I was wondering, at what point does adding light start to have a diminishing return effect? I've read plenty of minimum lighting requirements, but where is the approx. per plant sweet spot? With all other variables the same, say you have 10,000 lumens on a plant that makes 1 ounce, 15,000 lumens on a plant that makes 1.5 ounces, 20,000 lumens on a plant that makes 2 ounces, etc. What I'm trying to say is, is there a direct linear correlation between the amount of lumens a cannabis plant receives and the yield, or is there a point where you start to get diminishing returns? I'm assuming it's the latter. Say at 30,000 lumens you yield 3 ounces, but at 40,000 you only yield 3.5, at 50,000 3.75, and so on and so forth. Has there been any documented experiements that provide an example of what I am trying to figure out, or does anyone have personal experience with dimishing returns from too many lumens?
