UVB lighting

Hey there.. to be specific... UVB is harmful and before thinking of supplementing it ; do complete research on its harmful effects. Secondly they do help. Most google search shall get you the answer ; and cutting it in short ; it does increase thc production as long as right spectrum (310nm) is used. Also it is not cheap. One of such light is migrow310 uvb and gives fantastic results. Would recommend using it for 2 hours daily and making the plants feel solar noon. Also for it to be succesfull ; consider it supplementing at last few weeks of flower ; as some say it does affect the yields negatively. Would love to see your results if you do use it. Happy growing mate.
