Grand Gro Greenhouse (Extension)

This is an extension kit to the Grand Gro Greenhouse, extending the greenhouse by 2,86m at a time.

It includes two roof vents and one side louver vent, with the base frame extension.

6mm Polycarbonate panels and 1.3mm thick aluminium frame – the same as the Grand Gro kit

This extension can be added on at the time of assembly of the main greenhouse, or can be added at a later stage to lengthen the greenhouse.
