Groasis plant cocoons

23-02-2021 - Since 2003 Groasis has improved the functionalities of the plant cocoons each year through introducing a new version. The model 2020 - the Waterfilter Boxx® - can even be used to plant trees with sea water that is filtered to fresh water without using energy or needing maintenance. The plant cocoons are extremely successful and each year we have been able to bring the costs per planted tree down in order to help you reach the best results with the lowest possible costs. If you want to be sure of saving water, have great results at low costs, then buy the original plant cocoons of Groasis here!
