I will do that. It was at about 600 this morning.
The intake for my room is from another room upstairs. Anything I could do to improve on the air in the room where it draws from? For example, I could open the window in that room for outside air (too cold right now) or I can heat or cool that room to control the temp of the intake air. Or, I could do a sugar and yeast thing and set it near the intake (not sure that method is very effective, though).
However, I do have options in that room in regard to temp, humidity, etc. Kind of nice because I can run (a humidifier for example) and not have to have it take up space in my grow room.
