The Photontek SQ 300w PRO is an excellent new fixture designed for 3’ x 3’ or up to 1m x 1m coverage. It has a cool design, with LED Bars in three concentric squares. This design produces an excellent distribution of light across the coverage area. It features an ideal spectrum for growing cannabis with ample red and far-red light. Because of its spectrum, I ran it through our standard PAR test (400-700nm) and an extended PAR test (400-750nm).
The Science of Horticultural Light is changing! In this review I discuss the latest research from Bugbee, Zhen and others, which looks at the role that Far-Red Light plays in Photosynthesis. Far-Red light is not included in “PAR”, but it is included in the newly defined “ePAR” range. We’ll analyze how the Photontek SQ 300w PRO performs in both the PAR test and the new ePAR test, and we’ll consider the significance of this new science for us as growers!
