Was wondering what temperature is best for growing under an LED light

Genesis 1:29-God said, “Look, I have given you all the plants that have grain for seeds and all the trees whose fruits have seeds in them. They will be food for you.

24-27 seems to be where most people are at. I’m no expert, I’m sure they’ll be along shortly 😀

@dobbin We all differ , I aim for 20c dark , 25c lights on , it can dip a degree or so either end depending on the outside temperatures as they  fluctuate 

Sucking ⛽

I’m at about 21c (70f) lights off and 27 (80f) lights on plus or minus a degree or so

@dobbin hi mate, 

Depends how much light it emits imo

Eg 800umols is sufficient for maximum growth but over this and 1000umols up I believe you will need higher temps than usual plus higher levels of nutrition and co2 to now maximise as well as balance plant needs.w

Atm my room is a little on the cold side at 25-27c with lights on... I’d prefer 28-30 but that will happen soon as the ambient temps warm up here in uk.. I’m running the migro arrays 240w x 2 which is about 1200 umols/sec I believe which falls into this category ..

a 10 degree difference from the lights off temp remains ideal range 

I’m trying to go for 2c higher than i would with hps if possible 

This is only what I have heard sifting through what some US growers are doing with the latest Leds from select utube content btw

if running a small led in a small tent then I’m not sure whether this is as relevant 

hope this helps

sources and good info from FCP / mycheaphomegrow/ migro lighting / dr coco / the led gardener 

 

Time to pop some more beans 😗

I go as high as 27-28 during lights on. I see much better results when I go higher then lower on temps. Especially if I am growing sativa phenos

3000K/4000K (warm) LED spectrums to happen to have an ideal amount of blue light, and a good amount of yellow light for growth power. Even though red and infrared are mostly left out, it's a decent growth spectrum. Go any lower to 1000K, and the blue light will drop below what is good for plants. I would like to recommend you this <a href=" removed link " target="true">site hope this could help you have a nice day.
