That's cool. Thanks Redrobbo! I'll try to keep it at 80 to 85 from now on.
I went home yesterday and found out my tent was at 90 and I got so scared. I took me a while to get it back down to 84. Thanks God It didn't burn everything down.

my House Ac is not constantly blowing cool air but just when the house got hot so it blows. That's why the room is always hotter than any other rooms in the while house. I think I need a portable ac with some auto switch to keep thing under control automatically somehow.
