Par-Gro 315W CMH 3100K - ceramic metal-halide lamp for growth and flowering

Each 315 watt lamp produces light equivalent to 500-600 watts of traditional MH / HPS light. As these lamps use less than 350 watts of power , this means you can save up to 40% on your power bill while covering the same area. Most growers who use CMH lighting get higher yields and a big jump in quality.

CMH lamps are very good at growth and flowering, especially those with a warmer color spectrum (around 3000K), but no better than HPS in the red spectrum area.

• Ceramic metal-halide grow lamp
