Plastic greenhouses
Start growing today with our range of compact plastic greenhouses - lightweight, easy to assemble, and perfect for seed starting on any patio or smaller outdoor space.
Our range of plastic greenhouses offers an affordable and highly flexible solution for gardeners looking to jumpstart the growing season without the need for a permanent structure. These compact growhouses feature durable, reinforced PVC covers that trap essential warmth and humidity, providing a protected environment for seedlings and young plants to flourish. Perfect for balconies, small patios, or even nested within larger borders, these lightweight units can be easily assembled, moved, or stored away once the summer heat arrives.
While they don't have the same heat retention as glass, plastic greenhouses are incredibly effective for seed starting and "hardening off" plants in the spring. The PVC or PE covers create a humid microclimate that protects delicate growth from frost and wind, making them an ideal entry-level choice for urban gardeners or those with limited space.
Because these structures are very lightweight, it is vital to secure them properly. We recommend placing heavy items like gravel bags or large terracotta pots on the bottom shelf to provide ballast. If your greenhouse is positioned against a wall or fence, using cable ties or a simple hook-and-eye kit can provide the extra stability needed during blustery weather.
While the frames are often powder-coated for durability, the plastic covers can degrade over time if exposed to harsh winter gales or heavy snow. To extend the life of your greenhouse, we suggest removing the cover during the deepest winter months and storing it in an outdoor storage box or your garden shed, or replacing the cover every few seasons to maintain clarity and insulation.
Plastic greenhouses can heat up rapidly in direct sunlight, which can lead to scorched leaves. Most of our models feature a roll-up front panel with zip fastenings; we recommend opening this daily during the spring and summer to allow fresh air to circulate, regulate the temperature, and prevent the build-up of dampness and mould.
Yes, our mini plastic greenhouses are designed for quick and simple assembly without the need for specialist tools. Most models use a push-fit "bolt-less" system, allowing you to click the frame together and slide the cover over the top in minutes, making them a great choice for those who want to get gardening immediately.
To ensure your plants receive maximum sunlight, it is important to keep the cover clear of algae and garden grime. Simply wipe the exterior with a soft sponge and warm, soapy water; avoid using harsh chemicals or abrasive brushes, as these can cloud or scratch the plastic and reduce the amount of light reaching your seedlings.
