you should do a side by side (led vs hps) with 2 clones from same mother. otherwise, it's pure speculation on your part.
HPS vs. LED Grow Lights — Which is Better for Growing Weed?

I like you man, you are on point indeed
But unfortunately flashlights and low intensity lights wont grow good trichomes, its a fact, not fiction.
Dont believe me ? go to the grow journals, again, check out the 90W UFO buds, check out 600w+ panels buds, check out the 400w led buds, tell me what do you think, i agree that genetics and grower play a huge role, mainly in VEG and ways to over yield plants, the trichome production is not so user adjusted but more light and water\food adjusted before hand
Btw, cfl are stronger lights then LED, hence why you saw them laden with trichomes

you just lost all credibility. and you didn't have any to spare.
What does this testing tell us beside what we already know ? 650w total panel with many many low intensity diodes that put on avg par of 1780, cool, now lets try the same testing with a 600w hps at the same height, wanna guess the par numbers ?
You still dont accept the fact the the diode itself puts out 300 Lm, a plant can use most of this 300 Lm spectrum (as your par testing suggests) but its too weak to get to your plants at the first place !
its not personal, just ACTUAL light math.

All I'm saying are my results to which I've posted pics as my proof. Led grows better trichome laden plants vs hps for me. It just does the job alot better. Hps has never impressed me. CMH has & LED has.
This year is my first year experimenting with emerson effect & T5 uva/uvb supplementation- currently in the 3rd week of flower. I still have my hps packed up in a box - retired due to being outdated compared to my other lights. I don't miss it a bit.
But hey different strokes for different folks. If you like hps that's awesome, I don't.. it just doesn't do it for me anymore.

Its closer to crayons on an Applebees napkin to be honest.
You just dont seem to get it lol
LED HAS ONLY 2-5W DIODES !!! THAT PUTS OUT 300 Lm !!!
a friggin CFL bulb (mostly never come in 2-5 watt) but instead in 14w + are stronger ! a 14 watt cfl puts out more Lm then a 5w diode
More watt indeed, but we dont have a 14w diode to compare ! so dont compare high intensity wattage lights to low !
Cant compare them, will never work, if you know your science you know this when u are in 3rd grade

I am OK, but have a couple of procedures one Monday then about two weeks later the other.
Sent you a message, but I just lost 6 Auto's in four days.
I know you don't do coco anymore, are you doing DWC or RDWC?

Except that photons are additive, which your math doesn't represent. A 600w HPS will have lower numbers, because much of it's energy is lost to non visible waves, which are outside of the PAR range.
Respect for trying different things and learning, always good to hear other people opinions and experiments.
Btw

i did grow both, im in the end of my LED grow right now.
You guys act like i hate LEDs lol... i dont, i use them for VEG and they are very good in that aspect
But, grow journals here and my own growing with them shows me that you should never flower with them
If u had good results, that only means you can have even better using a stronger light source, if u can manage the heat that is

watts has nothing to do with light efficiency. a 600w hps is more efficient at producing light than a 1000w hps..

I've grown the same strains under multiple lighting sources, and the quality is generally the same.
You are right, but only on paper, as reality shows us otherwise, i rather to stick to reality.
Because of that, to each his own, its not a fight anyway just a discussion about lights.
Sorry that i have to say this a 1000 times, im not talking about efficiency of light !
Im talking about efficacy of 1 light source opposed to 300 light sources with lower intensity light in each one of the 300.

This guy has to just be trolling here. Everyone is aware that a 600w LED will put out higher PPFD than a 650w HPS.
Individual diodes doesnt matter here what so ever.

With multiple light sources, you get the advantage of light hitting the plant and deep into the canopy from multiple angles. With a singular light source, you will always have a strong center hotspot and shaded areas in the inner canopy.

and i posted an article that shows cannabis does better under 300 different light sources than a single point light sources. that's based on science , not feelings or beliefs.
read it plz
