hey DrKing, are you re-circulating the air back into your tent? (first pic) Personally I wouldn't do that but ewveryone sets up their own way. If you are drawing hot air out of the tent, you don't want some of it being sent back into the tent (which is what it looks like - even though you have filtered the air of smell - the temperature of it will still be high). Perhaps it would be better to remove that T joint on the outside and have a passive intake at the bottom (or get a small fan for that). This may even reduce temps and allow you to run the fan lower. Just a suggestion.
Morning everyone, glad to see you are all getting into the Friday spirit. Saturday over here now
