but i have seen blue leds for sale elsewhere.. i'm not questioning the patent, i'd care less of it, as long as my flowers bloom.. i was soo hyped up actually, on the fact that they sell LEDs in the specific spectral ranges.. but then i came to find out that there are specific lights do the same thing, cus its all about the spectrum.. but i do wanna try out LEDs tho, just gettin up the fundin first
