New to this guys and got 2 plants that I just put in a brand new AC Infinity 2x4x6 grow tent with everything needed. Just wanting to see what the perfect or ideal temp and humidity should be during flower. Right now I'm at 78-80F and 50-55% humidity. Just seeing what it should be at. Appreciate any info

I'd say you're good right now then. I usually don't get my VPD much lower in flower. But, if you have mold/fungus issues at all you could consider lowering that VPD a bit later in flower.

Didnt even notice my controller on the tent had VPD. It's 1.39
You need to set leaf temp offset, its under settings. With LED, leaf temp is usualy 2-4 F under air temp.

Low to mid 80's air temp is good with LED, less with HID. Many run humidity lower than ideal to be safe from bud rot in mid-late flower.

How are you guys getting humidity lower in your tent? I can't get mine to drop below 50. Usually it's around 52-54% but when lights are off 50 and temp is 73-75 when lights are off.

Dehumidifier in the room and good airflow. I've had to upgrade to a fairly large dehumidifier, like a whole home unit, to get the results I wanted.

Damn lol. Dehumidifier will def be something I'll get and I've read that another oscillating fan will help. So Im probably gonna grab both of those and hope that'll help.

If you have plans of automating your grow down the road make sure it's one that resets and comes back on automatically if the power is turned off. Some of the ones with digital switches have to be manually turned back on and won't work with temp and humidity regulators like Inkbird makes. Get one size bigger than you think you need and if you increase the size of your grow you'll be good, the bigger one can work at a reduced load until you upgrade.
