How long do you think to get this dead standing post oak to acceptable moisture content? It was around 28-29% when I split it.

What stove is the wood going in?

The only way you’ll know is to pull a piece at the end of September, split it, and measure it.
 
I'd like to see some blowers moving the air through

Too much airflow will cool it down. I think OP has the right idea with just enough vents to let the moisture out. Personally I would've wrapped the plastic all the way down with just an inch or 2 open at the bottom.
 
The bottom couple rows have actually been seasoning for a year and the moisture was below 10% on a couple pieces I check so I wasn’t worried about them not being wrapped. I think a fan might be helpful on green wood but with this tree already being dead it wasn’t holding as much moisture. This is my second year doing a kiln so I’ll see how it goes. For some reason I didn’t cut near as much wood this winter as I usually do so I’m behind!

Yes, I think a blower would help move the humid air out of the plastic tent. If you can see water droplets on the inside of the plastic, that means the water condensed and did not come out. If you wrap it all up but install a chimney pipe roof flashing on the side you can terminate the plastic there and mount the blower. Even better would be a blower on each end. It would suck air from the bottom and move it out. Even if the blower was not running, or not there due to rain, there would still be ventilation.
 
You need to circulate that air inside not vent it out. I bet I’d measure the temperature at the center of the stack it’s much much lower.
