Grow Houses
Maximise your garden's potential our range of grow houses - more compact than a full greenhouse, but perfect to protect your plants for tiered growing.
Our collection of grow houses offers the perfect middle ground for gardeners who need the vertical growing capacity of a greenhouse without the permanent footprint. These space-saving structures feature multiple tiers of shelving, making them ideal for raising seed trays, hardening off young plants, or housing upright crops like tomatoes and peppers. Designed for versatility, a grow house can be easily tucked against a sunny wall or moved around the garden to follow the light as the seasons change.
The primary difference lies in the size and accessibility; a greenhouse is a walk-in structure designed for permanent placement, whereas a grow house is a shallower, space-saving unit typically accessed via front-opening doors or zips. Grow houses utilise vertical shelving to maximise growing space in a small area, making them far more suitable for balconies, small patios, or urban courtyards than a traditional greenhouse.
While both protect plants from the elements, a grow house offers significantly more vertical space. A cold frame sits low to the ground and is best for low-growing plants or hardening off seedlings, whereas a grow house allows you to grow taller crops like chillies and cucumbers across multiple levels. If you have limited floor space but want to grow a high volume of plants, a grow house is the more efficient choice.
Wooden grow houses offer a more permanent aesthetic and superior natural insulation, making them excellent for protecting plants during sudden cold snaps. Plastic-covered grow houses are lightweight, more affordable, and can be easily dismantled and stored away during the winter months. Your choice should depend on whether you want a year-round garden feature or a seasonal tool for spring seed starting.
Absolutely; grow houses are particularly popular for tomato cultivation. By removing the middle shelves, you can create a tall, sheltered environment that allows tomato plants to grow to their full height while being protected from wind and blight-carrying rain. The trapped heat inside the grow house also helps to ripen fruit much faster than if they were grown in the open air.
Because grow houses have a smaller internal volume of air than greenhouses, they can heat up very quickly in the sun. It is vital to manage the temperature by opening the doors or unzipping the cover during the day to provide ventilation. Many of our models include ties or hooks to keep the front panels open, ensuring a steady flow of fresh air to prevent heat stress and humidity build-up.
While not always essential, we highly recommend securing your grow house, especially if it is positioned in an exposed area. Their tall, slim profile can catch the wind like a sail. Most wooden models can be easily screwed into a wall or fence, while lightweight plastic versions should be weighted down with heavy pots on the bottom shelf or secured with twine to prevent them from tipping over in a breeze.
