I've been looking around online and decided I want to do a grow tent set up with a carbon filter. I've already grown before but now I have to be more careful because last time I did a bit of a "ghetto" grow. Now the problem is I don't know what grow tent to get, and if I do, how do I know the carbon filter I get will fit for it? Can anyone help me with this? I've seen a few "grow kits" here: http://www.htgsupply.com/Category-Complete-Grow-Kits.asp But they don't come with carbon filters so I don't know if they would work together or not... help appreciated.
