The Grower’s Choice 500w CMH Lamps are suitable for use in all standard 500w CMH fixtures. Grower’s Choice 500w CMH lamps use a proprietary phosphor coating on the outside of the arc tube to provide you with the richest spectrum on the market.

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.
