im working on this project for a client that wants his own “brand” of lighting for his ultra modular-efficient grow rooms we designed/built him. While I don’t really think there’s very much to improve upon the qb we are using, the client wants more. I think adding some small deep or far reds and boosting from 510 to about 600w could be nice starting point. Maybe overdriving to 550 and adding another 100w worth of deep and far red to 650w would be ideal. Any ideas of what small cob chips to use or drivers, led experts?
