Outsunny polycarbonate greenhouses

Polycarbonate greenhouses are the most popular Outsunny greenhouses. The polycarbonate panels are durable, weather-resistant, and budget friendly. These greenhouses come in many different sizes and you are sure to find a good fit for your needs.

Outsunny polycarbonate greenhouses will offer you the opportunity to grow all year long. They offer great protection against wind and rain and capture the sunlight and humidity to help your plants and seedlings grow. You can add ventilation during summer and heating during winter to create the perfect growing circumstances all year long.

Let’s take a look at the best polycarbonate Outsunny greenhouses!

1. Outsunny Polycarbonate Portable Walk-in Garden Greenhouse

This greenhouse comes in 3 different sizes, 6’L x 4’W x 7’H, 6’L x 6’W x 7’H, 6’L x 8’W x 7’H. The 6’x4’ greenhouse is perfect for helping seedlings to germinate or grow spices and herbs. When you want to grow larger plants, it will soon feel too small. The most popular Outsunny greenhouse size is 6’x8’. Big enough to offer you enough room to roam around and to do some serious growing.

This greenhouse is a very popular model, for many reasons:

  • The assembly is very doable. You can do it by yourself, but we would recommend recruiting another person to help you. It will take you between 4 and 6 hours to put everything together. Seal the panels with silicone when you finish, this will add extra insulation and make your greenhouse more durable.
  • Budget friendly: good quality greenhouse for an affordable price. Need we say more?
  • Great customer support: when something would go wrong with the assembly or a piece is missing, you can contact customer support. They are very helpful and quick!
  • The UV resistant paneling and steel frames are strong and durable
  • The sliding door is convenient and allows you to easily access the greenhouse

We would definitely recommend this greenhouse. The only thing that you have to take into account is that this greenhouse might not survive extreme winds and harsh storms. It should however hold up fine in ‘normal’ weather circumstances and light storms. If you want to add extra stability, make sure you anchor your greenhouse into the ground.

2. Outsunny Stable Outdoor Walk-in Garden Greenhouse with Roof Vent and Rain Gutter 8’x6.25′

In our opinion, this is the best Outsunny greenhouse, especially in the polycarbonate category! It’s bigger and slightly more equipped than the one above. It has a really nice size to be able to grow almost anything you like and will give you the freedom to easily move around in your greenhouse. This model is a little more weather resistant than the one above. It should be able to withstand stronger winds, especially when you anchor it in the ground. Sealing the panels with silicon will also help the durability and strength of this greenhouse.

The biggest advantages of this greenhouse:

  • Budget friendly: it’s a really good size and quality for a very affordable budget. It’s a little more expensive than the smaller model, but cheaper compared to most competitors.
  • It comes with built-in rain gutters to collect rainwater. If you install a hose near your greenhouse, you can easily water your plants without dragging a watering can back and forth
  • Strong and UV resistant panels and aluminum frames
  • Assembly is perfectly doable. Make sure you read the manual in advance and lay out all the parts. Like the one above, we would definitely recommend to do it with 2 people. This greenhouse is too big and heavy to assemble by yourself.
  • If however something would go wrong with the assembly or delivery, customer service is extremely helpful and will send you missing or broken parts immediately
  • Built-in roof vent: The roof vent allows you to let fresh air in during summer to prevent your plants from overheating.

Because some of the reviews are critical about the ability to withstand heavy winds, it might be a good idea to windproof your Outsunny greenhouse in advance. Take a look at this article to learn more!

Outsunny plastic cover greenhouses

The plastic cover greenhouses are perfect for indoor growing or to protect your plants from mild weather conditions. If you want to raise the temperature a couple of degrees and keep insects away, this budget friendly option is perfect for you. It’s also a great way to help seedlings germinate, when your plants start growing you can move them out of the greenhouse.

A plastic cover greenhouse needs to be taken inside during winter and won’t withstand harsh weather conditions such as heavy winds and rain.

Whether you’re moving it inside during winter or taking it with you to a new home, these greenhouses offer flexibility.

Outsunny offers many different sizes and ranges in the plastic cover range. Let’s take a look at the most popular models!

This greenhouse will capture the heat and moisture and create great circumstances for your plants to grow. It also comes with shelves on both sides, which is convenient to start setting up quickly. All in all this greenhouse offers good quality for a very reasonable price. In our opinion, the best Outsunny greenhouse in the plastic cover category!

4. Outsunny Portable Mini Greenhouse with Large Zipper Doors, 9′ L x 3′ W x 3′ H

Like most Outsunny products, this mini greenhouse stands out because of the price/quality ratio. When you’re looking for a small greenhouse to protect your plants, this is a great pick for you. It’s UV protected and will still allow the light to reach your plants. Like most plastic cover greenhouses, this is made to protect plants from mild weather conditions. It could withstand some wind, because it’s not too high, but we would advise adding protection during a summer storm. Luckily for you, you can easily move this greenhouse inside during winter!

The assembly is very easy and will be finished in less than half an hour. The zippers and plastic are of good quality and easy to use. You can bury the cover in the soil for added stability and roll up the doors for ventilation.
