Depends on the stage.
light stress can look like a lot of other things and leave the grower scratching his head .

i guess, but.... lumens are a measurement of how much light energy a light source emits. this measurement is based around the wavelengths of the human eye, and NOT the PAR wavelengths... great for measuring light used in flashlights, but not LED grow lights. :O
i wont bring it up again, though. lol

all good man I get it nothing wrong with bring technical, I was just trying to get op to realize he was blasting his plants with 2-3x the light they needed atm. I totallly understand there is a lot more to calculating a fixtures output than taking lux readings. just didn't want to overwhelm him with details when he is still learning the ropes.

Hey reggae. Can u share the formula u used to see how much lux or watt per sq foot so I can use it if need be

And also to u think it Wud Ben more efficient to have 1 of my lights going at 100 % or 2 at 50 % like is now Efficient be the word of the day here. Lol. Thanks again

I don’t know what all that means Iam a newbie. What’s the K ? 1000? And what’s Modes ? SOrry for all rookie questions But I may order the dr meter lux meter

Nope. It took years to gain the knowledge. I can't convey it all. Most of it is green thumb.

@Beehive answered it already. that is a good guideline to follow. but like he said you just gotta take time and learn some of this only comes from trial and error. different strains respond differently too. dont stress it tho. just use his numbers as a baseline.
and K just means thousand.
so 20,000 and 20K lux mean the same thing.
not to be confused with color temp K. such as 3000K, 4000K etc. that stands for Kelvin which is a temperature measurement which results in different light wavelengths.
but for our purposes here, K means thousand.

here's a rewrite maybe easier to understand
Seedlings/clones
13,500 lux at soil level
Veg - by week 2 (@ 6" or 4-5 nodes tall)
16-17,000 lux
Veg - @ week 4 (@12" or 8-10 nodes tall)
24,000 lux
Flower
35,000 to 60,000 lux
start at 35k increase a little every few days until week 3 of flower when stretch has finished at which point u can be at max.
all of this rough guidelines. listen to the plants to determine actual numbers

the orange one is newer i think but I went for the black one anyway to save a few $ and bc I didn't think I needed a detachable head.

WHen I clicked on the orange one it showed me the black one and said that’s the newer model.
