  1. I watched a youtube video on lights used for reptiles and birds, i have a 20watt cfl which emmites UVB rays which was used for my parrots but ive now stolen for my grow room,

    the theory is that uvb increases the ammount of cananboids and THC levels, watch the following video


    anybody know anything else on this?
