I was just making a little joke there. I run 80 to 85f, 70 to 75% with anywhere between 1000 and 1200ppm co2 in veg through the second week of flowering then start to reduce temp humidity and co2. by fourth week running 72 to 75 degrees about 50% humidity and around 600 ppm co2. I grew indoors for quite a few years before the internet came around and never even heard of vpd until I started lurking on the farm back in 08. I think that you would have to be pretty far out of wack for vpd to really come into play. Plants will grow happy and healthy in a pretty big range of temps and humidity.
