Growers Choice 600 Watt Double-Ended Metal Halide Bulb, 10,000K

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.

• Outputs UV spectra for enhanced resin production
• 5% degradation rate at 10,000 hours
• High quality quartz glass for consistent spectral output and PAR production
• Increases resin production by weight during late flowering

Features:

• Strong UV peaks for increased resin production
• Can be used 25+ flowering cycles before needing replacement
• Use in the last 7-14 days of flowering for optimal results
• Durable quartz glass arc tube ensures long useable life
