Gardening can be a relaxing and gratifying hobby. Depending on what you choose to grow, you may even sell some of your gardens for extra income, or you might grow your own food.
Whatever the reason you garden, we think everyone should partake in it. Some settings aren’t conducive to gardening for certain parts of the year.
Maine is one of those places. With harsh winters overall and powerful storms in the south, gardening there year-round can seem impossible.
But we’ve found some of the best greenhouses for Maine. With the greenhouses on this list, you can vastly extend your growing season.

This greenhouse is a staple on any list of greenhouses for extreme environments. It may look unassuming at first, but trust us when we say it can stand up to just about any test.

Palram Hybrid Greenhouse
Efficiency might as well be the name of the Palram Hybrid Greenhouse. It has many features that make it poised to become any gardener’s best friend.
One thing we like, for example, is the exterior rain gutters. They’re especially useful in states with droughts because they permit gardeners to store rainwater to use at a later time. Maine may not be prone to droughts, but there’s no reason you couldn’t take advantage of the rainwater as a free resource, too.
Plus, the panels are made from twin-walled polycarbonate. Their increased thickness insulates the temperature in your greenhouse even better and ensures they’re more durable.
Pros
- Exterior rain gutters turn rain into a free source of water for you.
- Twin-walled panels diffuse the sunlight efficiently and boost stability in the temperature.
- The roof blocks up to 99.9% of UV rays, protecting your plants from being burnt.
- Its aluminum frame is resistant to rusting.
- A galvanized steel base holds the greenhouse firmly in place.
- The vent in the roof helps you control the temperature.
Cons
- Setting it up can take several hours.
Riga Greenhouse
The Riga Greenhouse appears in quite a few of our articles. This is one option that we know we could trust – and you could, too.
Its rounded shape makes it ideal for extreme environments. Snow can’t build up on the roof, and wind can flow over it without knocking it over. To be exact, it can handle winds up to 80 mph and hold up to 180 pounds of snow if any accumulates on it.
One thing we really love about it, though, is how its assembly is fuss-free. You won’t need any extra tools to put it together.
Pros
- Hassle-free assembly.
- The vents on top open and close automatically.

What to Consider When Buying a Greenhouse for Maine
Roof Weight Capacity
In Maine, the winters can be tough, with large snowfall. Unless your greenhouse has a rounded shape that naturally lets snow slide right off, you might want to think about how much snow the roof of your greenhouse can hold.
Usually, this information is included in the specifications or descriptions for each greenhouse. If you can’t find it there, we suggest checking out customer reviews. You can get an idea of which environments the greenhouse has thrived in through these comments.
Insulation
Because seasons in Maine can vary so much, a greenhouse that can preserve ideal temperatures is a must. Sufficient insulation will be one of the easiest ways to achieve this goal. It doesn’t require any effort on your part – it’s just incorporated in the very construction of the greenhouse.
Thick panels are one great way to insulate. Because they’re not as thin, cold air can’t leak in easily, and they’re also more resistant to cracking.
But some greenhouses take it a step further, sealing up the edges of their windows and doors. If you can find a greenhouse-like one, it’s a fantastic pick. However, if your greenhouse isn’t sealed up, you can always do this yourself by putting tape around any cracks and windows.
Air Ventilation and Circulation
Have you ever noticed how stuffy a house can get during the hot summer when all the windows are closed? The exact same thing happens in your greenhouse. This level of heat and stuffiness is no good for your garden.
That’s why your greenhouse needs to have ventilation. It’s extra important in a state like Maine, which can get humid during the summer. Although necessary for many plants to grow healthily, Humidity can also lead to rot, mold, and mildew.
Look for greenhouses with vents built-in. If you want something as easy as possible, you can refine your search further by looking specifically for greenhouses with automatic vents. Automatic vents will open on their own when it gets hot inside.
It’s even better if you can find a greenhouse with openable windows, too. That way, you can get more air flowing inside.
Light Diffusion
This is probably one of the most important aspects of any greenhouse. Diffusion refers to how well it disperses light to your plants.
Usually, this is affected by the material of the greenhouse’s panels. The two most common materials are polycarbonate and glass. Both types are excellent for diffusing sunlight, but the glass on its own can be fragile unless it’s tempered or safety glass.
Extra Features
A greenhouse can be as basic or sophisticated as you want it to be. There are plenty of additional and optional features to look out for if they interest you.
An example is built-in shelving. Not all greenhouses have it, but it can save you a little extra trouble when they do have it. It means you can instantly store containers and hanging baskets.
Most greenhouses have vents, but not all of them are automatic. As we mentioned previously, Automatic vents can save you time and trouble because you won’t need to run outside and open them up every time it gets hot out.
Some greenhouses even have integrated watering or misting systems. With a little bit of setting up, these systems will make it easy for you to water your plants.
Wrap Up
Hopefully, you’ve learned a lot about greenhouse gardening in this guide. Our goal is to show everyone that gardeners from all states can garden all year with the correct equipment, including a solid greenhouse.
If you asked us which one we’d pick as our favorite on this list, we’d go with the NW Green Panels Large Walk-In Greenhouse. We think the cabin aesthetic makes it perfect for Maine, and customers have reported it performing wonderfully in snowstorms.
Furthermore, its handmade appeal is irresistible. This is inarguably a greenhouse that has the potential to be any gardener’s pride and joy.
