This is a 45 minute video from a professor at the University of Utah. It's a great video on the amount of light that cannabis needs and how it affects the needs of every other component of growth. I love science.
It is. I like the 2nd video that followed, on how blue, green, red and far-red affect growth.Must be getting pushed ATM. YouTube suggested this to me a few days ago. Good watch..
