10K CMH:
Grower’s Choice final phase 10k-CMH finishing lamp should be used during the last week to two weeks before harvest and is specifically designed to emit photons mainly in the ultraviolet 350-425 nm wavelength. As high amounts of UV light cause damage to plant cells, plants compensate in order to protect itself and facilitate reproduction by releasing more resinous oils which translates into a higher quality yield.


  • For use in any 500W CMH fixture

  • Produces more PAR per watt than standard Metal Halide

  • Richest spectrum on the market

  • CRI of 97 makes this lamp the closest solution to sunlight available
