Temp issue?

I have two 5x5x6'7" tents 1k Watt raptor 6" enclosed hoods with a 10k btu ac in each. The hoods are ran in line to each other with 6" ducting into a 8" inline fan sucking out. I can't get rooms to stay at 78° any tips would be helpful

How are you venting the acs

They are vented out one of the holes in bottom of tent into the same room they are in... should i add fans to tents

Thats y its hot the outside air is hot u gotta vent those bad boys outside because they put off heat in the exhaust.. cant get the tent temp down if the heat around it is is hot

I vented the ac into my chimney and rooms are a steady 73° appreciate the help and so do the ladies haha

Ive been thinking of adding ac too. My temps are routinely 84 and up i be tellin myself the plants are fine if they are hot as long as i water them, what are the advantages of having your plants temp at 73 or so steady? Also whats you guys humidity

I really can't tell you why I just know that's like a rule of thumb 75° is what I am aiming for and humidity I was told around 53%
