hey im new to indoor growing, iv done a few guerrilla grows but iv never used lights. im looking at a 400w or 600w hps but im getting a bit shocked with what it could look like on my esb bill. for 400w at 18 hours a day its lookin like 30e/month or 60e/2months. for a 600w its lookin like 40e/month or 80e/2months. also i dont have much height in my grow room, maybe 4ft. worried bout how far away the bulbs have to be so as not to burn, obviously will just be growing, small/autoflower/indica strains.

can anyone who is doing something similar to this confirm or deny it?

have also been reading about LED's and im getting very mixed results. it seems like they ruin flowering and for vegative growth they seem to only be recommended as a backup or extra light along with HID's.

Just wondering if anyone has had a personnal experience with these and could shed some light ( ) on this for me?
