Each order of Glow Plants contains 1 Free UV Keychain, however if you are gifting some plants, we suggest picking up additional UV Keychains. Shining UV light directly on the plants in the dark greatly enhances their glow!
The synthesized glowing coating on our plants produces light through a phosphorescent reaction meaning it absorbs UV and converts this energy to visible light with a slow release or "decay" time.
The glowing compound we use to coat each plant is reactive to UV light. Leaving your Glow Plant in a window sill is fine and you will still get a glow at night however with direct UV light for only a few seconds, your Air Plant will glow up to 10x brighter! Higher UV input equates to more intense luminescent reactions!
