Set up an evaporative cooler to act as an intake and to cool the temp through evaporation. It I was able to get the average temperature down to an average of 77°. Relative Humidity increased to an average of 55%. ~~~~~~~~~~~~~~~~~~~~~~ Evaporative Cooler: The evaporative cooler was way bigger than I thought and blowing all the air into the tent would be overkill and would throw off my ventilation given that I only have a 4inch exhaust fan blowing air out. So I had to rig an air duct onto the front to channel some, but not all, of the air coming from the evaporative cooler. I cut a hole in a plastic brownie box and zip tied right angle plate that I had leftover from an ikea furniture. Then I put velcro tape to easily attach and remove the air duct from the cooler for future maintentance and cleaning. I left the room where my tent is closed one day and the humidity went up to 84% which also increased the temperature to 90° but I found that simply leaving the room door open gives the cooler enough air circulation in order to function properly and averaged out at 55% RH and 77° F. ~~~~~~~~~~~~~~~~~~~~~~ Defoliated some ugly fan leaves that were shading a lot of lower buds.
