The twin-wall polycarbonate glazing is what makes the BillyOh Harvester Greenhouse a perfect addition to your garden! The glazing diffuses sunlight and spreads it around the interior, protecting your plants from excessive levels of heat. At the same time, this helps your plants to avoid any harm from adverse conditions which may negatively impact their growth.

The polycarbonate glazing also has a UV coating, contributing to the protection of the plants, while also improving the durability and strength of the glazing. 

Not only that, but this greenhouse unit also boasts another key feature – this being two opening vents that are installed in the roof of the greenhouse. The two roof vents have been strategically placed on top of the building for even distribution of the airflow and humidity regulation to protect your plants.

The Harvester is available in 8×12. This offers a lot of interior space for you to grow lots of plants, vegetables and more! The greenhouse frame is also rust-free, which allows you to focus on pursuing your gardening hobby, as opposed to wasting time with menial maintenance tasks.
