Which temp do you go by during flowering, is it room temp or is it canopy temp? Im hitting 91-95 right at canopy but the room is 78-82 are these number to high during flowering I am ducting in and out, oscillating fan is running
I measure at the canopy. that's where the action is. keep that at 80 during the day and 70 at night room temp is a consideration as reservoir is in there too. and i monitor the temp in the room 1' off the floor fan speed increases if temp at ceiling height gets above 80, that's measured at 6" from the ceiling during flowering temps should stay under 80 ideally and 60% and under humidity is ideal cheers
An infrared "gun" thermometer can be used to figure this out. My leaf temp is 7 F lower than air temp, and that's what I use to determine Vapor Pressure Deficit. I've seen posts about 5 F lower. Very likely those old school recommendations about temp are based on air temp, not leaf temp.
root temp affects nutrient uptake, canopy temps affects leaves and buds. Ambient especially over the lights affects the lights. Most leds risk damage above 90, not sure about hid operating limits if any. 78 to 82 is my ideal range for everything all the time, emphasis on the My.
I don't see how you can go wrong with those temps Agree. Good Temps. I don't see how anyone can go wrong with those temps..Regardless of light source.
