The Delta combines a contemporary triangular shape with the advanced technology of a Lechuza planter. Made from commercial quality polystyrene, this tall column planter is UV and shatter resistant. Available with the Delta is an optional drop-in plant liner and sub-irrigation system. The plant liner allows you to preplant your greenery and transport them to the Delta's permanant location. No more lifting of heavy, awkward planters. With the use of the sub-irrigation system, plant maintenance becomes child's play. Simply fill the water reservoir and enjoy your creation as the self-watering Delta supplies your plants and flowers with just the right amount of water to flourish for up to 12 weeks. The Delta's unique design and smart features make it a top choice for any interiorscaping plan.
