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

Genesis 1:29-God said, โ€œLook, 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. Iโ€™m no expert, Iโ€™m sure theyโ€™ll be along shortly ๐Ÿ˜€

@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 theyย  fluctuateย 

Sucking โ›ฝ

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

@dobbin hi mate,ย 

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... Iโ€™d prefer 28-30 but that will happen soon as the ambient temps warm up here in uk.. Iโ€™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 rangeย 

Iโ€™m trying to go for 2c higher than i would with hps if possibleย 

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 Iโ€™m not sure whether this is as relevantย 

hope this helps

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

ย 

Time to pop some more beans ๐Ÿ˜—

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)ย LEDย spectrums to happen to have anย idealย amount of blueย light, and aย goodย amount of yellowย lightย forย growthย power. Even though red and infrared are mostly left out, it's a decentย growthย spectrum. Go any lower to 1000K, and the blueย lightย will drop below what isย good forย plants. I would like to recommend you this <a href=" removed link " target="true">site hope this could help you have a nice day.

I know this is old would you stand by what you said back then @monkeydo dipping to 70f at night & 80f dayย 

Night/days temps variable for each grower i Know that.

i was just mulling over what the optimal temp is at night/lights of now I can actually control it atm with it being cold.

does chillbert post anymore I havenโ€™t seen him in agesย

@mix, my day/night temps change throughout the grow. My veg temps are higher and humid, night and day don't much care what it does at night during veg. Then stretch can be warm days and warm nights to slow stretch and then cool days and nights during flower, this is all in a perfect world and doesn't happen very often, only in a small space of the year for me. The rest of the time I have to put up with what I got.
