US Patent 10485184 Stack planter reservoir

A stack planter reservoir retains a volume of water to be pumped through a hydroponic system. The stack planter reservoir includes a reservoir base, a lateral wall, a lid-receiving lip, and a planter-supporting lid. The reservoir base and the later wall define a storage volume for water. The lid-receiving lip is perimetrically connected to the lateral wall to receive the planter-supporting lid. The planter-supporting lid supports a single planter or a plurality of stacking planters. The planter-supporting lid includes a pump outlet to allow fluid transport from the storage volume to the planter or plurality of stacking planters.
