I WAS TOLD SHORTLY AFTERWARDS THAT IT COULD CAUSE TOO MUCH HUMIDITY & CAUSE MOLD! I HAVE 7 NICE SIZE HOUSE PLANTS IN THE SAME ROOM. I ALSO HAVE 3 CHIHUAHUAS & A CAT THAT CAN REACH IT TO DRINK, I ADD FRESH WATER IN IT EVERYDAY & IT HAS A NICE SIZE PUMP IN IT SO IT TURNS THE WATER GOOD. WHAT ABOUT THE HUMIDITY???
