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.

itavia 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!

Horticultural Glazing

Horticultural glass is made up of 2ft x 2ft Overlapping panels with a standard thickness of 3mm, and is a popular and cost-effective choice for greenhouse glazing. Gardeners and plant enthusiasts appreciate horticultural glass for its ability to create a bright and nurturing environment that promotes healthy plant growth.

Anodized Silver Frame

Vitavia Anodized Silver Frame

Adonisation is a process that the aluminium goes through to keep it looking pristine and shiny throughout it's life. All Vitavia silver frames are anodized as standard.
