Welcome to our department, where Culture Indoor has composed horticultural lighting kits in CMH version, the latest innovation in lighting with LED:
A CMH lampuses ceramic instead of quartz used for the traditional MH lamp. It is 50% more efficient in lumens and 10 to 20% more efficient in Umol/m² PPFD than MH bulbs.
You should consider switching to ceramic metal halide to increase your yields. Then you'll be a happy grower as you move to the lighting of the future.
