Hydro Hut

I was thinking about getting the Hydro Hut Deluxe with 2 600 watt lights. Will the electric bill be expensive if I keep the light cycle on 18/6? I think the 2 400 watts wouldn't be enough light to get top quality buds like I need. Any suggestions?

2 600... where its going to be hot in there!

THey recently had a batch of bad hydro huts i had one butn i sent it back and got the new one... it's unopened and ill dish it off for 250 because my closet work fine.... it.s the 4x4x7
