Air Conditioner Ideas

I have recently made some switches in my room to avoid the crazy heat issues that this summer has brought. My old setup inlcuded:
1000 watts, wide open with lg in-room air conditioner+ 2 oscillating fans. = 95 degrees at the hottest point in the day. This is in the bloom room, but air is pumped into the veg room with 1 600w closed hood; this room is also at 95 degrees

new setup
600 watts, enclosed/air cooled hood, lg in-room+2 oscillating fans = 85 degrees at the hottest point in the day

I want 78 degrees. I was wondering what air conditioning units would be good to cool both rooms. I would like to purchase just one unit to cool both rooms, but am still not real experienced in the air conditioning department.

i should also mention that i plan on having the bloom eventually be 4x 600w enclosed

At are store we have a 24,000btu Mini-split AC/dehumidifer/ heater for $1650. They make smaller and bigger units and multi head. The most efficient way to maintain any temp you want.

Ductless minis are nice.

Make sure the model you choose will auto resume operation after a power outage.

Low ambient models will run when it's colder outside, should this be an issue (sealed co2).

You get what you pay for (hint). Mitsubishi is the cream of the crop. Sanyo compressors are good too.
