Hello friends, puff noob here, but very sincere. I would like to ask your excellent opinion on getting the 400/500 "foot locker" humi (you all know the one) sporting the hydra SM humidifier (is it a good model, better than oasis?), I was also going to opt for a pair of extra fans to put (where, high low, opposing walls?). Overkill / just right? Yay nay? Expand. Thanks.
