Thanks
@kratos015 ! I checked out the link you posted, does it do regular environmental controls as well or co2 only?
Also wondering if I can ask a local welding shop to fill this o2 tank up with Co2 or at least swap out for a co2 tank? Take a peek...

Unfortunately, it does not to regular environmental controls. If you want an all-in-one controller that's going to set you back $500+ unless things have changed. What is it you're trying to control exactly? Humidity and temps I'm guessing?

That'll control your temps, whether heating or cooling. It's good enough for people that brew beer and age meat at home so it's certainly good enough for me! Plug your inline fan/evap cooler (if you're in the right climate) in and you're set. If you're using A/C, the thermostat on the A/C will do the job just fine. IMO, you don't need to spend money on a controller for a heater/air conditioner because any heater/AC unit worth it's salt will have a thermostat that will do that for you.
The only thing that leaves left to control is the humidity. Humidifiers with built-in humidistats are cheap enough, I got one for $50 that was plenty good enough for a 4x8 tent. De-humidifiers with humidistats are a tad more costly, $80-$100.
Not sure how large your grow is or if you're even running more than one light at a time, but if you are this is the light controller I use.

30A @ 120v will run 4 600w lights, 1 1000w and 3 600w lights, 4 315w CMH, or 3 1000w lights. You don't even have to wire it into a breaker, assuming you know enough about wiring to not start a fire of course! I have an RV pedestal on my property that I'm using to power my light controller. Just cut the female end of an RV cable off, stripped the wires and wired it into the controller and it works just fine for me. You could do the exact same thing with a dryer outlet as well.
I've had all of the aforementioned equipment for the last 2 years, zero issues and I still use them all to this day.
As for your CO2 tank, unfortunately I can't help with where to fill that up as I use a propane CO2 generator I bought on eBay that has worked just fine in the last 2 years. A propane generator will heat up your grow space, but only while it's on and if your CO2 generator is on constantly then you likely have too small of a generator for your space. I like propane for CO2 because it's more user friendly in terms of plug and play, but the main reason I like propane is because no one bats an eye when I'm refilling a couple of propane tanks every month. Sadly I can't say the same about a tank.
