Sometimes when I grow a big tree and the main stalk is so much taller than the rest I'll hang a big fat washer from my light right in the center. Then it'll shade that Center bud a little bit cuz it'll blow around in the breeze from my fans it does let light through but it works real effectively for getting penetration down lower when you're too powerful on the top.If you can get 700-1000 umols on lower bud sites (which is optimum without CO2), than 40 inch above where is main cola it would be 2000 umols I guess. And that is way too much.
