Any avid gardener will know that a good-quality greenhouse provides suitable conditions for growing all fruits, vegetables, herbs and plants that they wish to cultivate. Our BillyOh Polycarbonate Lean-To Greenhouse is a great example of an efficient, high-quality greenhouse!

Boasting a tough, rust-proof aluminum frame, this greenhouse unit is designed with weatherproofing in mind, made with aluminium frames and brackets with a galvanised steel base. This feature alone guarantees the building to last for years, keeping your produce fresh and healthy for as long as required.

When purchasing a greenhouse, a proper ventilation system is crucial. Otherwise, a greenhouse can easily overheat, wilting your vegetables, fruits and flowers. 

However, this shouldn’t be a concern with our Lean-To Greenhouse, as it features an opening roof vent that allows your plants to receive the optimum amount of airflow. Similarly, the design includes a water gutter that ensures an efficient drainage system inside your greenhouse.

best greenhouses (2020)

Instead of traditional glass, the BillyOh Harvester Greenhouse has been designed and built using twin-wall polycarbonate glazing. The glazing’s role is to protect your plants from excessive levels of heat while at the same time, providing a shield against any adverse weather conditions which may otherwise hinder growth.

The polycarbonate glazing also has a UV coating, contributing to the protection of the plants, whilst also improving the durability and strength of the glazing. Another key feature of this greenhouse are the two opening vents, installed in the roof of the greenhouse.

The Harvester is available in 8×12, offering plenty of interior space for you to grow numerous plants, vegetables, herbs and more! It has an extra high roof, making mobility inside the greenhouse extremely easy – perfect for tending to your plants without the worry of any additional issues.

Finally, the frame is made from tough aluminium, featuring a lightweight yet firm build that helps to ensure the greenhouse can withstand daily wear and tear. The greenhouse frame is also rust-free, allowing you to focus on gardening duties, as opposed to maintenance worries.
