  5. Dr Bugbee, I have watched this video at least 5 times by now. I am 54 so it takes a bit more of an effort to remember than it would for me have 35 years ago.

  6. 100-600 watts led 2 ft.
    600-1200 watts 2.5 ft.
    During flower move it up a half foot.
    Always go with a 4000k if you're undecided on color temp. These are good general guidelines for starting. And you can use led shop lights like lithonia at lowes. They're on point now. Full spectrum. The industry changed with led lights
