With the Growers Choice 3K 315W Single Ended CMH lamp is a powerfully efficient indoor garden lamp that more closely matches sunlight than any other lighting system available.

  • Contains precision gasses for enhanced spectral output
  • Generates much less heat than high-pressure sodium (HPS) and metal halide (MH)   
  • Utilizes a full phase spectrum that is designed to be used in all stages of growth but optimized for bloom
  • Growers have reported tighter inter-nodal spacing and better yields on flowering plants

With a color rendering index of 90, the Growers Choice 3K spectrum is extremely close to natural sunlight but with modest blues, extra red, and UV light to serve your plants photosynthetic needs — especially during the flowering phase increasing yields and resin production. This makes the Growers Choice 3K 315W Single Ended CMH lamp the perfect grow lighting fixture for your vegetation to thrive under.
