Greenhouse Base with Corner Posts (optional)

Place on hard or even SOFT GROUND!

Vitavia Silver Corner Post

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.

If you want to install your greenhouse on soft ground then our 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.

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