best greenhouse kits to buy in the market in 2020

Never did we expect last year to take such a strange turn. The Corona crisis has made the world a different place. However, it seems more and more people are discovering the joy of homegrown vegetables. A greenhouse will let you take home growing to the next level and enjoy gardening all year long. In this article we’ll discuss the best greenhouse kits to buy this year.

Maybe you’re quite the handy (wo)man and want to build a greenhouse from scratch. If you are an enthusiastic DIY’er, there’s plenty of manuals to find online to start building. If you are like me and prefer to receive a detailed plan and all the parts in one delivery, you’ll find a wide range of greenhouse kits. It will still be cheaper than having a company install the greenhouse for you, but you will need fewer tools and equipment. Delivered to your doorstep, with manuals and customer support you can contact. That’s my kind of DIY.

A special mention goes to the Palram greenhouse kits. You’ll find one in nearly every category underneath. When it comes to budget friendly versus quality, they are the absolute winner in the greenhouse world. A Palram greenhouse kit is affordable, sturdy and we really like the designs. In case you want to research this brand a little more, we have written an entire article on Palram greenhouses.

The perfect greenhouse kit for your needs?

When you’re researching the possibility of placing a greenhouse in your backyard, we realize the number of different styles, sizes and prices can be overwhelming. The perfect greenhouse kit for you will depend on a number of factors:

  • Material – Glass or polycarbonate? A plastic or polycarbonate greenhouse is the most common choice. These plastic greenhouses are easily set up and budget-friendly. However, if you want to go for a more luxurious look and are willing to spend a little more, a glass greenhouse kit can be a great investment to brighten up your yard. Glass greenhouses are very durable and come in beautiful designs.
  • Size – Oh boy… Where do we even begin? Greenhouse kits come in many sizes, they start as small as 4’x4’ and go all the way up to 8’x24’. The most common hobby size is 6’x8’, if you’re looking for a first-time greenhouse kit, this might be a good starting point! Take a look at our article about greenhouse sizes, to find the perfect size for you.
  • Price – A mini greenhouse will cost you less than $100, a semi-professional model can go all the way up to $10.000. In this case, size matters. Glass greenhouses are usually more expensive than plastic or polycarbonate greenhouses. We’ll help you find the best, budget-friendly greenhouse kit of 2021.
  • Lean to or not – A lean to greenhouse kit will be installed against one of the outside walls of your house. The perfect solution when you have a smaller yard or want to benefit from the electricity and water inside your house to easily access the greenhouse. Take a look at our lean to article to see the possibilities of this type of greenhouse.

Let’s walk you through the best greenhouse kits of 2021!

Best plastic greenhouse kits

When we say plastic greenhouse kits, we mean greenhouses with polycarbonate panels or greenhouses with plastic covers. The polycarbonate panels are strong, durable and budget-friendly. The plastic cover greenhouses are portable and light, but less weather resistant. These plastic cover greenhouses are a good solution to protect your plants in the summer, but won’t withstand winter conditions. Our favorite greenhouse kits are definitely the polycarbonate greenhouses, they come in many different sizes and shapes!

Best small plastic greenhouse kits

Looking for a small greenhouse kit? It kind of all depends on what a small greenhouse means to you. Like we said, greenhouses come in all sizes, but we have listed our favorite smaller options below. When you buy a small greenhouse kit, make sure you think about where and when you want to use it. The portables are only suited to use outside during spring, summer and maybe fall, but have the benefit they can be placed inside during winter. A 6’x6′ Palram greenhouse is an excellent starters greenhouse and probably my favorite in this category. It’s big enough to allow you to grow a good amount of plants, it’s sturdy enough to survive winter (and even grow some winter vegetables) and I like the classic look. Ready to start growing?

Best lean to greenhouse kits

A lean to greenhouse kit is a greenhouse you build against a wall or another structure. It only has three greenhouse sides and uses your home or garden shed as a fourth wall. The benefit of building a greenhouse up against your house, is that you can easily access water and electricity from your home. Your greenhouse will be more protected from the elements, as your home or shed already protects it from heavy winds.

The most popular lean to greenhouse kit size is 4’x8′, perfect for enough growing space but not too big (and thus affordable). Another, more expensive, option is to build a large lean to greenhouse, that can double as a sun room. You can install a door from your house and enjoy every ray of sunshine a crisp winter day brings you. Combine this sunroom with a growing corner and you’re ready to go!

Best glass greenhouse kits

While most greenhouses these days are made out of plastic, the original British greenhouses were made out of glass. And to be honest… It’s still the classiest greenhouse option on the market. These Victorian greenhouse kits belong to my absolute favorites, but unfortunately, they do come with a price tag. When you’re looking to add a showpiece to your backyard, that will last you many, many years, these Victorian greenhouse kits are the perfect option for you.

The glass in these kits is safety glass and almost as sturdy as plastic, but it will last you longer. Plastic greenhouses might start to fade over time or the panels can become a little faded. A glass greenhouse is not only beautiful and classy, it’s also durable. What do you think? Can these Victorian kits allure you?

Portable greenhouse kits

Portable greenhouse kits are a budget friendly and compact alternative to glass or plastic greenhouses. Not only can you move them around and find the most sunny spot in spring and a cool spot in summer, you can also take them inside during winter! When we started out in a small apartment in the city, we would use our portable greenhouse kit to grow tomatoes and spices and move it from our balcony to the kitchen.
