Product Spec Sheet

The Grower’s Choice 10K bulb is for growers who are looking to maximize yield and resin production, making it suitable for the last 7-14 days of flowering. The 10K contains UV-B light, which is widely known to increase resin production, as the plant forms its own kind of “sunscreen” to protect itself from the ultraviolet light.
