Jul 16, 2026

Hey there, fellow gardening enthusiasts! I'm stoked to chat with you about one of my favorite topics: growing herbs in small polytunnels. As a supplier of small polytunnels, I've seen firsthand how these nifty structures can transform your herb-growing game. So, let's dive in and explore whether you can indeed grow herbs in small polytunnels.

Why Small Polytunnels Rock for Herb Growing

First off, let's talk about why small polytunnels are a great option for growing herbs. One of the main advantages is that they provide a controlled environment. Herbs are pretty finicky, and they need just the right amount of light, temperature, and humidity to thrive. A small polytunnel allows you to create that perfect environment, no matter what Mother Nature is up to outside.

For example, if it's too cold or rainy outside, your polytunnel can keep your herbs warm and dry. On the other hand, if it's scorching hot, you can use shade cloth to protect your herbs from getting too much sun. This means you can grow herbs year-round, even in regions with harsh climates.

Another great thing about small polytunnels is that they're space-efficient. If you don't have a ton of room in your garden, a small polytunnel can be a game-changer. You can grow a variety of herbs in a relatively small area, and you can even stack your planters to maximize your growing space.

Choosing the Right Polytunnel for Your Herbs

Now that we've established why small polytunnels are awesome for herb growing, let's talk about how to choose the right one. There are a few different types of small polytunnels available, each with its own pros and cons.

If you're looking for a large, walk-in polytunnel, check out the Walk In Polytunnels Steel Frame Kit. This kit comes with a sturdy steel frame and a durable polythene covering, making it perfect for growing a large variety of herbs.

If you have a smaller space or you're on a budget, the Mini Polytunnel Greenhouse Kit might be a better option. This kit is easy to assemble and takes up minimal space, making it ideal for growing herbs on a balcony or in a small backyard.

If you're a professional grower or you have a large herb garden, the Large Polytunnel Professional Kit (20ft Wide) might be more your style. This kit is made from high-quality materials and is designed to withstand the elements, making it perfect for growing herbs on a commercial scale.

No matter which type of polytunnel you choose, make sure it's the right size for your needs. You want to have enough space to grow all the herbs you want, but you also don't want to waste space. Measure the area where you want to set up your polytunnel before you buy it to make sure it will fit.
