Multi lights

We chatted about this, but for others reading it.. you can custom-tailor an LED's spectrum. you could have one 'like' an hps or cmh and even match intensity for a footprint or more likely a more even footprint with same umol/s provided with zero hot spots. efficacy is greater than hps by a wide margin now too.. you can push 3umol/s per joule, if you want. here's an older study that shows hps may improve bulk, but doesn't increase potency along with that bulk. So you get more mass, but thc doesn't increase with it when compared to buds grown with LED... LED now are much better than the trash they used back then. differences were quite small, if i recall, so possibly statisticalyl insignificant.. i haven't read this in over a year and not re-reading it now, lol. general gist is good enough. cehck out abstract and scroll to conclusions and discussion. https://www.karger.com/Article/FullText/489030
