The Grower’s Choice 10K 1000W lamp is a high-performance horticultural light source engineered specifically for the final stages of flowering. Designed to be used during the last 7 to 14 days of a plant’s life cycle, this bulb emits a powerful 10,000 Kelvin color temperature spectrum enriched with UV-B light. The addition of UV-B enhances trichome production by triggering a natural plant defense mechanism, which results in increased resin and terpene content, making it perfect for growers looking to boost potency and aroma in their final harvest. This 1000-watt double-ended lamp delivers an impressive photon output of approximately 1,350 µmol/s and emits around 70,000 lumens at 100 hours of use. But if you want to change it up in your grow space, then check the ROI-E420 system, or the smaller 10K 600W SE lighting.
