Mike was (is?) the owner of Mandala Seeds.
I used a digital thermometer with an attachable probe to detect "outside" temps, bought from Walmart. I fixed the probe to the reflector so that it was dangling down right at canopy level (which I adjusted as the plants grew), and then I used the "outside" button on the thermometer to measure the temps of the inside of the tent. It also saved the high and low for each 24 hour period, so that was cool. I could see how hot or cold it got when I wasn't around.
Yes, all things being setup properly and tuned in, you can keep the temperature in the tent right at or within 2 degrees of the ambient temperature in the room.
Remember, just because you are feeling air blowing out of the tent doesn't mean that the airflow is being channeled all the way through the tent as it should be. If you have a way of zipping the tent up so that the part that's open is down by the floor that ought to help, I suppose. That intake port you described sounds like it's a screened window instead of a ducting port. What brand tent are you using? I thought all of the brands used ducting ports with drawstrings. Anyway, all you need is for the intake hole to be about twice the area of the exhaust hole. If the tent is imploding from too much negative pressure, you can dial the fan down with a controller, or you can increase the size (or number) of intake holes.
