Did you dredge up this old thread just to tell them they are wrong, and your light stressed plants are doing just fine?Scientific studies at various universities on cannabis have shown the greatest yield and potency occurs at about 1500µmol (the sweet spot) but cannabis also continues to increase yield and quality all the way up to 2000µmol and higher but after 1500µmol you experience diminishing returns.
