Greenhouse 4 ft Extension Kit - to fit 8 x 8 Balance Greenhouse

Regular price $560.00

This 4 ft Extension Kit has been designed to be added to our 8 x 8 ft Balance Greenhouse.  This Extension Kit is the ideal solution for those gardeners’ who require more area to grow their plants, fruits, vegetables etc than the basic 8 x 8ft Greenhouse provides.

There is an added vent for increased circulation on each kit and each kit easily attaches to our existing 8 ft series Greenhouses to increase the overall length by 4 feet/120cm for each kit purchased.

The 4ft Extension Kits can be sequentially added to 8 ft Greenhouses to increase the overall length up to 20 ft (614cm) long. To increase 8 x 8 ft to 8 x 12 ft, add 1 x panel. To increase to 16 ft long, add 2 x panels. To increase to 20 ft long, add 3 x panels.

*We do not recommend adding more than 3 extension kits to the original               8 x 8 ft unit.

**As the Extension Kit is designed to connect between front and back sections of the greenhouse we recommend assembling the extension kit at the same time as the basic unit.
