yup, thats a 5500 btu. It can get that hot. What it really does is allow me to dial in my enviro. Good weed likes a good environment.

My cabinet is also outdoors in a shed. so in the summer it can get hot.. but plants stay at a cool 75/80 all the time. The winter is what is kickin my ass... LOL got down to 40 a few times. Plants still grow though.
