Air is locked (called enviormental roll ) in the tent = no Neg pressure, System not ducted correctly , the fan that is supplying the fresh air ,just let it supply in the room it self (remove intake to tent) Now what you have created is a positive presure room , Now I would need to know the CFM of the fan that is exhausting from the tent to really help but here is a base line on what is needed to correct your air flow , if is 200cfm you need to use or create a 8'' round opening in the tent, if the exhaust fan is 201- 500 cfm this opening would need to be 10'' round,then you will have crated a negtive pressure enviorment in the tent, if you follow my instuctions you will achieve close to a 1 min 100% air exchange ,and your tent temps will be with in a 2 deg dif from your positive presure room temp. I move Air for a living 30 + yrs exp.

...this is why searching for knowledge is always faster and usually better than waiting for it.

anyway, CFM = Cubic Feet per Minute and to calculate it you need to measure the inside dimensions of your growspace, how deep, how wide AND how tall, then multiply those numbers, depth x width x height to get your CFM, or how many cubic feet of air space contained within your grow. (hint, hint, if you do a google there is an online calculator that allows you to just input your numbers)

...the fact that you still don't know something this basic shows how little effort you have put into learning this skill, ...and it IS a skill grasshopper so if you don't put any effort in, don't expect to get much back.

it takes more than just popping a seed and hoping for the best.

peace, bozo

You dont really have many options. Since you cant keep it cool with the ambient air you will have to add cooling. Portable AC or get a smaller Hid bulb.
