| I have my system set for about 65 to 70 % humidity, and 55 to 60% is pretty standard for me as the fogger goes on most all day. 50 to 65% humidity is much safer than 80%. Remember that when the temperature starts to fall in the evening, the humidity is going to go way up. So, half the time the humidity is higher than your 50 to 65%, and if you are at 80% and the humidity goes higher in the evening, this will be too much. Unless you have really great air movement, I think you could expect to start losing plants to rot with very high humidity at night. Cynthia |
