With microgreens, it’s generally a good idea to have some air circulation in your greenhouse. Aside from bringing the temperature down, it can wick away excess moisture and humidity, which can stop mildew from growing.

This greenhouse has a fantastic setup for airflow. It has several windows on the sides, and since they’re across from each other, opening them can form a soothing cross breeze.

There are even screens on the inside of each window, so you can open them without having to worry about insects getting inside.


  • Windows across from each other on the sides are excellent for air circulation.
  • There are screens on the inside of the windows to keep pests out.
  • The cover is double-threaded for longevity and weather resistance.
  • Its large size accommodates a bigger number of plants.


  • Because it’s a tent structure erected with stakes, you’ll need to secure it to protect it from harsh winds.

Riga Greenhouse

Riga Greenhouse


The Riga Greenhouse is one we’ve written about quite a lot before. In essence, that’s simply because it’s just an all-around quality choice.

Although it will largely depend on what type of microgreens you’re trying to grow, many types need a little humidity and moisture. The problem with this is that warm, moist environments often lead to mold, mildew, and pests.

To combat that, the Riga Greenhouse has automatic vents built into its roof. This will help generate airflow that prevents the growth of mold and mildew. It also doubles as the most convenient way to lower the temperature when it gets too warm inside.

Better yet, the materials used to make it are resistant to rotting, mildew, and UV rays. That means you won’t need to be concerned about replacing it anytime soon.


  • Made from materials resistant to mildew and rotting.
  • Vents on the top will open on their own when it gets hot.
  • Durable and capable of resisting winds up to 80 mph.
  • Easy assembly that doesn’t need additional tools.
  • Large size accommodates tons of plants.
  • There are shelves on the side to hold your containers of microgreens.


  • No issues reported at this point in time.

Mt. Hood Greenhouse

Mt. Hood Greenhouse


This greenhouse is another frequent addition to our lists. That’s because we’re confident in its quality.

Depending on where you’re located, you might need the durability that this greenhouse brings to any garden. Its redwood frame can stand winds up to 100 mph, which is phenomenal. Its panels are made from polycarbonate that’s just about impossible to destroy.

Panels covering every side and the roof are designed to heat the interior as efficiently as possible. On the roof, the slanted panels can catch more sunlight for longer, even on winter days. In fact, it’s estimated that you’ll save up to 40% on heating costs with a greenhouse this well-designed.


  • Extremely efficient heating.
  • The organic base resists pests and mildew.
  • Panels let in plenty of sunlight and are virtually indestructible.
  • Its frame is made from all-natural redwood.


  • Some feel that the setup instructions aren’t very clear.

Palram Mythos Greenhouse

Mythos 73" W x 97" D Greenhouse


What we love about the Palram Mythos Greenhouse is that, at 6 feet wide and 8 feet deep, it’s more than spacious enough for your microgreens. However, it’s not so large as to take up your entire yard.

Once you get it set up, it’s a greenhouse that you can expect to last. Its base is galvanized steel, and you can screw it into a cement or wood foundation to ensure it stays in place permanently.

We also love the vent built into the top of the roof. This could be the difference between your microgreens dying or thriving when it starts to get hot inside.


  • Has a roof vent for air circulation and temperature control.
  • The steel base is stable and long-lasting.
  • You can add an optional lock to the front door if you would prefer the extra security.


  • Some owners felt it was tough to assemble.

What to Consider when Buying a Greenhouse for Microgreens


Microgreens can get pretty delicate. Because of this, they need to be protected from the cold as best as possible.

One way to do this is to have a greenhouse that’s well-insulated. This will be largely influenced by what the surface is made from.

For most greenhouse kits, you’ll see polycarbonate panels. Polycarbonate is tough, so it’s perfect for standing up to weather conditions. It’s even better if it’s twin-walled, because these thicker panels will insulate better against temperature changes.

If your greenhouse is not insulated very well, you can do it yourself with a little work. Bubble wrap and tape are things you can use to seal up cracks around doors and windows.

Ventilation and Airflow

Because many microgreens need a lot of moisture, excessive humidity can become a problem quickly. You’ll want to protect your microgreens from mold, mildew, fungus, and pests that thrive in humid conditions.

Airflow and ventilation will be your best tools against these threats. When you look for a greenhouse, make sure you determine what kind of vent setup it has.

There are quite a few greenhouses now with automatic vents, which are phenomenal. These vents don’t take any effort on your part – they will open on their own whenever it gets too hot inside.

But air circulation is also important. Additional windows to form a cross breeze are perfect for this. Another option is to add a fan like this one to your greenhouse.

Sunlight Absorption

A greenhouse’s main function is to take in sunlight. Some microgreens need a lot of light and warmth, so the more efficiently your greenhouse can do this, the better.

There are a variety of factors that affect how much sunlight your greenhouse can absorb. The material it’s made from will be the biggest concern, though.

Polycarbonate panels are great for letting in sunlight while also protecting your plants from UV rays. Tempered glass is another common material, but can sometimes be a little fragile.

Wrap Up

Growing your own microgreens can be an affordable and fun way to add a healthy touch of green to any dish. If you’re planning to do this all year, though, you’ll need a greenhouse that’s up to the challenge.

Part of choosing a greenhouse will depend on exactly what kind of microgreen you’re choosing to grow. If we had to choose one overall greenhouse, though, we’d recommend the Riga Greenhouse. Its spacious interior will give you all the room you need to grow a garden regardless of your environment.

The shelves are endlessly useful, too. Right from the start, you’ll have the shelving you need to hold your containers without having to buy it separately.
