Day 4

VPD. I'm staying on the lower end and not in the zone. Lights came back on at 4pm and after an hour I'm at 80F, 78%RH and 73F on the leaf. Most articles suggest that LED lights normally produce a 2F leaf offset. (Could be my IR thermometer as well.) Plugging these measurements in, I get 0.04 kPa which puts me into the "under transpiration" zone. So at roughly 80F, decreasing humidity looks to be the best option to increase VPD. I have a wicking rag and water bucket, so removing that I doubt will decrease it much. Humidifier has been turned off.
