Fuck it, think I'm just going to try starting off with the 32 gavitas for flower, 10 regular single ended mh with air cooled hoods for veg , get a 10 ton ac(or two 5's) for the flower/gavitas and use my 5 ton mini split for the veg. I'll just make adjustments as needed, this isn't my first rodeo lol...although it is my biggest.
Good luck. 10 tons is 120,000 BTU's and that still might be a little short of your needs if it get's pretty warm where you are
