opie I run my AC set at 78 deg during the light on time and then when lights are of it is at 73 deg....I was told that they like that cooler temp at "night" that is why I have it set up like it is, that way it is ALWAYS consistent. reguardless of the temp outside the room...

yea,I've not heard the cooler temp = the color change before, but I have heard that the cooler temp will change the "tightness" of the bud...or something like that...
