Anyone know what leaf offset AC Infinity uses for the 69 pro controller VPD?

Please and thank you

The answer is one can adjust it in settings

I think I read the offset is 0 from the factory.
But it is a personal number, you need to collect the data points from your setup to determine offset

Congrats on the C69! It's a very important part of my grow environment.

Leaf surface temperature offset varies. For most of my grows, it's been -2°F from ambient. For my last grow, I set fans up so that the canopy was getting 2 meters/second of wind and LST offset was -5°F.

I measured wind speed using a Uni-T anemometer ($25±). It's something that won't be used very often but I bought it because wind speed is an one of the 10 parameters of a grow environment so I figured $25 to make that aspect of my grow "perfect" was well worth it.

Default is 0 depending what you have led or hps you would go to a positive or a negative number led is negative.
But each user has different living enviorment.you need a heat gun to know exact number

No point in chasing perfection.whole vpd system works with outside temps and only setting you have is manually saying its lower or higher.you cant attach a sensor

As a guy whose grown outdoors it seems like the whole VPD thing is a bit overblown. Still, I'd like to be as dialed in as possible and I can justify the 25 clams between the tent and my pizza oven.

Vpd is a cool thing just ac infinity auto vpd is shit

it's great for turning a fan on or off, if that cures ones ails I suppose.
