting heat escape.
- Side Vents or Louvers: These help bring cooler air in from the sides.
Ease of Assembly
Some kits assemble quickly. Others take much longer. Read reviews to see how hard the setup is. Clear instructions help a lot.
Important Materials Matter
The frame and the covering materials affect how long your greenhouse lasts and how well it insulates.
Frame Materials
- Aluminum: This is very popular. It resists rust and lasts a long time. It is lightweight, too.
- Steel: Steel frames are strong. They handle heavy snow loads better. Sometimes, steel needs a protective coating to prevent rust.
- Wood: Wood looks nice. You must treat it regularly to stop rot.
Glazing (Covering) Materials
This is what lets the light in.
- Polycarbonate Panels: These are strong plastic panels. They diffuse light well. This means light spreads out evenly, which plants love. They handle impacts well.
- Glass: Glass provides the clearest view. It lets in the most light. However, it breaks easily. It can also get too hot on sunny days.
- Polyethylene Film (Plastic Sheeting): This is the cheapest option. It works for temporary or small structures. It needs replacing every few years.
Factors That Improve or Reduce Quality
Quality is about durability and performance. Some features boost quality; others lower it.
Improving Quality
- Strong Foundations: A greenhouse should sit on a level, sturdy base. This keeps it stable.
- UV Protection: Make sure the plastic or polycarbonate covering has UV inhibitors. This stops the plastic from turning yellow and brittle in the sun.
- Automatic Vent Openers: These use wax that expands when hot. They open and close vents without electricity. This maintains a perfect temperature automatically.
Reducing Quality
- Thin Frames: Very thin aluminum frames bend easily in strong winds.
- Poor Sealing: If the panels do not fit tightly, cold air leaks in during winter. This wastes heat.
User Experience and Use Cases
Think about why you want the greenhouse. This shapes your needs.
Seed Starting and Season Extension
If you only want to start tomatoes early, a small cold frame or a simple hoop house works well. These are easy to set up.
Year-Round Growing
For growing tropical plants or overwintering sensitive herbs, you need a sturdy, well-insulated structure. You will need a heater for cold climates. A glass or double-walled polycarbonate structure performs best here.
Hobby vs. Serious Gardening
Hobby gardeners might accept less durable materials. Serious gardeners should invest in aluminum frames and thick polycarbonate. They prioritize longevity and better temperature control.
10 Frequently Asked Questions (FAQ) About Backyard Greenhouses
Q: Do I need a permit to build a backyard greenhouse?
A: Many local towns require permits for structures over a certain size. Always check with your local building department first.
Q: How much does a decent backyard greenhouse cost?
A: Prices range widely. Small, basic kits start around $150. Large, high-quality walk-in models can cost $1,000 or much more.
Q: Which material is best for keeping heat in during winter?
A: Double-walled polycarbonate panels trap air between the layers. This traps heat much better than single-layer glass or plastic film.
Q: Can I put a greenhouse on grass?
A: You can temporarily place a small one on grass. For long-term use, you should build a level foundation, like gravel or concrete. This stops pests and keeps the frame square.
Q: What is “glazing”?
A: Glazing refers to the transparent material covering the greenhouse frame. This is usually glass or polycarbonate panels.
Q: How do I stop my greenhouse from getting too hot?
A: You must use ventilation. Open roof vents and side vents when the sun shines brightly. Shade cloth also reduces intense direct sunlight.
Q: Are aluminum frames strong enough for snowy areas?
A: Standard aluminum frames are okay for light snow. For heavy snow, choose models designed with stronger bracing or a steeper roof pitch.
Q: Do I need electricity in my greenhouse?
A: Electricity is not always needed. But if you plan to use a heater, fans, or automatic watering systems, you will need an outdoor power source.
Q: What is the easiest type of greenhouse to assemble?
A: Small, plastic hoop houses or cold frames usually have the easiest assembly. Large, rigid frame kits take the longest time.
Q: How long does a polycarbonate covering last?
A: High-quality, UV-protected polycarbonate panels often last 10 to 15 years before they start degrading from the sun.
