Ive always been a 400 type of guy LSY. Never owned a 6, would have liked to, but never have.

As far as tent growing is concerned with HID lights, ventilation and ventilation are your 2 most important variables to control. Exhaust all the way OUT of the room the tent is in if possible. Does no good to dump it into the same room and recycle the hot air back into the tent.

If you can go air cooled, do it. Much easier to control temps.

I have run open wing reflectors in tents and I would get temp spikes up to and into the 90's. It's doable, but you have to stay on top of things 24/7.

I'll answer anything I can, always glad to help someone willing to help themselves.
