I know MH or HPS are a brighter light and offer spectrums suitable for growth. However, everyone seems to be leaning toward T5 systems to clone and vegitate in. I has always been my belief to supply MH for growth and HPS for bloom. I would like my plants to reach 2 ft in growth and 2ft in bloom. What do you think?
T5’s are very efficient and provide excellent lighting for the vegetation cycle. If your planning to veg 20 plants or less at a time, I would say use a 4′ -8 bulb T5 light. These lamps provide as much as 60,000 lumen and are very bright. Metal Halide would better suit a person growing on a commercial level.
