I built a new clone box, wich i put 7 x 20w compact flouro's. On the lamp package, it says, each globe is 1100 lumens. That's a total of 7700 lumens. In the FAQ'S, i found a lumens calculator, but am not sure if it is correct, if i use that calculator, i come up with 10500 lumens. It says for flouro's, wattage x 75. I have 140w of compact flouro's, x 75 = 10500 lumens. Or for HPS, wattage x 100 = lumens. Is this correct? How many lumens are good for clones? My main grow hut has 1x 250HPS overhead, + 6x 20w compact flouro's for side lighting. According to the lumens calculator, thats 34000 lumens all together. Is that enough for 2 plants in a 3' x 3' x 6' high space? Full hydro. Anyone know how to calculate lumens, and how many needed for veging and flowering? I have had good results with just the 250 hps, but today added 6 compact flouro's to the walls for side lighting, my plants are to bushy, with no light getting to the lower plant, so hopefully the side lighting will help.
