The Gardyn Sprout Nursery has a built-in cover and tray to block access to its water. We recommend preventing your pets from drinking water out of germination trays containing 圜ubes so they do not accidentally ingest any fibers. This danger does not apply when handling 圜ubes. Inhaling rockwool fibers is only dangerous when you are handling and manipulating rockwool in large quantities. Reused rockwool can be especially helpful to increase water retention in gardens or flower pots that otherwise quickly go dry. Rockwool does not contribute harmful chemicals to the environment, and you can add rockwool from retired 圜ubes directly to the ground without worrying about negative environmental consequences. They are not compostable, but remember, neither are rocks! Rockwool is composed of natural mineral elements melted into fibers and woven together. Rockwool holds water well and does not dry out when stored for prolonged periods of time, while also retaining its structure when wet, even after many months on your Gardyn! The interior of 圜ubes is made up of rockwool, a natural, rock-based growing medium.

You'll notice a slight visual difference between the two casings, but it will not affect your 圜ubes' growth. Both casings are compostable in industrial composters. We are transitioning all of our 圜ubes' casing from a corn-based plastic to a more sustainable, tapioca-based casing. Garydyn 圜ubes are made up of three parts: the casing, rockwool, and seeds. The Gardyn 2.0 lid top is made from bamboo wood. The Gardyn 3.0 lid top is made from Hevia wood, also known as rubberwood, a type of hardwood tree in the maple family. The Gardyn's columns, yPods, Pod Caps, and water tank are made of food-grade, FDA-compliant, ABS plastic, commonly used in medical-grade equipment and children’s toys. Gardyn Columns, yPods, Pod Caps, & Water Tank We strive to build the Gardyn (and its packaging) with sustainable materials whenever possible, and we are continually testing our materials to make improvements.
