Hydrofarm - Active Aqua HGCH1/10 Active Aqua Chiller, refrigeration unit 1/10 HP
heres the link to tha lil guy.after speaking with the hydro store, it sounds like it may defective,or my room at 90deg F is too hot...but i would expect more than 3 deg of cooldown even at room temp of 90, b/c my rez temp would still only be up at 82 at most anyway. if you are having rez temp issues w/ root rot,try using some beneficial microbes...ive been rockin the aero60 for 2yrs..w/o a chiller.and yes 2 liters are whatcha gotta do in the summer in cali if ya dont have a chiller.
