Gardening is a hobby for many homeowners and growing your food is not only rewarding but can save you lots of money too. Growing vegetables and your own fruit is a great way to slash your grocery bill while eating tons of healthy nutrients and vitamins. However, if you live in a colder climate, certain times of the year, it’s impossible to keep growing produce and other plants. Greenhouses are the perfect solution to keep your plants growing year-round, even with snow outside.

Building a permanent greenhouse can seem like a lot of work. If you’re looking for something more portable, whether that be because you’re renting, maybe selling your home in a few years, or just want the flexibility of being able to move it if you want to, portable walk-in greenhouses are a great option.

There’s a lot of different types of greenhouses on the market today, especially when it comes to portable ones. There’s a plastic walk-in greenhouse, greenhouses for vegetable gardens specifically, small greenhouses for sale, and just your standard walk-in greenhouses as well.

We’ve gone through and not only explained important information regarding greenhouses and how they work but also listed the best portable greenhouses on the market today.

How Greenhouses Work

If you’re not too familiar with greenhouses, you may be wondering how they even work. Simply stated, greenhouses work by converting light energy into heat energy. The UV rays from the sun enter the greenhouse and are able to be absorbed by the plans in there and converted into heat.

The frame of the greenhouse ends up trapping the heat inside. It’s also important to know that greenhouses can therefore get too hot. It’s important to have a greenhouse with windows, vents, fans, or something built in to release hot air if needed.

Certain plants like certain conditions, so depending on what you have inside your greenhouse, getting a proper heating and cooling system may be beneficial to ensure that your plants are always thriving.
