I moved mine outdoors for early and afternoon full sun, shade later till dark, then back inside for 24/0 for about 6 weeks, then moved to full sun only. I really prefer the full sun as they stretch less but strain, and horticultural practices are very much a part of the equation. I have a very heat hardy strain and keep stepping up the pots and next they go into the ground.
my tent always around 83-85 every since ive been growing and never had a negative affect other that bud rot late in flower so like stated earlier keep alot of air moving. but since them i rearranged my fans to keep every inch of every leaf moving at all times.
That's because your humidity is high to match the temp therefor the VPD is probably in the green zone. Everyone's grow room is going to be different based off environment.
