If you understand your heat product and therefore your cooling requirements you have the basics. BTU (British thermal units) converts to tons of AC as the following equation.
12,000 BTU's equals 1 ton of Air Conditioning. Being in a basement the heat lead generated by outside influences is going to be at a minimum. I would probably go with a factor of like 1.1. to 1.2. Meaning that if your total heat load is say 100,000 BTU's I would look at cooling for say 110,000 BTU's or 120,000 B

Yes but the actual design of my ventilation and how it relates to my Home AC vs Grow room AC vs Cool Tube air flow...from where to where during which seasons. That is given some of the extra advantages that I'm looking for if possible... is way more than understanding BTUS. The V in HVAC? Ventilation right?
What you're saying is in line with the 20 percent headroom that I've read suggested.
One of my questions was... for really rough numbers...if I need (for lights only) 4000BTUs for every 1000w bulb. (I believe that is for non air cooled and closer to the engineering basic of 3.4ish for air cooled) then x that by 8. I will only run 8 at a time.... so that's all I need the cooling btus for. Which is why I wondered if I could cool via a third room that I could direct back and forth. Otherwise If I could get the outside unit to handle say 36000 btus and put two 18k units inside the rooms that would be more than enough but even more expensive then it needs to be. More expensive than one each. I know that there is such thing as too much but in very big rooms I've seen it done like this to drop cold air down from the sides and help displace the hot air upwards. However in those rooms the center of the ceiling was the intake for the heat. Those are just very rough numbers for conversation and only consider the lights themselves. I'm still considering the co2 enrichment options while understanding that co2 generation produces alot of heat. I'm not sure what costs more cooling co2 heat or buying co2 for refillable tanks.
I do appreciate the advice.
We have a mechanism here in Canada for going from legal medicinal licenses to micro grow production sites. It is an option in the near future but expensive.
