i am in my second week of flower with ak48, there has been no smell. i attribute this to this negitive ion generator , i got on ebay for next to nothing, it is a aspenair negitive ion generator. man i tell you i have this thing in my cabinet the plants have shown great growth and no odor i mean no odor, i put my nose up to the plant and nothing. i plan on taking the neg ion gen out of the box for the last 3 weeks of flower, to gain back its odor. i have always used a carbon scrubber for odor but with this thing i might try to disconitue it on my next grow
