What type of flooring is used in greenhouses?

In greenhouses, flooring is typically made from materials that provide good drainage and are easy to clean. Common options include gravel, concrete, and permeable paving, which help manage excess water while allowing for proper irrigation. Some greenhouses may also use raised beds with soil or specific types of mats for growing plants directly. Ultimately, the choice of flooring depends on the specific needs of the plants and the greenhouse design.
