Hi, what do you think about this product:
http://v-tac.eu/led-lights/lights2/led- ... etail.html
I find it strange they didn't specify the frequencies used for photosynthesis. I have no idea if the product uses 450nm blue or 660nm red SMDs. So, it smells fishy to me, but I'd like to have your opinion.
