the bulbs in the picture are in no way= 360 watts. they look like 23 watt or so. the package will say something along the lines of 23 watts and 90 watt equivalent. you need at least 50 actual watts per square foot for good results. now I have seen people refute this showing great results w/ as little as 25 watts per sq ft and others say nothing less than 100 watts per sq but as a rule of thumb, 50 watts or more per sq ft works out well.
my 1st grow was done w/ 4 foot floros at about 40 watts pr sq & came out good. the next crop, I added a 400 hps to give me 40 watts of floro and 33 watts of HPS per sq & the results were almost triple the first.
