Protecting your leafy or micro greens from direct sunlight or harmful UV rays is an essential consideration whether you are a hobby gardener or one that takes propagation seriously. The BillyOh Harvester takes its form courtesy of its solid (and popular) Twin-Wall Polycarbonate glazing, the recommended material for greenhouses because of its great deal of uses and advantages:


  1. The way it’s built, this glazing diffuses sunlight and spreads it out, keeping the developing plants inside protected against excessive heat that may have a negative effect on their growth.

  2. Its reflective insulating properties reflect the heat from the sun off the building, keeping the inside generally cooler and more conducive for growth.

  3. Its UV coating not only protects the plants against the harmful element but it also safeguards the material itself, therefore improving its durability and strength.

Tough Aluminium Framing

The BillyOh Harvester Greenhouse’s framework is made from tough aluminium. This low-cost material takes pride in its light weight and firm build allowing it to withstand daily wear and tear.


The backyard greenhouse 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.

Spacious Internal Area

Spacious Internal Area

The Harvester comes in 2 extra-wide sizes—10 x 8 and 12 x 8—and can accommodate a variety of plant sizes such as your hardy plants, leafy greens, micro greens, herbs, seasonal crops such as lettuce, peas, and carrots.


The greenhouse can be used as a seasonal plants store for your patio vegetables, a summer propagation house, or a fall propagation building for winter plants.


Its wide walk-in orientation fully accessible through its sliding central double door entrance makes for an easy and stress-free vegetation all year round.


Organically grow your flora and switch from processed and artificially-grown produce to healthier choices—the BillyOh Harvester, being the infallible garden companion that it is, helps you achieve that right in your backyard.

On-roof Ventilation

The BillyOh Harvester Walk-In Greenhouse features 2 opening vents installed in the roof providing the building’s interior with proper ventilation. Effective temperature control in greenhouses is key to having the highest-quality produce harvested in consistent quantities.


Proper and unobstructed airflow within the propagation house ensures your plants get the recommended supply of oxygen and carbon dioxide crucial to plant growth.


The 2 opening roof vents are strategically placed on top of the building to evenly distribute airflow and regulate humidity that can make or break the development of the plants.

Comprehensive Instruction Manual

Comprehensive Instruction Manual

The Harvester comes with an easy-to-follow instruction manual that helps you put the building together in a matter of hours. We made the instructions especially simple yet step-by-step in nature to give you a better time to revel at the great features that this structure is built with.


And another good thing is, no special tools are needed to get the job done right. Just a few handyman skill and of course, a copy of this greenhouse’s manual.
