looking pretty good for the first grow!!! Smell... it depends on what strain you are working with that will determines if your going to just beable to use ona or a carbon filter to! you can make liitle cheap carbon filters by buying carbon from the pet store and puting it in to a pouch made out of peace of screen, then just stitch the sides up with fishing line and tape it to the inside of the pc box fan. ghetto but it works not to bad. I do it cause I have light traps and I slide them in to the first part of the light trap to hold it. Thanks for checking me out and good luck!
