Hey Budmonster -thanks for your interest, in fact im suprised very little to no smell. I am using a carbon rhino pro for one tent will connect it this weekend to the other tent with the T piece. However if i move the plant then thats a definite time odor is released.
For this reason of low odor i think its a wise idea to rejuve. I had some real stinkers in the past namely "super skunk" and i cant have that smell where i am.
