Rhino Premium 12x18 Greenhouse - Colour Finish

To help promote the perfect air circulation, this Rhino greenhouse is fitted with 4x double roof vents powered by solar powered automatic openers. When combined with our large side louvres (included as standard) they allow cool air to move in through the side louvres and out of the roof as it heats up.

To help promote the perfect air circulation, this Rhino greenhouse is fitted with 2x single roof vents powered by solar powered automatic openers. When combined with our large side louvres (included as standard) they allow cool air to move in through the side louvres and out of the roof as it heats up.

It is essential to have complete control over your greenhouse's airflow, especially in the summer months. You'll want to have the peace of mind that comes with automatic openers.

Each roof vent on our Rhino Premium greenhouses is powered by automatic openers which rise and fall as the temperature changes. Powered by a black cylinder as the wax inside heats up the roof vents are pushed open allowing hot air to escape.

Vents on our Rhino Premiums are also fitted with storm locks, allowing vents to be secured down. This is ideal when bad weather is expected, allowing the entire structure to be made airtight. Note that it is important to disengage the vents before putting the storm locks into position, to avoid causing any damage to the openers.

The ideal temperature for your greenhouse is anywhere between 25-28 degrees Celsius, though it’s worth noting that with the fluctuating UK temperature, along with overnight temperature drops, you’re not going to be able to achieve these temperatures consistently throughout the year. 

This is where having the perfect level of ventilation comes into play. Combining the roof vents, 6x large side louvres and even the large doorway, you can help keep your greenhouse as cool as possible in the summer and warm in the winter.
