Nothing i do will bring my leaf temps up either. I am just assuming it reads 3.5° difference. It said it could be +/- that ammount
I have actually downloaded that lux meter on google and the numbers do change. Kind of weird that they would change if i didn't have a light meter.Well shit. That means your phone doesnt have a light sensor
Seems weird though. My s5 and s8 have it by my wife's a20 doesnt. Maybe they stopped using them?Damn! I have the s20+ too. Maybe the plus doesn't have it
How are you measuring foliage temp?Nothing i do will bring my leaf temps up either. I am just assuming it reads 3.5° difference. It said it could be +/- that ammount
Yep. 0 in the closet and up around 2500 next to the bulbHold it up to a light bulb and it should go up as you get closer and down as you get farther away. I have that exact meter too
With a $20 ir gun from home depotHow are you measuring foliage temp?
The sun was 60,000 lux earlier. And my lights are out right now. I can check at 10 pm.At 12" distance with light on max what's the reading?
Sun can be anwhere from 2k lux to 130k lux depending on time of day and cloud cover.
I found this one to be a good app.

Remember that's plus minus % so it more accurate than you think. Leaf temps are hard to change... especially under LED because the lack the IR... nor far red but IR.With a $20 ir gun from home depot
I have 1 16 inch oscillating fan inside. 4 inch ac infinity fan bringing air into the tent and a 6 inch ac infinity fan sucking air out of my bedroom window at the same time. Can i shut aomething off to decrease a little bit of the airflow to bring them up?Remember that's plus minus % so it more accurate than you think.

The easiest way is increase the room temps. Keep good air circulation through the plants but not direct airflow. You'd be surprised how much evaporative cooling affects them. Then another big factor is the root temps so keep pots off the floor is important as that can lower root temps and in turn plant and leaf tenls quite a bit also.
And then my res is under my flood table and my nutes will get too warm. I am fixing that next grow. I am going to build a platform to put my tent on and put my res directly below the platform outside the tent. Warm water problem solved. It stays a constant 69 or 70 degrees in our house.

Don't worry about you tent temps... as long as the leaf temps are good your golden.Ok. Yes. I need them lower. So i have my light at 60% and it keeps it a steady tenp of 80 when i have a negative air exchange. No flaps on the tent open. I have been worried about the temp being to high when i turn my light up for flower. My leaf temps are staying around 7-8°f lower than the temp in the tent
Ok. So should i turn the percentage up on my light? Or move the light closer to the plants to increase leaf temp? I just put new water in my res. And its cold. But it should adjust by tomorrow. Before i changed it though it was around 74 or 75°. But they started doing really good with those temps. Then my res got all out of whack. They were using nutes because my PPM started to go down. Even after 3 weeksDon't worry about you tent temps... as long as the leaf temps are good your golden.
