As a gardener or greenhouse owner, you’re constantly seeking innovative ways to optimize your growing space. One popular trend is using pea gravel as a flooring material in greenhouses. But is pea gravel good for greenhouses? In this article, we’ll delve into the world of pea gravel, exploring its benefits, drawbacks, and everything in between.
What Is Pea Gravel?
Pea gravel, also known as pea shingle or pea stone, is a type of small, rounded gravel typically made from weathered stone, often limestone or granite. The name “pea gravel” comes from the fact that the stones are roughly the size of peas. This material has been used for various applications, including landscaping, drainage systems, and even playground surfaces.
Benefits Of Using Pea Gravel In Greenhouses
So, why should you consider using pea gravel in your greenhouse? Here are some compelling reasons:
