exactly.. something like that.. I seen some thing a while ago and can't remember what it was but the were using fiber optics to grow food in a cave or something.. I don't remember why they were doing it or what it was they were growing... but I remember thinking that's the most sustainable way to grow indoors... so if ppl are growing food w/them then someone has to be growing cannabis with it... can't wait to see the 1st set up!!!
