It works well both indoors and outdoors, and it’s a nice size that fits perfectly in most gardens. The quality is high, and it does its job really well.

Overall Thoughts

I’m a firm believer in the idea that anything made by Quictent is going to be a good purchase. The reason is because they know exactly what they are doing. Things aren’t different with this raised garden bed greenhouse – they created a plastic greenhouse that looks great in the garden, works well and is also sturdy. As always the customer support is also a big plus because if there are any problems they are quick to solve them.

The downsides? The assembly process is a bit more challenging because the instructions aren’t always clear and this is an entry level plastic greenhouse that doesn’t give you a massive amount of space for your plants. So just be prepared that you’re going to need to intentionally choose which plants go in there.

PROS	CONS

What Are The Different Types Of Plastic Used With Greenhouses?

These are the most common types of plastic that you’ll see on greenhouses.

Polyethylene (PE): This is the most common plastic used for greenhouse covers. It’s affordable and flexible, making it easy to handle. There are two types: low-density (LDPE) and high-density (HDPE). LDPE is more flexible and cheaper, while HDPE is tougher and more durable.

Polycarbonate (PC): This type is more expensive but very durable and long-lasting. Polycarbonate panels are clear and let in plenty of light, which is great for plant growth. They also provide good insulation and protect plants from UV rays.

Polyvinyl Chloride (PVC): PVC is another option for greenhouse covers. It’s durable and can withstand weather changes. However, it’s less common than polyethylene and polycarbonate because it can degrade faster under direct sunlight unless treated with UV protectants.

Ethylene Vinyl Acetate (EVA): This plastic is similar to polyethylene but has better light transmission and heat retention. It’s more flexible and can last longer, but it’s also a bit more expensive.

Which Should You Choose?

Here’s a quick summary of each of the options.

Polyethylene (PE):

• Most common and affordable.
• Flexible and easy to handle.
• Two types:
  • Low-Density (LDPE): More flexible and cheaper.
  • High-Density (HDPE): Tougher and more durable.

Polycarbonate (PC):

• More expensive but very durable and long-lasting.
• Clear panels let in plenty of light.
• Provides good insulation and UV protection.
• Ideal for long-term use and optimal growing conditions.

Polyvinyl Chloride (PVC):

• Durable and can withstand weather changes.
• Less common than PE and PC.
• Can degrade faster under direct sunlight unless UV-protected.
• Good for resilience but watch for longevity in sunny climates.

Ethylene Vinyl Acetate (EVA):

• Similar to polyethylene but with better light transmission and heat retention.
• More flexible and can last longer.
• Slightly more expensive.
• Great for superior light and heat performance.

Conclusion

Choosing the right plastic greenhouse can make a big difference in your gardening success. Whether you’re looking for a durable option like the Palram Hybrid, a versatile and affordable greenhouse like the Home-Complete Walk-In, or a smart indoor option like the Barrina Smart Indoor, there’s something for everyone.

Each of these greenhouses has its own strengths and is suited for different needs and budgets. The key is to consider what you need most—whether it’s durability, ease of assembly, or specific features like built-in grow lights. By understanding the different types of plastic and what each greenhouse offers, you can make an informed decision that will help your plants thrive.

Happy gardening, and here’s to a successful growing season with your new plastic greenhouse!

FAQs

Are plastic greenhouses any good?

Yes, plastic greenhouses are a great option for many gardeners. They are typically more affordable than glass greenhouses and can be very effective at creating a controlled environment for your plants. They’re also lighter and easier to set up, making them ideal for both beginners and experienced gardeners.

What are the disadvantages of plastic greenhouses?

While plastic greenhouses have many benefits, there are a few disadvantages to consider. They can be less durable than glass and might degrade over time, especially if they’re not UV-protected. They can also be less aesthetically pleasing and may not provide the same level of insulation as glass greenhouses.

Do plastic greenhouses stay warm?

Yes, plastic greenhouses can stay warm by trapping heat from the sun. They help create a microclimate that keeps your plants warm even when it’s cooler outside. However, they might not retain heat as well as glass greenhouses, so you might need to use additional heating methods in very cold weather.

How long do plastic greenhouses last?

The lifespan of a plastic greenhouse can vary depending on the quality of the materials and how well it’s maintained. Generally, a good quality plastic greenhouse can last anywhere from 5 to 10 years. UV-protected plastics tend to last longer as they are more resistant to sunlight damage.

Is a plastic greenhouse better than a glass greenhouse?

Whether a plastic greenhouse is better than a glass greenhouse depends on your needs. Plastic greenhouses are more affordable, lightweight, and easier to set up. Glass greenhouses, on the other hand, are more durable, provide better insulation, and have a classic look. If you’re on a budget or need something easy to move and set up, a plastic greenhouse is a great choice. If you’re looking for long-term durability and better insulation, a glass greenhouse might be the better option.
