Is it worth it to seal my grow and add co2?

Hi! I have some questions I could really use some input on...

1.) Is it worth it to seal my setup and add co2? I am heavily leaning this way.
2.) Do I need any additional equipment other than a co2 tank, regulator, and co2 controller?
3.) How does the ventilation work in a sealed setup? Do I just run my flower room exhaust into my veg room and eliminate my passive intake?

I am using a 16'x20' insulated shed (grainery) in Michigan to house my veg and flower rooms and I feel like I am throwing a lot of heating (in the winter) and cooling (in the summer) right out the window! $400-$600 a month in electric bills alone! This seems excessive to me for such a small setup.

Here's a brief rundown of my current setup....

I have a 16'x10' room partitioned off for the flower room, a 8'x10' area partitioned off for my veg room, and another 8'x10' room partitioned off as my "work" room which is where my ballasts are hung and which has passive air intake from outside through screened vents.

Flower Room:
3x 600 Watt HPS Bulbs, ballasts mounted in the work room, in cool tubes that pull cooler air from the veg room and exhaust it outside via 250cfm inline fan.
The flower room is exhausted outside via a 450cfm inline fan that pulls room air from flower through my carbon filter.
5000BTU Window Air Conditioner and 1500 Watt electric heater on temp controls to maintain proper temps.
Dehumidifier hooked up to external drainage.
2 Oscillating fans, wall mounted.

Veg Room:
2x400 Watt MH Bulbs, ballasts mounted in work room, batwing reflectors.
Oscillating fan, wall mounted.
Passive intake from work room, passive exhaust to flower room, air exchange is created by the exhaust fan in the flower room.
5000BTU WindowAir Conditioner and 1500 Watt electric heater on temp controls to maintain proper temps.

The flower room is airtight, I could make the veg room airtight fairly easily... but I am not sure what I would have to change ventilation wise or if I would need any additional equipment outside of a Co2 canister, regulator, and Co2 controller?

I am thinking I should eliminate the passive intake in my veg room, re-route my flower room exhaust to my veg room, re-route my cooltube vents so they pull air from outside instead of from my veg room, and seal any air leaks, add a tank with a regulator hooked up to a co2 controller.... Am I missing anything?

Any input would be greatly appreciated, thanks!!

i have no clue :) but u want any Input?

I feel like I am throwing a lot of heating (in the winter) and cooling (in the summer) right out the window
maybe some sort of exhaust gas heat exchanger would help

Am I missing anything
maybe a gas concentration toxicty level sensor/alarm
