I have two ac infinity probes at each side of rent at canopy level and I get those temperatures I listed. My humidity has been about 40-50% and no higher or lower. I’ve read people using a luxe reading of 30,000 and not having any issues so I figured 12,500 is perfect. Also two fans blowing 24/7 but not directly hitting any sites.
Hi Dutch,
Nice grow! I'm still very new, on my 5th grow; but I might have a couple things for you:
Probe location - the side of the tent will not be accurate. re: more air moving along the flat walls & less radiation hitting the probe will skew the readings.
--- Hang one probe center and a few inches above the canopy - there's the hottest reading.
--- Hang the other probe center at soil level - highest rh is here.
--- I move a temp / rh meter around the tent often to tune airflow (still building out my 4x8 as I go...)
- sides of the tent, - finding dead air spots where budrot could happen
- in front of intakes (3x 6" passive ducts pulling from the outside)- I pull from outside, so I like to see what temp / rh is coming in
- on top of LED light case - surprisingly cool.
- next to the AC Infinity probe - calibration they're within a degree / % of each other.
Based on that, I run my canopy temps (lights on) from 78f - to 83f (occasional swings outside of range)
RH has been tougher for me to get a handle on, my region can have huge swings in a 24 hour period.
So far, I had budrot on my second grow, but adding clip fans cured that.
