We recommend these trays because of great quality and elegant design. They perfectly fit in our sprouting shelves. Excess water is drained through the holes in the bottom of the tray, protecting the roots from rotting. This tray is combined with the saucer, which prevents water dripping onto the floor. The grow tray is available in 2 sizes. These trays are made of recycled plastic. The grow tray is maintenance-friendly and easy to clean. It can be placed in direct sunlight. All products feature a UV-filter to prevent colours fading. The tray is suitable for temperatures to -40 Celsius.
