Each piece of a GreenStalk Vertical Planter is sold separately so you can mix and match depending on what works for you. This top water reservoir is designed for both the Leaf and Original Vertical Planters.

These are great for add-ons, but if you don't already have a GreenStalk Vertical Planter, it's more cost-efficient to order a new GreenStalk than it is to create one from individual pieces.
