Sunlight: Partial sunlight or grow light.
Water: 1 to 2 times a week. Half submerge the ball in a container of water and let it sit for 1 minute before removing.
Feed: To keep the plant healthy and encourage flowering, feed twice a month with an all-purpose liquid fertilizer. Mist the leaves as well as submerge the ball in the water containing the diluted liquid fertilizer. Misting foliage with orchid fertiliser will also encourage flowering.
