Buying Guide: What to Look For in a Small Greenhouse for Beginners
When I first started looking for a small greenhouse, I was overwhelmed by the options. It’s easy to pick one just because it looks nice, but a few key considerations will make your first foray into greenhouse gardening much more successful. The right choice depends entirely on your space, budget, and what you want to grow. Let’s walk through the main things to think about before you get your first of the 10 best small greenhouses for beginners.
First, consider the frame material. You’ll mainly find steel, aluminum, and wood. Steel frames are strong and usually cost less, but they can rust if the coating isn’t good. Aluminum is lightweight and won’t rust, which is a big plus, but it can be a bit pricier. Wood frames, like cedar, look beautiful and provide excellent insulation, but they require more maintenance to protect them from the elements. For a beginner, a powder-coated steel frame is often a solid, affordable starting point.
Next, the cover is arguably the most important part. Polyethylene plastic (the kind you often see) is common and inexpensive. Look for UV-protected versions so it doesn’t break down in the sun after one season. Polycarbonate panels are a step up; they are twin-walled for better insulation, diffusing light to prevent plant scorching, and are much more durable than basic plastic. Glass offers the clearest light but is heavy, fragile, and expensive. For a beginner, a good quality UV-protected polyethylene or a twin-wall polycarbonate is a fantastic balance of cost and function.
Size and space are also critical. It’s tempting to get the biggest one you can afford, but be realistic about your yard or patio space. Measure twice! Think about not just the footprint but also the height – you need to be able to stand and work inside comfortably. Also, consider the base. Many small greenhouses need a solid, level base, like pavers or a wooden platform, to sit on for stability. A wobbly greenhouse is a recipe for disaster in a strong wind.
Ventilation is a feature many new gardeners forget. On a sunny day, the temperature inside a sealed greenhouse can soar and cook your plants. Look for models that include roof vents or large, zippered windows that you can open to allow hot air to escape. Some even have built-in roll-up side panels. Good airflow is also crucial for preventing mold and fungal diseases. If the model you like has limited ventilation, you might need to add a small fan.
Finally, think about assembly and anchoring. Check the product reviews to see what people say about putting it together. Some are straightforward, while others can be a real puzzle. Also, a lightweight greenhouse can become a kite in a storm if it’s not properly anchored. Many come with ground stakes, but you might need to purchase additional anchor kits for peace of mind. Taking the time to secure it properly will protect your investment and your plants.
FAQ
Where is the best place to put a small greenhouse?
The best spot receives maximum sunlight, ideally facing south. You want at least six hours of direct sun per day. Make sure it’s not in a low-lying area where water pools, and try to place it in a location that’s sheltered from strong, prevailing winds. Also, consider proximity to a water source; you don’t want to haul a hose across your entire yard.
What can I grow in a small greenhouse as a beginner?
Start with plants that are rewarding and relatively easy. Leafy greens like lettuce and spinach are great, as are herbs like basil and cilantro. Radishes are very fast-growing. You can also use it to get a head start on summer vegetables like tomatoes and peppers from seed. It’s also perfect for protecting frost-sensitive plants in the spring and fall.
Do I need to heat my small greenhouse in the winter?
It depends on your climate and what you’re growing. An unheated greenhouse, often called a “cold frame,” will protect plants from frost but won’t keep them warm during a deep freeze. If you want to grow through a cold winter, you’ll likely need a supplemental heat source, like a horticultural heating mat for seedlings or a small, safe electric greenhouse heater. Good insulation with bubble wrap can also help.
How do I control the temperature and humidity inside?
Temperature is managed through ventilation. Open vents and doors on warm, sunny days to let heat out. In contrast, closing everything up at night helps retain warmth. For humidity, watering your plants will naturally raise the humidity level. If it gets too humid, which can encourage disease, increase ventilation. A simple thermometer and hygrometer inside will help you keep track of both.
Are these small greenhouses durable against wind and snow?
Durability varies greatly by model. Inexpensive, lightweight kits with thin covers are vulnerable to strong winds and can collapse under snow load. Sturdier frames with polycarbonate panels are much more resilient. No matter what you buy, proper assembly and securing it firmly to the ground with anchors is the most important step for ensuring it can handle bad weather. When looking at the 10 best small greenhouses for beginners, pay close attention to reviews that mention stability in storms.
Can I assemble a small greenhouse by myself?
Many of the smaller, hobby-style greenhouses are designed for one-person assembly, but I would not recommend it. The process is almost always easier and safer with a helper. The frames can be awkward to hold in place, and the cover materials can be tricky to align and secure without an extra set of hands. Always read the instructions thoroughly before you start and set aside a good chunk of time for the project.
