Spectrum Control System:
With two Spectrum Controllers on the front side of the 300W Spectrabox Gold, the output of the light spectrum for growing and flowering can separately be adjusted.

During early growing stage only the Spectrum Controller for the blue grow sections needs adjustment. The Spectrum Controller for the is flowering section can be switched off. For seedlings and cuttings start with a light output of about 30% and slowly raise the light output during the growing stage. For 100% light output the plants need to be completely settled. In the last week of growing, the Controller for the flowering section can be slowly set to 50%. In the growing stage the distance between the 300W Spectrabox Gold and the plants can be about 35 cm.

During flowering stage both Spectrum Controllers needs adjustment. The Controller for the growing section needs to start at 100% and can be slowly adjusted to about 50% in the last two weeks. The Controller for the flowering section can start at about 50% and slowly go to the full 100% in about a week time. The distance between the 300W Spectrabox Gold and the plants can be about 35 cm.
