Airflow methods while drying in a tent

I have a tent with a cheapo vivosun 4" inline exhaust fan piped outside and vents at the bottom on each sidewall, and have fans. I also have a second inline fan that I can use to.force air in or out if I want to create positive or negative pressure.

Which is better way of providing airflow while drying in my tent with the options I have?

A. Use a fan to blow air under the plants with the exhaust on and intakes closed to create negative pressure?

B. Use a fan to blow air under the plants with 2 exhaust fans on and intakes open to exchange more air, no pressure

C. Use a fan to blow air under the plants with the exhaust off, intake fan on, and vents closed a bit to create positive pressure?

D. Use NO fans at all, and just use the exhaust systems to pull in fresh air equally at the bottom with all four lower vents open?

E. The one that will best keep temp/humidity in check in your tent.

Lol, good one. I do have two dehumidifiers, on in the tent and one in the room. I'm gonna shoot for 65⁰F to 70⁰F, and RH 50% to 60%.

During the last two weeks of flowering till now, I have been having temperatures between 65⁰F and 72⁰F, and an RH between 39% and 45%, except when I flush it rises to 50%, and when I spray lost coast for PM control, it gets to be 70 to 80% for a few hours till it dries back to 45%.

All through the flowering stage, I've tried to keep the environment VDP between 1.2, to 1.5kPa
