Really decent tsw 2000, i have the 3000'n now.. And i really tell the only difference between a 2000 a 3000 "and any better LED" - is the distance you place your light.. That's affecting your thricome production the most, like "sometimes" more is more and less is less, when stimulating the plant with too much light and the production is off, as in "less" you might get the optimal result, I'd come to plant height, something between 60-85CM and the lamp, just quite at the 27,5-33,5cm ~ above "i'd get the really sticky looking things beneath" ;-)
