hey guys, i jus got my first co2 controller and ineed some help. ok, the unit is the sentinel chhc-4 enviramental controller and the problem is..... the unit works perfectly fine out doors all around. but when i bring it in the house, in my grow room or not, the co2 ppm's go to like 1900 or higher, and the temp reads like 10 degrees lower than what it really is. so i was thinking I must have sumn wrong. maybe i need a fan blowing directly on it? any help would be great!!! i cant start flowering till i get this right:cry: please help!!! thanks guys
