All three models are made with the same aluminum frame structure and have the same shape. The Mythos, Hybrid, and Harmony Greenhouses all have the same Snow Load (75kg/m² | 15.4lbs/ft²) and Wind Resistance Capacities (90km/hr | 56ml/hr).
They differ in their panels, and therefore their light transmission, heat retention and appearance.
The Mythos is made with twin-wall polycarbonate panels for both the walls and roof which creates a more insulated greenhouse and higher heat retention. The panels are more opaque than the other two model and you can only see the outline of what is inside the greenhouse when looking from the outside.
The Harmony is made with clear polycarbonate panels for both the walls and roof which creates a less insulated greenhouse and allows for more direct sunlight. The panels are more transparent, and you can easily see what is inside the greenhouse when looking from the outside.
As the name suggests, the Hybrid is a mix between the two, with twin-wall polycarbonate panels on the roof, and clear polycarbonate panels for the walls. It is semi- opaque on the roof, and semi-transparent on the walls. You can mostly see what is inside the greenhouse when looking from the outside.
