Sunmaster Cool Deluxe bulbs can provide up to 70% more blue light than standard Metal Halide lamps. Most Metal Halide bulbs have a colour temperature of around 4000K, the Sunmaster is the only Metal Halide lamp in the UK which has a colour temperature of 7200K which is far more in the blue/white spectrum. By providing your plants with this in the vegetative stage will ensure their growth rate will increase, the internodes stay tight so there is no stretching and there is plenty of new shoot growth to give a fuller, healthier plant that is ready and capable of providing and supporting larger yields when flowering.
