Solarium vs Greenhouse

Solarium vs Greenhouse! Which Is More Efficient?

As an avid gardening enthusiast, I’ve always been fascinated by the idea of extending the growing season and creating the perfect environment for my plants to thrive. Two popular options that come to mind when considering this are solariums and greenhouses. 

A solarium is a room addition in which both the walls and ceilings are enclosed in glass. Unlike a conservatory or sunroom, a solarium’s walls are made up entirely of glass. Solariums are designed to be used during all four seasons of the year, as it has thicker walls than a greenhouse, which allows the sun to warm the space even in colder months. They are intended for human use and comfort.

On the other hand, a greenhouse is a structure that is made entirely of glass or thick, transparent plastic. Unlike solariums and conservatories, their primary function is to house growing plants. 

In fact, they often feature regulated climate controls to help manage temperature, humidity, and other factors that influence plant growth. Greenhouses are specifically designed for plant cultivation and protection, providing an ideal environment for various plant species.
