Is there any company that makes a smell proof grow tent? What all do I need to set up a grow tent? What I have found so far is I need a carbon filter, inline fans, ballast. FYI I want to grow with mh/hip lights.
Minor air leaks (zippers, cord entrance, etc.) aren't a problem. They're part of the air intake. Fan runs 24/7 pulling air out thru good quality carbon filter. Keep tent in closed room with windows covered with plywood or panda film. A good quality filter is key. Don't buy cheap filter. Pot needs ventilation, so air tight tent isn't feasible. Sealed grows are possible, but require much more equipment (read "money")
Get a fan with a good carbon filter. Don't skimp out on the filter.
The fan will create negative pressure in the tent, meaning the only stinky air that leaves the tent will have to pass through the filter. A quality filter should get rid of the smells. A secondary defense would be to buy a small jar of ona gel and put it in your exhaust ducting.
It's about negative pressure. More exhaust leaving through a fan/carbon filter, less air coming in. Doesn't matter what material your walls are.
In my panda room I have a carbon filter rated at 500 cfm, a fan exhausting at about 480 cfm, and an inline fan bringing in about 350 cfm. Tight negative pressure. No smell.
What these guys said. It's all about that negative pressure. I have a 4" in my tiny little tent strapped to a big ass carbon filter. Sucks in the walls of the tent. No smells until I open it.
Not a chance. Just get bigger fans and move more air out of the area. Dual carbon filters if you're in that much need. Read the guys negative pressure comments. Experience says "No" if no odor is a deal killer. Just preparing you.
