Tents 34.3c and 21% humidity. Crazy hot and dry today. Think it got down to 18% at its lowest today.
Thats a room VPD of 4.5 and a LVPD of just over 4. Partly why I think stressing over VPD so much is trivial. I've had summers at this 3-4kPa for weeks at a time and the plants are always happy. Leaf temps still 2c lower than ambient which means transpiration and water transport from the medium is fine at those numbers despite the literature stating anything over 1.6-2 is detrimental and hard to keep cellular water pressure up.
