CO2 for I-502 Grow?

Most of our ducks are in order, but we will be using a closed system, something I'm not too familiar with.

We're using the closed system because I have had very frustrating experiences fighting high-humidity conditions.

We are looking at spaces which are potentially 4,000/+ square feet, with 15'+ ceilings. Would CO2 generators be preferable to tanks in this case? I won't immediately be taking the leap to a CO2-rich environment but, to start, will just be enriching the air to standard atmospheric levels.

you will need CO2 generators for such a scale grow. they produce heat so you will need much A/C. have you considered dehumidiers? using them you can surely control enviroment in ventilated rooms, skipping CO2 altogether. You cannot take a 1/2 leap into CO2 enrichment. if you want to do it, you need the whole system of automatic control with regulators and sensors so if you want to raise it only to atmospheric levels, you might just go ahead and raise it to optimal levels of 1400ppm. at high levels, plants will tolerate heat much better, actually they will require more heat to grow faster but i imagine the costs will be high, cant give an estimate at all...

I agree with Zem, good advice. As to costs, you would definitely need a large commercial dehummer for that space. A quick search suggests in the $5-7000 range.
I think it would be cheaper to seal the rooms and generate co2, on start up costs anyway. Cooling costs would definitely be much higher but increases in yield would offset most of that. Do some research on liquid cooling. Chillers pushing cold water through heat exchangers are much more efficient than split ac units. Equipment cost are slightly higher but the energy savings compared to ac units is significant.
