If you have LED light, you definately should increase the light level to 400 ppfd! 150 is much to low.

150μmol/m².s is very low to me.
You can start increasing gradually to reach 400μmol/m².s

Looking at your pics I'd say the light height is decent where your at.

What are you checking with? How does the plant look? What's the light manufacturers recommendation?

LUX meter grow questionCan someone check out the LUX meter video and tell me how I should be positioning my lights? I think maybe I have too much light on them.
My meter says 600 (x100) that puts me at like 60000 lumen. The converter I used put that to 1541.36 umol/s/m2 which is a lot of light alreadyWeek 7

Kind LED XL600 series 2 heights?Hey,
I’m running 2x Kind Led xL600 series 2 lights and seen people running much much lower hanging heights than recommended (18inch instead of 30inch) and wondered if anyone has any PPFD or PAR readings at anything lower than 30inch or any reasons why they run them lower.
