Humidity tray grids are just the thing for growing finicky plants — or drying your boots quickly! The secret to growing many plants, like orchids and African violets, is a humid en vironment. Here's an easy, economical way to humidify the surrounding air: Place these grids in the waterproof trays of our SunLite 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 our boot trays to elevate shoes and boots for faster drying. Show more
