Im definitely a believer in vpd for veg and mid flower. However i find i like to ratchet the rh way down low as i can get it near the end. Thats putting me north of 2.0 on the vpd monitor.
The charts ive seen seem to call anything over 1.6 the danger zone.
Anyone else with this mindset or am i out on a limb?

I deffinately follow a VPD chart as close as possible from propergating through to late flower but dont go down too low while they’re still drinking, we’re only preventing bud rot aye?

I’ve never once in my time growing calculated or figured out my VPD, it could be off charts for all I know lol. I don’t know, my plants never seem to care. Like yourself I flip the dehumidifier on as needed in late flower.
