This self-sustaining plant requires no watering or fertilizing due to hydropearls embedded within it, retaining moisture and providing nutrients. Its current state after a year is demonstrated in the provided image. To make one yourself, use an aluminum tube of 6mm diameter as socket struts, fill with hydropearls as soil, and place inside a 120mm acrylic sphere. Select a slow-growing plant that can thrive in a humid environment. Drill a small hole near the sphere's top to prevent fogging, and keep it away from direct sunlight to avoid condensation.
