Here is a comparison of the Florida sun in October at 3:00PM, compared to a DE Genesis HPS bulb. The Lighting Passport spectrometer was four feet from the DE HPS bulb which was on for 20 minutes before the measurement. The comparison is bench marked to the Medical Plant curve which is the white line.
What are the medicinal benefits of adding or increasing the UV end of the spectrum the last two weeks of flowering?
How beneficial is it to have consistent blue light available to your plants for their entire life cycle?
How can we find the most economical way to provide this extra light to our projects?
