Honestly,I want to grow.
So whatever is the cheapest. I can leave the veg side open ,that's no problem.
So I guess I really need to be concerned with the bloom side. That way it can stay closed off from the rest of the shed.

Ok, hmm. I suppose my area is continually exhausted (2-600's) around 2-300 cfm (used to be air cooled, til gavitas). Then a 9k btu ductless is plenty to keep the veg and flower at 73f. Lose a bit of cooled air out the hoods; but it exhausts most of the high heat w/o cooling. (just as a for instance I guess lol).

I'd be hesitant to try and cool a 4x4 space directly with an A/C unit (since not ductless). As the cycle time for the compressor will limit your control-ability some (5 min off period). Though if you cooled another air volume like the whole shed, then cycle times would be less of a thing on the 4x4 space.

Guess I did have a thought after seeing the suggestion and response to run dual exhausts. So, possibly cool the whole shed (or an another volume separate from 4x4 flower) and have exhaust for each 4x4 space. Presumably this is currently where your at.
As a thought (for flower), you could use a dimmer to reduce your exhaust speed to just eliminate hood heat (so, 100 cfm or so, I.e. 25% fan speed). Then your temperature controller can separately bypass the dimmer when triggered to speed the fan to full exhaust rate (so, 3-400 cfm). Cool air from the main shed can just be drawn in. Suppose you could do the same for both rooms separately (2 dimmers, 2 temp control, 2 exhaust fans). That should allow for decent control of each room with only one AC in main shed.

Wiring would be something like this.
2 speed exhaust
