sorry about that i had been at work all night for 14 hours when i was trying to let u know about lighting.basically if your trying to get a good lumen foot print you could use 2 thousand watts in your flower room or 3, 600's,600 watts in my opinion are more efficient and with out a doubt run cooler.so do the math,1200watts @ 2 lamps or 3 lamps at 1800 watts. for your veg room you dont need as much light coverage because your plants are smaller and compact.some people would do 2 thousands for veg and 3 or 4 for flower, so if your intent is to run 5 lamps "3 for flower,2 for veg "thats 300 watts with better coverage than say 5 thousand watts.you can spread 3 lamps around 2 suit your needs,u get 3 lamps for the same amount of money as running 2 1000's.i say this because when i started i didnt have much info,now im sitting on thousands and thousands of doller worth of things that i either dont need,cant use, because no body really informed me on many things.well live and learn.if your going to run 5 1000 watter your bill just for the lights alone will be 6-7 hundred a month. if you used 5 600's your bill would be hundreds less.
