L (Large hydroponic planter compatible with depth sensor)

"L" is a 12.5cm square-shaped hydroponic planter. It is designed for growing herbs, strawberries, leafy vegetables, and other handy-sized plants. You need to water it once a week when you grow "planter-size" plants (12.5cm square).

As the plant holders are compatible with S (small), M (medium), L (large), and XL (extra-large) planter, you can use S for nursery plants and replant them in M, L, or XL after they grow up. You can also use Plantarium (lighting system) to provide compact yet effective lighting.
