For the most part, grow lights are resistant to moisture, but you will want to pick carefully if you need an option for a room with a higher humidity level or a hydroponic harden. Some grow lights, like the SANSI 70W Plant Light, come with an IP66 rating, which certifies the product as both water and corrosion-resistant. It’s natural and necessary for you to spray your seedlings with water to speed up their growth, and this moisture resistance can help you avoid any problems with your product.
