Using the formula I presented the math is correct. (disclaimer not all strains will have the same flowering growth spurt)tent =80
ground to bottom of cool tube 62 inches
pot. is 9.5 inches
I'm going to go with 12 inch safe distance I have a cool tube and a 430 cfm exhaust
ok plant can be 40.5 inches tall so around 18 to 20 inch I will flip sound good?
A tip on how to find a safe distance from your light. Put your hand, palm down about 6 inches below the light. Hold it there for roughly 30 to 60 seconds if it doesn't feel like you're getting sun burned it's a safe distance. If it feels like it's burning, go lower until you find that butter zone.
