hey guys.. i recently ran a 400w mh for my veg and a 400w mh and 600w hps for my flower(both 120/60's)...running the 400w for a month was only 30 bucks more than last month.. but i was concerned about my bill having both running in flowering.. both lights together for one month was 150 dollars more..but we also had 5 ac units running CONSTANTLY throughout the house instead of 2 and 2 more people living with. so altogether, running both of my lights (o and i forgot to add my cfl's for veg. (4 125w cfls and 2 t8-4ft) was and will be, well worth the money!
if u do tha 400 you might as well pay the extra 20 for tha 600w ballast, get twice the light and still cost just about tha same as running the 400w...in my town, all the 400,600,and 1k bulbs and parts are easy to get. some like the 4 becuz u can keep it close to the plants, but with the 6 u cant keep it close without burning the plants and still get twice the light..im thinking about doing my next batch with a 1000w mh/hps..have a friend that preaches to me about the 1000 and for the grow that im doing (6 plants 7x5x8 room) and the money i spend on lights, ill sell my two and get the 1k and still pay the same as i was running both 400 and 600...so im pretty convinced that the 1k is well worth the money especially after seeing his baseball bat buds..so it all depends on what you have to grow with. size of your room, how much you want to pay and how dank and dense you want your buds
got that master kush and wonder woman...dutch passion is soon to come!!!
