Probably get flamed for this,
Disclaimer:
I have no lab, cannot afford one or even have access to a lab. Only myself consumes my product so no need to care about anyone else's effects.
In my limited experience harvesting cannabis, plants that I left on the rootball sitting in the dark vs the ones cut from the roots and hanging right away, the ones left on the root ball took longer to dry out versus the plants cut during light. Talking total time of plant drying after each one was cut from the roots.
For this reason, when humidity is lower than optimal, I give them extra hours of dark, plus not in any hurry am just trying to get dry time slowed down some.
I do NOT have an optimized environment so have to adapt.
This is observation based.
