Twin-Wall Polycarbonate Glazing

Twin-Wall Polycarbonate Glazing

The BillyOh Harvester Greenhouse has been designed and built using Twin-wall polycarbonate glazing, instead of traditional glass. The glazing diffuses sunlight and spreads it around the interior, protecting your plants from excessive levels of heat and avoiding them being harmed and negatively impacting their growth. Reflective insulating properties reflect the heat from the sub, keeping the inside generally cooler and a more conducive environment for growth, helping you to grow your plants perfectly!

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

Opening Roof Vents

A key feature of the Harvester Greenhouse is the 2 Opening vents, installed in the roof of the greenhouse. The opening vents allow for proper ventilation to the greenhouse, and allow you to have greater control over the temperature in which your plants grow, meaning you can produce the highest quality growth. 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.

Double Doors and Spacious Interior

Double Doors and Spacious Interior

The Harvester is available in an 8x12 orientation, offering a lot of interior space for you to grow lots of plants, vegetables and more! The greenhouse also has an extra high roof, making mobility inside the greenhouse extremely easy, perfect for tending to your plants without any special issues. The greenhouse also includes sliding double doors. The double doors create a wide expanse, making it easy for you to get in and out of the greenhouse, and space will not be an issue when moving things in and out. The sliding feature of the doors means that the greenhouse takes up minimal space in your garden and you do not need to worry about the open doors blowing shut and being damaged.

Tough Aluminium Framing

The BillyOh Harvester Greenhouse’s framework is made from tough aluminium. This aluminium has a light weight and firm build, allowing it to withstand daily wear and tear. The greenhouse frame is rust-free which allows you to focus on other maintenance duties than patching small parts or crevices that have rusted (before they rust away). Similarly, the propagation house will not rot like wood nor would it easily succumb to the extreme heat of the sun or other harsh external elements.
