VPD transitioning going into flower
What’s everyones VPD sched or transitions going from veg to flower? Or should i just say throughout the grow?
I’ve always popped seeds at like between 5 and 8.
I go from about 8 to slightly over 1 during veg.
Stretch I try not to go higher than 1.3 usually staying at around 1.1 to 1.2.
After stretch i usually start around 1.3 and finish flower at 1.5
What does DGC do?

im pretty well aligned with what you posted… around .8-1 for veg, aim for 1 during the stretch. from there slowly raising VPD through flower and finishing at 1.5 for the last 2 weeks, which is a tiny bit higher than most folks finish… BUT by finishing nearly as cool and dry as my grow can muster (73f, 40%, with -2 degree leaf temp) The low humidity really helps in preventing botrytis IMO and im not worried about growth rates those last couple weeks.
I personally dont mind the hastened senescence and a little bit of crispy tips. I also go back to generative irrigation strategies those last 2 weeks. i feel this can cut down on guttation to help prevent mold, as well as gently guide them to finish and bring out that color.
Here’s a nice clean crop nearing the finish line grown under those parameters. Glubricant ((agvxgg4) Apple fritter) (by me), MAC, and Chillz (by Cap) pictured.

Right on! Yea im not worried about leaves too much in the last couple of weeks. I’m usually going like 70 days in flower every grow. Senescence and calyx swell is my favorite time of flower. Watching a flower truley ripen never gets old. Beautiful grow!
