Portable Greenhouses and Polytunnels: Flexible Solutions for Small-Scale Farmers

One of the main constraints for farmers in urban living is finding space for growing crops. If you are always on the move, a permanent structure for cultivating any type of produce can be impractical. This is where portable greenhouses come in handy.

Portable greenhouses are lightweight, modular, and sturdy structures with metallic frames and clear coverings like plastic or polycarbonate that create a controlled environment for growing plants.

While portable greenhouses and polytunnels are sometimes grouped together, they are not identical systems.

This article explains portable greenhouses against poly tunnels and highlights their best use cases to help you determine when investing in one can be ideal.

What Is a Portable Greenhouse?

A portable greenhouse is a lightweight, semi-temporary structure designed to be easily assembled, dismantled, or relocated as necessary. These modular greenhouses typically use simple frames, often metallic, covered with greenhouse plastic, and without permanent concrete foundations.

The main standout feature of portable greenhouses is their mobility, allowing farmers to create a micro-garden wherever they go. This way, the structures make sustainable gardening not only possible but portable.

What Are Polytunnels in The Kenyan Context?

As the name suggests, poly tunnels are tunnel-shaped structures made from metal hoops and plastic coverings.

In the Kenyan context, poly tunnels are the most widely used form of protected cultivation due to their affordability and ease of installation. They are a popular structure in small-scale vegetable production, with tomatoes, capsicum, cucumbers, and leafy greens often produced this way.

Just like portable greenhouses, poly tunnels can be semi-permanent and relatively flexible since you can dismantle or modify them without heavy infrastructure. They are typically anchored rather than permanently fixed, which is what makes them relatively flexible.

Portable Greenhouses Vs Polytunnels: What’s The Difference?

While portable greenhouses and poly tunnels have a few similarities, they differ in terms of the intentions of their design.

The primary intention of a portable greenhouse is mobility. It is primarily lightweight, easy to assemble, and easy to move by design, with portability as its core feature. Also, most portable greenhouses are small to medium-sized and are intended for trial farming, urban use, or makeshift situations where one has uncertain access to land.

On the other hand, the arched tunnel structure is the primary characteristic of a poly tunnel. Also, poly tunnels are typically larger, taller, and designed for full crop production. While these arched tunnel structures in Kenya are not permanently fixed and can technically be dismantled, they are not designed for frequent relocation, unlike portable greenhouses.

Moving a polytunnel takes significant labor and may shorten the lifespan of the structure.

When Portable Greenhouses and Polytunnels Make Sense

Portable greenhouses are ideal in situations where long-term certainty is limited, such as in urban living where the farmer may want to bring their garden along when relocating.

These structures are also suitable for season production. You can erect the structure during favorable seasons and dismantle it when the conditions change.

Portable greenhouses can be used to test new crops or explore new markets without committing to expensive infrastructure. Similarly, you may opt for a portable greenhouse if you are operating on a leased land or an informal arrangement.

Key Advantages of Portable Greenhouses

Portable structures can be advantageous in many situations and for various reasons. In this section, we look at the different ways in which you can benefit from choosing a portable greenhouse.

Lower initial cost. Portable greenhouses often come as kits and cost less than permanent structures upfront.
Faster and easier installation. Installing a portable greenhouse is typically faster and does not require elaborate technical skills or special equipment.
More accessibility. Since portable greenhouses can be used by farmers with limited land or who keep relocating, they are more accessible to a wide range of people than their permanent cousins.

How to Decide Between Portable and Permanent Greenhouses

Portable greenhouses reduce risk and allow experimentation, but are generally less efficient over many years. So, if you have a more permanent piece of land or plot and stable market for your produce, a permanent greenhouse may be the better and more cost-effective option.

However, if you have limited space or are uncertain about land access, a portable greenhouse may be a safer and more accessible bet. This is also the case if you have limited experience with greenhouse farming and wish to experiment.
