So Ive got a question, whats better for odor control. Im growing in 2 plastic totes, in my closet but i cant have any smell. Money isnt to much of an issue, i mean i could drop 150 -2 if i need to but i would like to keep it under 100. I wanted to know what is better for odor control, for 2-3 plants. Ozone generators, or Negative Ion Generators. i will also be using a carbon filter, but i want to purchase one of the two for the outside room. Which is better?
