I have a TSW 2000 in a 3 x 3 tent. Any ideas on leaf temperature delta, if ambient air temp is 78F, 61RH, 20in above canopy and 1000 ppm co2 +/- 150 ppm supplemented. Figuring out VPD. It varies greatly if leaf temp delta is 2, 3, 0r 4. My IR gage for leaf temp says @ 76F with oscillating fan. Any Ideas or direction pointers?
What’s the question? Seems like you’ve already measured it at 2F…
Have you tried this…
