Humidity grids are just the thing for growing finicky plants — and drying your boots quickly! The secret to growing many plants, like orchids and African violets, is a humid environment. Here's an easy, economical way to humidify the surrounding air: Place these grids in the waterproof trays of our Light Gardens and arrange plants on top. Keep water in the trays and as it evaporates it will increase humidity around plants — the grids elevate plants above the water level so roots don't rot. Grids may also be placed inside Boot Trays to elevate boots above mud and melting snow for faster drying.
