What is a 6x4 Greenhouse

A 6x4 greenhouse is simply a greenhouse measuring 6ft wide by 4ft deep. This is a very popular size for a smaller garden, as it takes up less outward space, so dominates the space less, and leaves room for other garden elements. They can be made with an aluminium frame or from treated timber.

Glazing

Toughened Glass

If you are searching for a durable and beautiful greenhouse glazing option Toughened safety glass is the perfect choice. It will provide the clarity of glass without the risk of having to deal with sharp, broken glass in case of an accident.

Horticultural Glass

If affordability is your number one priority you will want to consider horticultural glass. Just beware that horticultural glass can easily break and the small pieces can be dangerous.

Polycarbonate Glazing

Polycarbonate glazing is shatter-proof making it a very safe choice. You will notice that polycarbonate glass is not as clear as the other types of glazing. We suggest avoiding using this glazing in exposed areas.

Accessories

For the vast majority of our range, you will have the option to customise your order and add accessories, and in some cases another sliding door.

Ventilation

The use of roof vents and ventilation in general is very important in a greenhouse. You have the option to add extra windows, louvre vents, and even auto vents to your order. These all help to control heat and airflow. You can also customise your greenhouse gutters.

Heating

For heating, we recommend you browse our greenhouse heaters here.

Shelving/Staging - Maximise Your Available Space

You can customise the shelving included in your greenhouse, to really make the most of the space you have, for the maximum growing space for plant pots, young plants, herbs, tomatoes, peppers, and other vegetables, and any more propagation.
