CMH Grow Lamps Offer Full-Spectrum Light

September 12, 2018

CMH lamps offer a solid full-spectrum output, including some UV and far red light. They are available in two Kelvin measurements: 3100K and 4200K. The 3100K lamps are good for growing plants from vegetative to flowering to fruit without switching lamps, whereas 4200K lamps are best for propagation and vegetative growth.

Fruiting crops like cucumbers, squash, peppers, and tomatoes flower very well under a 315-watt 3100K LEC (Light Emitting Ceramic) lamp without any additional red-light sources.
