Top of the line for me is a aprilaire e100V , with fresh air damper kit. You can add an intake to it to bring outside air inside, in cycles per hour. If the air coming in is too humid it will turn on the dehu . I like aprilaire products alot but most growers I think prefer quest. They are more efficient when u put them as close to the ceiling as possible as well (better dehumidification when it's warmer)
These do dump a ton of heat, and a 80 pint would be even better but I'm not sure if they make that with that nice air kit.
You could also add air conditioning/heat pump to help negate the heat and give you full control. You need the dehu the most though then worry about heat, if growing under LED it can be 85 and be OK
