16 Best Glass Greenhouses in 2022

Glass greenhouses are in fashion this season!

If you are an avid gardener or would like to get your green fingers into the hobby soon, a glass greenhouse is a great way to create an entire ecosystem while you have complete control over the environment.

Glass greenhouses are eco-friendly. A glass greenhouse lets in more light distribute heat in more even ways and makes for happier plants on the inside. Greenhouses are not always eco-friendly when they are made from other materials, like plastic or polycarbonate.

It can be difficult to find the right glass greenhouse for your needs: just one Google search gives you a thousand different options, from large ones to small ones, fancy ones to simple ones.

How can you pick the best cheap glass greenhouse?

We’re here to help!

Here’s what you should know about why glass greenhouses are the environmentally responsible, eco-friendly choice – and a buying guide for the 16 best glass greenhouses you can find online.

About Glass Greenhouses

A Glass Greenhouse

Greenhouses are not all “green” when we’re talking about their levels of eco-friendliness.

When greenhouses are made from plastic or polycarbonate materials, they can attract more heat than is healthy for your plants. Sunlight is important for plants, but creating a heated environment for your plant collection isn’t always the best option.

Non-environmentally-friendly greenhouses lead to resource wastage in the long term. When elements like heat and sun are wasted on your plants, it has a direct impact on the environment around us – and of course, the environment inside your greenhouse.

More gardeners and gardening enthusiasts are choosing glass greenhouses this year. Eco-friendly glass greenhouses equal fair heat distribution and total environmental control.

It’s what every gardener really wants!

What is a glass greenhouse?

Glass greenhouses have been made from authentic glass material, usually together with aluminum or steel frames surrounding them. The eco-friendly difference lies in the use of glass instead of polycarbonate material or plastic.

A lot of gardeners all over the world are making a switch to glass greenhouses. Others are beginning their journey with a glass greenhouse.

Plastic and polycarbonate materials have a large environmental impact. They are expensive to produce, never degrade, and create a huge carbon footprint just to make.

Glass, overall, is better for the environment and your garden.

Why are glass greenhouses great?

Glass greenhouses are great thanks to their use of glass, which ensures that space and heat are used effectively. Sunlight and airflow are important components of a healthy greenhouse, but artificial materials like plastic can interfere with your ecosystem.

Glass greenhouses are durable, affordable, and better for the environment inside (and outside) of your greenhouse.

The carbon footprint of producing a glass greenhouse is also comparatively much less weighed up against regular, non-eco-friendly greenhouses on the market.

As gardeners, the environment is important – and a switch to a glass greenhouse can help you to do more to protect nature.

FAQ: Things to Consider

Before you make the final click to buy your next glass greenhouse, there are a handful of important things you should consider first. What makes a great greenhouse compared to an average model? What should you know if you have never attempted to install a greenhouse before?

Here’s a quick FAQ that can help to bring novice gardeners up to speed.

1. The Foundation

Most glass greenhouses will require a foundation to install it on. The foundation is a simple brick platform that measures, more or less, the same as the floor space of your intended greenhouse.

Foundations are for added strength. Greenhouses can be heavy, and a foundation stops it from sinking or moving into the ground. Make sure your foundation is just as good as the model of greenhouse that’s going on top of it.

If you have never put a greenhouse anywhere before, don’t forget about the foundation!

2. The Height

Greenhouses measure at different heights. Factor in the height of the greenhouse relative to the height of anything that might be close to your greenhouse’s space.

Nobody wants to put a greenhouse in the way of a power line or tree branch just because they “didn’t think it would be that high”, right? Plan out the position of your greenhouse before proceeding.

Height matters.

3. The Accessories

Accessories are another important factor when buying your greenhouse. What the heck is greenhouse accessories? They can include sprinkler or mister systems, gutters, and additional shelves – all of which you might need to install yourself or buy extra once you have the greenhouse of your choice.

When installing your accessories, remember that not all greenhouses are the same. Fittings, clips, and screws will be different from one model to the next.

4. Need Help?

The installation of a glass greenhouse is described as a DIY process, but it’s fair to admit that not everyone is great at handiwork. If you have trouble installing a greenhouse or don’t feel confident enough in your own abilities to do it, professional installation services exist.

Sometimes, parking a greenhouse in your garden is just a two-person job that requires some heavy lifting and a bit of holding up.

While DIY, it’s not a task anyone would recommend completing alone!
