I have a 3x3x6 box with a 430/HPS with a hortilux bulb. I was going to upgrade to a 600w box, but $$ has been tight. I figure the difference between the 2 is 18.9 lumens sq/ft. Am I really losing that much yield in not upgrading?
hi valk, 430w hps = 53000 lumens, standard 600w hps = 90000 lumens i could be wrong but in i a 3x3x6 space i think its a little more than 18.9 more lumens per sq/ft. if you can vent a 600 properly, and fit it into your budget, i would go with the 600. :smile:
hello again Valk. i just did some figurin' and you must mean wattage not lumens. Yes the difference in wattage is 18 or 19 more watts, but you will allmost double the lumens with a 600; 53000 lumens is 5888 lumens per sq/ft. 90000 lumens is 10000 lumens per sq/ft! yee hah, it will definitly increase your yeild if everything else is working properly.
