thanks man, thats definately gonna help. the budget is a bit low so i think im gonna try with just the LED's first, i mite try get cash together for CFL's and ventilators down the line. its good to know for sure the price of running those hps lamps. il probably give it a go with some small auto-flowers but itl be a while, iv an outdoor setup to look after, might be a while even scroungin the cash for LED's but im fairly dead set on givin it a go now. when i get it up and running il post some progress, hopefully all goes well.

hope your own is going well too
