Hello guts I have a grow tent (80cmx80cmx180cm) with a 400W HPS Grow Light and a exhaust fan (200m3/h) my question is is the exhaust fan strong enough to suck the hot air out of the grow tent?

It may not be enough. I use a 250w and mine is a 185cfm and it just about keeps it at optimum temp. I also use a 105cfm inline fan for clean air. You may be better off with a 6" set up. If I'm correct, you can push approx 300cfm

Whats the highest temp for the plants?
Example
Extra Large (XL) BudBox Grow Tent – 1.2m length x 1.2m width x 2.0m height
Extractor fan = 125mm (5”) RVK125A1 (220m3/hour)
(220 x 0.75) x 0.85 = 140.25m3/hour
Based on this calculation, the 100mm (4”) RVK100A1 (184m3/hour) most closely matches the target requirements for the intake fan.
Just substitute your measurements into the formula and you will have your answer.
