A drivers or B drivers with built in potentiometer?
Have you a kilowatt meter?
I'd dimm both lights down to min , if they're A drivers and get lights closer to plants - less light wasted on the walls.
Using lux meter you need ~ 20,000 lux - 40,000 for good veg.

I Switched to 12/12
My Plan is ;
Week 1 - 25.000-30.000lux =
Week2-3 - 30.000-35.000lux=
Week3-8 - 40.000-50.000lux=
Week9-10- 40.000lux

Or after week 3, full 50.000lux till the ende?
I dont know for sure , but i think the most light
Is needed at week 3-6 right?(bud devoloping,Bildung white hairs)

Sounds ok if u wanna save on electric.
Personally, I'd use 50,000 all the way.

good question..so the chorophyl comes out of the leaves more

as for w/sq ft and closeness.

you know closeness is realtive to how many actual diodes one uses

and the wattage each diode is run at..so its never a constant thing unless all these are equal..

answer

i have alot of diodes and run at lower wattage per diode so i get within 6"

Ok i understand (just at the end)
Chlorophyl taste uuuugly


So you prefer less distance,
Does it makes a different(with strips) if your light is 1 feet 50.000lux(maybe 330watts)
Or 2 feet 50.000lux(maybe 400w)

Sweet. Just keep it that distance and move as they stretch and keep an eye on them
Iam at day12 skunks growing great(6-7inc) , nice Big stems, and Bushy.
The amnesia are Double in high(8-12inc) much more high growth (Bit stems to) ,iam Not sure how they will stretch(i am a Bit afraid that they stretch too much)

VPD is +-1.0

Glad to see its going good for you.
Oh the joys of juggling different strains..... lol
Either raise the skunks up to the level of amnesias or bend the amnesias down to even the canopy .
You've probably another couple of weeks for stretch to stop.
You're asking the wrong person re VPD, I don't bother with worrying about technicalities like that!
Keep it simple I say, correct amount of light, one bottle of feed - Tomatorite - from start to finish and good airflow works well for me :lol:

Oh, yes i cant grow just 1 strain, i need MORE ;)

The skunks is under 1 panel
And the amnesias are under the other panel ;)
So i can raise The amnesia panel higher ,
A hope they dont stretch to much(day and night temps are pretty close :)

I am Happy when i have done the first run

Short question, i have a cheep lux meter from eBay and 2 apps, when i measure with all 3 ,
The cheep lux meter is always higher than the apps when i am outside and the lux meter says 60.000lux the apps say 44.000-49.000lux

The phone app's results are limited by the quality of the light sensor in each particular phone.

I run 2300w (1100w at the wall) of LED in veg on a 20/4 cycle then flip to 2 x 600w HPS (Sun master Super) for flower at 12/12 or 13/11.

I don't want to get into a row on here but as good as LEDs are for veg I've never had decent results from them in flower.

In veg LEDs keep the plants short and stocky, but in flower the buds are small and I struggle to get 0.5/0.6 grams per watt (actual at the wall wattage)

Under HPS I regularly pull 1.0/1.2 gpw.

Just my 2 cents.

The fact that you listed two different wattages for your LED makes me think you're using blurple, yes? (Based on the old marketing gimmick of listing the potential wattage of the diodes rather than the actual wattage being drawn.) Massive difference between the flowering ability of those cheap blurples and a proper white-light LED fixture using good COBs, strips, or Quantum Boards. Most peeps around here see well north of 1g/w with modern LED lighting, with many approaching 2g/w.
