The Sunmaster 10K 600w finishing lamp is a great way to improve final quality by introducing deeper blue spectrum at the final stages of flowering.
A broad spectrum of light is ideal during all stages of growth, however when using HPS this is a difficult to achieve. Therefore swapping out your predominantly red spectrum HPS lamps at the end of the cycle is a great way to improve your flowers.
Although doing this will sacrifice a small amount of yield, it's a trade off many experienced growers have made for decades.
