This video is the latest and another interview of Dr. Bugbee from Shane over at Migro.
If you don’t know who Shane or Dr. Bugbee are, PLEASE watch. You will be intoduced to some of the most up to date medicinal cannabis growing information available. Shane does/has a gazilion LED light fixture PAR and PPFD maps test on youtube. Dr. Bruce Bugbee is litterally a NASA scientist researcher who’s job it is to help NASA grow food on long space flights and because of it’s sensitivity to light polution, cannabis has played a huge part in his research.
WARNING: watching this video can get you hooked on REAL MARIJUANA GROWING SCIENCE!

Dr. Bugbee has a wealth of knowledge on plant science & lighting. He is the creator of the apogee light meter/par sensor/ppfd reader that most of the light testers use to create PAR maps.
