Ok so I have had my thermo/hygrostat going with a 40w day glo bulb and a 40w moonlight bulb (blue). My temps got up to 82 degrees for the daytime but when I switched off the day glo bulb I was only managing 73 degrees for the night time temps. I can upgrade the blue bulb to a 50w easily though. So I guess Im asking if anyone thinks that the extra 10w will be enough to bring me up to 77 degrees for the night temps? I have a uth that was constantly running for day and night. I dont have the frog yet because Im just trying to sort this night time issue out but I think I will be ready soon! #EXCITED!
