  1. Hello this is my frist time growing and wanted to know how much 2 mh 400 watt lights are going to cost to run them 18 hrs a day , they say that they draw 2 amp each a 220 volts also i have 2 hps 250 watt lights are these going to be enough light for the buding process in a 4 by 6 foot area any input would be nice Thanks
     
  2. ideally you need approx 2000-3000 lumens per sq foot......the 2 MH's will give you 72,000 lumens.....good enough for your space, however the 2 HPS's will only give you 56,250......enough as well however it would be better if you had a 600w HPS........but the 2 you have will do the job quite well.......either that or don't use the entire room to grow, you've gotr enough room in ther for approx 24 plants as for how much power they'll use!!....try this handy little link......Peace out.....Sid
