#2: Sellerwe Black Kit (Great Budget Polycarbonate Greenhouse)

This was unexpected, I’ll admit. It comes for a brand (Sellerwe) that I had never heard of and has very little online presence.

This was a really nice polycarbonate greenhouse that not only made a cosy environment for my plants but also didn’t cost an absolute fortune to own. It was a little trickier to assemble than others but nothing me and a friend couldn’t handle. All around this was a good choice and I’d happily recommend it.

Which 10×12 Greenhouse Should You Avoid?

Now is the tricky part of this article, because I never like telling people to avoid certain products. The truth is that I really didn’t like the Yitahome 10×12 ft polycarbonate greenhouse and the reviews on Amazon kind of reflect this.

---

---

I found that it was a nightmare to assemble because the instructions weren’t clear, the pieces didn’t fit very well and there were even things missing. Overall it felt like it was sloppily put together so I figured that I’d include this here so that you can avoid going through what I did.

Or if it’s for sale then give it a try if you like. It comes at a nice price and maybe my experience was isolated and you love it.

Factors to Consider Before Purchasing a 10×12 Greenhouse Kit

Before purchasing a greenhouse kit, you should consider the available space in your backyard and ensure that the size fits your needs. It’s important to carefully evaluate the materials used in the kit for durability and resistance to high winds if you plan on using it year-round.

Size and Space Availability

The size should also align with your outdoor area, ensuring that the chosen spot can accommodate the dimensions of the kit without overcrowding other elements in your backyard or garden.

Material and Durability

When choosing a greenhouse kit, consider the material and its durability. Opt for durable materials like aluminum or galvanized steel frames that can withstand high winds and heavy snow loads.

Additionally, look for greenhouse kits with UV-resistant coatings to prevent yellowing and brittleness over time. Properly maintained metal components can resist rust and corrosion, prolonging the lifespan of your greenhouse kit.

Added Features (such as gutters, vents, and double doors)

When it comes to the structural components and additional features of a greenhouse kit, several elements can enhance functionality and durability. Here are the added features you should consider:

1. Integrated Gutters: These allow for efficient collection and management of rainwater, facilitating irrigation systems and reducing water wastage.
2. Adjustable Vents: Equipped with automatic openers or manual controls, vents maximize air circulation, humidity control, and temperature regulation within the greenhouse.
3. Double Doors: Wide access points provide ample room for maneuvering equipment and transporting larger plants in and out of the greenhouse while promoting a smooth flow of traffic within the space.

These added features not only contribute to the overall functionality but also augment the longevity and effectiveness of your greenhouse kit.

Make Sure That You Grab Some Greenhouse Accessories:

I know that I might be preaching to the choir here, but every greenhouse should be equipped with a range of accessories to optimize plant growth, ensure durability, and enhance usability. Here’s a list of essential accessories:

The Govee Smart Thermometer is incredible (and cheap)

Thermometer and Hygrometer: To monitor the temperature and humidity levels inside the greenhouse, ensuring they are optimal for plant growth.

Ventilation System: Proper ventilation is crucial for regulating temperature, removing excess humidity, and ensuring a steady supply of fresh air. This can include fans, roof vents, side vents, and automatic vent openers.

Heating System: For colder climates or seasons, a heating system is essential to maintain a consistent temperature. Options include electric heaters, gas heaters, or solar-powered heaters.

Cooling System: In warmer climates or during hot spells, shading cloths, evaporative coolers, or fans can help to keep the greenhouse from overheating.

Irrigation System: An automated watering system, such as drip irrigation or soaker hoses, can save time and ensure plants receive the right amount of water.

Vivosun has some great hydroponic systems that you should look into

Grow Lights: For areas with limited natural light or during the shorter days of winter, grow lights can provide the necessary spectrum of light for plant growth.

Shelving and Potting Benches: Maximizing space with shelving for plants and having a dedicated area for potting and repotting plants are practical for organization and efficient use of space.

Each greenhouse and its environment are unique, so the specific needs may vary. However, equipping a greenhouse with these accessories can greatly enhance its functionality and the overall gardening experience.
