So I should buy what size air intake . I’ve grown for the first time in 2020 but the environment was to hot

I’d suggest starting off much smaller and work your way up to a room that size. I usually passive intake on my tents so I just open the flaps. The negative pressure from the exhaust fan pulls in fresh air from outside.

You really should read the link I posted. There are multiple variables when calculating the size fan you will need. With a 11’x11’x11’ room that’s 1331 cubic feet of space. A baseline exhaust fan you would need is one that was rated for 1331 CFM. Plus you have to adjust your needs based on carbon filters, duct length, duct bends, etc.

If I had 11 foot ceilings I wouldn’t grow anything but sativas
