Optional Greenhouse Base with Corner Posts

Place on hard or even SOFT GROUND!

The usual golden rule when erecting a greenhouse is to place it on a hard and level surface so as to keep the greenhouse from twisting or becoming unstable over time.

Vitavia Green Corner Post

If you want to install your greenhouse on soft ground then our optional Vitavia steel bases come with corner posts that you can bolt to the base. These posts are roughly 18 inches long and can be sunk into soil and then concreted in place once your greenhouse is level and square.

Vitavia Green No Corner Post

If you are intending to put your greenhouse on slabs or concrete then you simply don't attach the posts to the base, simple!

For more information please see our assembly video.

Toughened Safety Glass

Toughened Glass is much stronger than Horticultural glass and won't crack. If it does break it disintegrates into hundreds of small pieces that are unlikely to cause injury, unlike Horticultural Glass which breaks into shards. It's heavy weight also means it's the best glazing option for windy spots and the UK in general!

Full Length Glass (Long Pane)

Toughened Glass is long pane, meaning each panel in your greenhouse is one piece of glass. No unsightly overlaps where dirt and grime can collect and no Overlap Clips to worry about.
