Hello folks! One question here . I have one 150W HPS (14500 lumen) and 2x 20W CFL ( 2 x 1300 lumen), so all together is 16100 lumen in a 3.5 sq ft grow box. That gives me 4600 lumens per sq ft. Is that good enough or is it more like minimum for growing decent buds. I want my 2nd grow to be bether then 1st where i had 4 sq ft area with only 14500 lumens (that was 3600 lumens per sq ft). Will be there any difrence with such a small amount of lights or 1000 lumens per sq ft more is not good enough to espect much difrence?
