Setting up a dry tent alongside my grow tent. My 7 autogrow plants are in week 8 and are at slightly different stages I have just purchased an additional smaller grow tent with a humidifier and rotating fan. I also have extra ducting- do I need a carbon filter to dry???
Like others have said, carbon filter just eliminates smells. If you're not worried about the smell, you don't ever need a carbon filter. I hook mine up around week 4 of flower.
It depends. Are you worried about the smell ? Do your plants really smell ? That's the only reason you would use one . So if your worried about that then yes maybe . I don't use one . Hope that helps
