Have a 5x5 flower tent going and a 10x5. The 5x5 is usually around 71-74* and 62-64 RH during lights on climbing to 69 RH lights off. I think I’m ok here.
My 10x5 runs 81-82* and about 55 RH during lights on…. Is that temp going to give me issues? I can’t seem to take it down much. I toss the home AC on during lights on but it’s still high
Running two 1000w spider farms. I was at 80% on each light just moved to 65% temps down to 79. Not sure what that will do to bid quality or yield though
Nope ones almost touching, they’re at tent ceiling (even moved scrubber to floor) and one plants 5” from light . Can’t lower them AtlesSt on one side. Maybe the other side a bit
10” AC Infinity T8 exhausting, 6 tents fans, and the far side of tent open sucking in dehumidified fresh air. Currently now I got it to 79* dimming those lights a bit from 80% to 65ish
80-82f is fine. Since you’re using LED’s that don’t put out infrared like HID lights your leaf surface temp is likely going to be lower than the air temp by a few degrees if you have decent airflow.
Yeah the amount of IR LEDs put out is much less than HPS lights. LEDs also tend to move their heat upwards into a heat sink and then up above the canopy where HPS would direct it down towards the canopy and carry more radiant heat That’s why they have to be mounted so much farther away from the plants vs like 1 ft.
I would def not want a run a HPS room with an air temp of 82 because the leaf surface temp would likely be higher than the air temp. With LED it’s fine (or even ideal) at that temp range because at 82-83f air temp the leaf surface temp might be 79-80. It doesn’t heat up the leaf surface as much as HPS.
IMO leaf surface temp is a better metric than air temp for figuring out vpd for the grow room / dialing in the environment. Most people use an IR thermometer but if you have more money a FLIR camera would prob be even better.
