Howdy to all my new Phriends on this Phorum! This is my first post so I'm still figuring out how the site/forum functions. I am attempting a stealth grow in a closet. I will be using a 400w HPS without the cooling ports on either end. Essentially it is a reflective hood with the bulb. Since there are no ports on the hood, I guess I am going to attempt to vent the hot air out through the cieling of the closet, and bring in the phresh air somewhere around the same height of the light. Was planning out using a couple of inline fans with the adequate cfm's. I've got the layout in my head, but could really use some experienced input on whether or not this will be sufficient with what I am attempting. Should I go this route or should I just go ahead and get a ported hood?
