Water Protection: Currently, the Growcraft has no protective coating against direct moisture exposure. If moisture accumulates near the LEDs damage may occur. Make sure to point any sprays downward and away from the LEDs.
Use of VOC (Volatile Organic Compounds): DO NOT USE VOCs, like burning sulfur, near any Growcraft. This can damage the LEDs beyond repair and is NOT covered by our warranty.

Start Slow – Growcraft lights have VERY high light output and unless your plants are already acclimated to high light intensity, it is best to start slow with the light hanging high and possibly also dimmed. Then monitor plant reaction over a few days and slowly adjust as needed.
