Nimbus is an innovative self-watering planter that does not require any electronic sensors and control systems. Nimbus adjusts the amount of water the plants get, depending on the specific environment they are in. As the plants grow larger, or as humidity and evaporation levels change, the water supply will change accordingly. Alternating natural dry and wet phases prevent fungal infestation. The two-part reservoir holds up to four litres of water, sufficient for up to four months of watering per fill.
