Gardeners, Listen Up! We’ve Rounded Up the Top Greenhouses for Your Plants

Are you interested in taking up a new hobby? Have you thought of gardening? If you groaned at the thought of all the hard work, don’t worry! You can find all the great gardening tools that will make your life easier. From a garden hose to a lawnmower, there is a tool for any small or large garden. Don’t want to deal with grass and weeds? Then go for some pots and flower beds that are not as high-maintenance as full garden tending. 

But, what happens when winter weather hits and your plants start slowly dying? Wouldn’t you love to find a way to keep them alive and well protected from severe weather conditions and high winds? Plus, it’s more likely that you’ll get up and take care of your flowers if you’re not soaked from the rain. Cue greenhouses to do the trick! 

With the best greenhouses, you can keep your pots, trays and flower beds looking as brand as new. Small or large gardens, you can grow your own vegetables even in the basement. Fresh and organic produce from the comfort of your home! We’ve taken the time to review the best options available on the market so that you can make an informed decision. Our buying guide has all the answers to your questions. No need to look anywhere else!

What is a greenhouse?

A greenhouse is a worthy investment for any size garden or even patio use. It is a secure framed structure with walls and a roof to protect pots and plants from bad weather. Greenhouses are the perfect controlled environment for the best quality plants. The outside conditions don’t affect your flowers because it’s a confined space. There are different types and sizes that come in many material types. From mini hothouses, known as cold frames, to large commercial greenhouses. No matter the garden size and experience level, you can find a choice to match your gardening needs.

For young plants that are too tender to make it through harsh weather, a greenhouse is a safe and protected environment. Greenhouses absorb the light and feed it to the plants so that they can thrive. That’s also very important for vegetables that too often frost when the temperatures are low. The light that comes into the greenhouse gives heat and warmth to the vegetables, allowing them to ripen. 

Why should you buy a greenhouse?

Are greenhouses worth it? If you only have a couple of pots and trays, you might not need a full greenhouse. But, there are mini-hothouses that have one or two shelves which are perfect for beginners. You will see that the benefits are greater than the losses if you buy one. 

1. Protected & Warm Environment

One of the most important benefits of a greenhouse is keeping your plants warm no matter the season. Letting any flower type or pot outdoors subject to weather can destroy it. When the UK gets the harshest showers with cold temperatures in the bleak midwinter, you’ll love having a greenhouse. You have full control of the climate, sun exposure and damage your plants receive.

2. Fresh Fruits and Vegetables

Another nice reason to consider greenhouses is that you can bring your own fruits and vegetables to the table, no matter the season. Planting them on the ground, exposed to rain, hail, or even rodents passing by your yard, can ruin your vegetables. With a greenhouse, you safely store them in a walled space that shuts tight and keeps unwanted friends away. It’s a cost-effective and environmentally conscious way to have organic foods off your own shelf. No more passing through the produce section in the supermarket!

3. Off-Season Seed Planting

Want to grow mangos, cantaloupes or other exotic fruits and veggies? Why spend any of your hard-earned money on overpriced tropical fruits in the grocery store? A greenhouse can let you seed any plant type or fruit type through the whole year. You can pick up the seeds from a florist and enjoy anything you want, even on off-seasons. Let those white jasmines bloom right in time for Christmas!

4. Insect-Free Planting

Ah, insects! Of course, those little monsters crawling or flying around the garden can give you a headache. There’s nothing worse than waking up to a pest-attacked flower. All that hard work, love and care gone to waste! But, a greenhouse can prevent those annoying pests from coming close to your plants. Any traditional greenhouse is shut tight all around so that no insects can find their way to pots and plants. There are some times that it can only really happen when you enter or open the greenhouse. When tending your plants, you might see some bees, wasps or butterflies coming to check out the scene. Still, there’s a much lower chance of that than when you leave the plants out in the open. 

What to look for when buying a greenhouse

Considering how much time and effort you will put into making the perfect setting for your plants, take some time to review the most essential features. These are going to give you an efficient space that allows healthy plant growth. We’d hate to see you picking the wrong choice. So, look for these features when buying, and you’ll be reducing your environmental footprint in no time!

1. Type

The greenhouse type you pick matters because you want one that your garden can accommodate. The most common ones are outdoor use, but there are some options suitable for indoor use. There are three different types available to match any home size. You can pick between a traditional freestanding greenhouse, a lean-to or a mini hothouse. It all comes down to your garden’s size and the level of gardening you want to tackle. Want to find out more about the pros and cons of each? Keep reading below!

2. Material

The second most critical decision you have to make is what material you want your greenhouse to be. There are some small-scale greenhouses ideal for home use that use plastic. This is a very popular choice as they have low-cost polycarbonate panels. These are very easy to assemble with minimal effort and come in a complete greenhouse kit

Another high-end material is glass. Glass greenhouses are probably the first thing you think of when someone mentions the word. It’s a traditional greenhouse but larger and requires some tools and effort to assemble. Natural light comes in throughout the whole greenhouse, but you should expect a higher price on this material. We talk about the positives and negatives of each material type in a dedicated section further down. 

3. Frame

What’s the point of wanting a sturdy and weather-resistant greenhouse if the frame is not durable enough? Look for the best frame options available to ensure a long-lasting and heavy-duty choice. You can find strong and reliable frames in many different material types. The most common ones are wood, aluminium, steel or galvanised steel bases. Our buying guide goes in-depth on frame materials if you want to find out more.

A top-quality greenhouse frame improves the product’s longevity. Wood gives a rustic look but needs treatment so cost could add up. Aluminium and steel are heavy-duty and stand firm against bad weather. Galvanised steel is the sturdiest of all and, for that, costs more. 

4. Size

The greenhouse’s size should relate to your home space and what you plan on putting inside it. If you want to fill it up with many plants, veggies, and flowers, you have to buy a larger size. Want to keep it indoors? Go for a smaller size that is not too tall to take up the whole wall. The options are endless, with compact mini-hothouses no more than 60-90cm tall to larger ones for spacious backyards up to 2.5m. Are you stressing out about space and limitations? We’ve added a section to guide you through the various sizes available, so don’t worry!

5. Proper Ventilation

You should always have a proper ventilation system in your greenhouse. From simple to luxurious greenhouses, they all have some system to bring in airing to your plants. After all, what do plants need? Oxygen! They are living, breathing organisms begging for your attention. Vented windows and mesh panels let more air in for smoother temperature control. That way, you can prevent humidity, moisture and fungus buildup on your plants.

Whether it’s roof vents, neat accessories like automatic vents or a simple zipped roll-up door, you can find a solution to fit any budget. The most common ventilation system for home use is a mesh panel, especially on plastic greenhouses.

6. Shelves

Regardless of the greenhouse type, always prefer one with at least one shelving unit. Most standard little greenhouses have at least one or two tiers to hold pots and flower trays better. Instead of leaving them directly on the ground, you should get a shelved greenhouse for ease of planting and maintenance. Not to mention that the plants will have better access to direct sunlight. 

The most common shelving options are either two or three-tiered shelves. You could even go bigger with four-tiered shelves. Some larger walk-in greenhouses have shelves on either side or just one side. That allows you to keep potted plants on one side and fruits and vegetables on the other where the headroom is taller. 

What are the different types of greenhouses?

Want to place your greenhouse in the middle of your backyard? Looking for a mini version that fits your apartment? Whatever the case, there are three popular types of greenhouses that most people go for: freestanding, mini or lean-to greenhouses. Each has its positives and negatives so let’s go through them. 

1. Freestanding

A freestanding greenhouse is the most traditional one that you have probably run across. Most have the standard horticultural glass look with an apex roof and allow sunlight to shine through easily. They are square-shaped like a home and have a sliding door or double doors. There are different sizes of freestanding greenhouses to fit any outdoor space. 

One of the biggest positives to this type is that you can put it anywhere you want in the garden. The four glass sides let light in from all directions so you can play around with placement. Also, the variety in choice is so much that you will find one that won’t make your pockets hurt. Another nice thing about this type is that they are spacious and allow you to walk inside them. 

When it comes to the negatives, freestanding greenhouses might let light in, but their exposure allows heat on hot summer days much faster. Also, the upkeep costs add up significantly. 

2. Lean-to Greenhouses

These greenhouses are perfect for taking advantage of side walls or garden areas that you’ve left half empty. They are a middle choice between freestanding and mini-greenhouses. They cost almost as much as freestanding but don’t occupy as much space. That makes them ideal for small to medium-sized gardens. 

Its most vital benefit is that it has three sides that are wind-protected as the one side touches on a wall. They are very smart solutions to fill up any blank spaces that don’t have any other purpose. They minimise energy waste and give better temperature control too. The biggest downside is that because they are mounted against the wall, you don’t have unlimited access on both sides. Also, the light comes in from three directions instead of four as in freestanding ones. 

3. Mini Greenhouses

A mini hothouse is perfect for apartment owners or someone with limited space. They don’t take up too much of the patio, balcony or wall and come with handy shelves. They are also inexpensive and won’t break your bank. 

On the positive side, they are compact and ideal for small areas. They also cost way less than freestanding ones, and most mini hothouses have detachable parts for effortless storage. A drawback is that they are not walk-in, so potting and maintenance could be trickier. Also, they don’t have as tall a headroom to allow plants to grow as much. 

What size greenhouse should you choose?

Getting overwhelmed if you can fit it in your space? You don’t have to worry about a thing because there are options to match any space. Who says that greenhouses are only for those living close to nature? You don’t have to be living on a farm to have your own greenhouse. Even a city apartment can have a mini hothouse in the house or on the balcony. The mini ones are as small as 80-90cm high and 45-60cm wide.

The bigger the greenhouse, the more you produce you can grow, get an endless flower supply and give back to mother nature. A solid and common size for plastic greenhouses is 1.30m height by 100cm width and 50cm depth. 

Have a large backyard, and size is a non-issue? There are even bigger ones that are 2m in height and 3m wide. Those will most likely be walk-in greenhouses with shelves and enough space for large pots and trays.

Is glass or plastic glazing for a greenhouse more durable?

The most common image we get of a greenhouse is a glass one. But, there are other glazing materials, including plastic. A glass greenhouse is pricier than a plastic one and risks damage more. For that reason, in a rough hailstorm, it could run some safety hazards. Plastic is unbreakable and a very inexpensive solution. These greenhouses have polycarbonate sheets

A polycarbonate greenhouse allows plant growth but, after a few years, loses that clear polycarbonate look. Another solution can be a toughened safety glass on your plastic greenhouse. It’s heavy-duty material and puts glass greenhouses to shame because even if it breaks, the pieces are softer. But, for a little greenhouse, you will see the price skyrocket at least by £100-200. 

All in all, for home use, we recommend a plastic greenhouse. These are budget-friendly, durable and weather-resistant choices that won’t cost too much. They also come with a protective cover that improves the greenhouse’s longevity and keeps the frame rust-free.

Wood or Aluminium Frame: Which one is better?

The majority of greenhouses have a metal frame, either aluminium or steel. But, there are some unique and stylish wooden frame options too for a slightly upped price. Sure, they are very beautiful and a nice centrepiece to your garden. Do you want it for its beauty or quality, though? Let’s compare the two, and you can decide which one is better. 

Wood

Wood is not the most common greenhouse out there, but some prefer them because they are natural-looking and add some character to your garden. There are different wood types to pick from, like cedar, pine, oakwood, ash and hardwood. All wood types need treatment, so keep that in mind. 

To the positives, wood doesn’t stand out as much as a large piece of metal in your backyard, giving you a subtle and decorative look. Also, wood is a natural insulator, far better than steel and extremely superior to aluminium. Want to customise your greenhouse? You can paint wood to any colour of your liking. 

On the downside, wood is a pricier material because it’s natural and requires more upkeep and treatment. It’s more likely to rust or collect mould and mildew. So, you should have a care routine in place. 

Metal

Metal frames like aluminium and steel are more popular and greenhouse standard materials. Because they are so popular, you can find many different sizes and types to fit your personal preference and budget. They’re lightweight and portable to carry around the garden.

On the plus side, there are lots available on the market, so they’re not too expensive. Aluminium and steel is a heavy-duty and durable metal which doesn’t need too much maintenance. Even more so if it has a powder coating on the frame. Also, most metal greenhouses come in detachable parts, unlike wooden greenhouses. That makes them far easier to assemble without strain. 

The biggest drawback to metal frames is that they don’t have as good insulation as wood. Also, because they are lightweight, it’s more likely that they could collapse if bad weather hits. Many models come with pegs, pegging points and anchors to securely hold them in the ground. 

What’s the best position for your greenhouse? 

First of all the big question is this: Are you keeping it indoors or outdoors? After you’ve answered that, you can start thinking further about placement. We wanted to share some of our expert tips on the best greenhouse placements around the garden or home. 

  • Always place the greenhouse in direct exposure to the sun so that the most light can go in.
  • Avoid areas that are too out in the open as there is a higher risk of a windy breeze hitting your greenhouse.
  • Keep it away from walls (unless it’s a lean-to greenhouse) so that you can clean it around all the sides.
  • If you’re keeping it indoors, don’t place it in your bedroom or frequent hangout areas. Plants need oxygen but so do you! You want to store it in an area where you can give light to your plants either naturally or with some accessories. A basement could be a great use of unoccupied space.
  • If placing outdoors, stay away from trees and other high-risk areas that would damage your greenhouse if they landed on it.

How much can a greenhouse cost?

Greenhouses are for sure a gardening upgrade, but anyone who likes to take care of their plants already invests a lot of time on the task. The most premium materials will up the price, but you can find affordable choices too. Our top 10 greenhouse choices give you options that fit any budget.

Affordable

You can find inexpensive greenhouses that are smaller in size and built with more accessible materials like plastic. These are compact and lightweight, which makes transporting them around the garden easier. You can find low-cost options for as little as £30. These come with a roll-up zipper door and a couple of shelves for healthy plant growth. The panels are breathable and let airflow in very well. Most small greenhouses are no more than £50 to promote a green thumb in a friendly price range. 

Premium

Experienced gardeners can agree that premium build materials and a sturdy frame can give you a long-lasting product. So, aluminium greenhouses or steel greenhouses have an increased resistance to wear and tear as well as severe weather. That means that they are pricier too than other materials. A larger size also ups the price as they fit more plants inside. You can find high-quality choices ranging between £100-300, but there are even pricier ones going all the way up to thousands of pounds. For home use, we recommend sticking to the lower scale of the high-end price.

Closure

Are you ready to start setting up your home garden? With the best greenhouses, you can improve your plants’ life and let them grow in a controlled environment away from bad weather. Any green thumb can agree that the taste of a home-grown vegetable is far better than any store-bought one. So, pick the greenhouse type that matches your needs and budget and start seeding!

Our buying guide has given you answers to the most common questions that any level gardener has. Rain or shine, nothing can stop you from getting your hands dirty and into some flower potting. Wait no further!
