Question about a grow system

Thanks so much for the help so far guys and Kush, I figured you were probably high as hell when you posted that but it's cool. I'm from NY where they say fuck more than hello....

Anyway, yeah I was told to use the floro lights instead of the MH because MH uses a lot of power right?

I can keep the door open most of the time, not all of the time. So lets say I have AC and/or fans and/or the cooling fan accessory that can be added to the grow light system, that should be cool right? Do you know anything about the cooling fan accessory, is it just a regular fan?

One other thing, do you guys have any experience with biocanna?
