GreenStalk Grey Watering Disk is an individual watering disk for the GreenStalk Vertical Planter. It sits between planter tiers to pass water down the stack.
Each tier needs one disk, so a 3-tier stack uses 2 disks, a 4-tier uses 3, a 5-tier uses 4, a 6-tier uses 5 and a 7-tier uses 6, plus planters and a top water reservoir.
