Veg/cloning room is 7x8' and both flowering rooms are 6x7'. Each flowering room has its own fresh air supply and exhaust into my veg room, cleaned and exhausted outside. My entire set up came from the pages of GP. I spent at least 6 months planning before I started the project, a month researching strains to grow. I know, I'm such a nerd!

Thanks for comments, if you see anything that doesn't look right please speak up. You all make me better.
