i need help! right, here goes. im 4 weeks into flower with my ice breakers and super cheese, 2 of each, ive had my carbon scrub working 24/7 from the word go, and ive noticed a pungent odour coming from it. its outside my tent, which is 120/120/200. i changed the sleeve that surrounds the scrubber to no avail. does this mean its run its course and i need to replace the whole system? im freakin big style.
