Hi, according to this lumen/par converter “https://www.waveformlighting.com/horticulture/convert-lumens-to-ppf-online-calculator” 10k lumens from a 3500K led and 10k lumens from a red or blue light led, produce different PAR values.
For example: 10k lumens of a 3500k led low cri produce 160 umol/s and 10k lumens of a 450nm led can produce 1155 umol/s al (7x more PAR/PPFD)
So my question is the blue led has more PAR that 3500k led? (based on this calculator)
Another thing to think, only if the last was true, one simple 100w of red or blue led is sufficient for the most of grow tents!!!
