HPS vs. LED Grow Lights — Which is Better for Growing Weed?

You ask the wrong question,
Penetration is an effect of a stronger wavelength source minus the obstruction it has to go through, my optimal is down to the soil like nature but I know this is very hard to achieve with just changing light sources, it sure can help, depending on the app
Again, I will repeat it many times cuz u don’t read, you scrog your led grow or any other method to keep everything at optimal levels, and it works most of the time but my simple question is was from the get go, is this initial output of each is enough ?
To answer that question one can only answer himself, you say a and I say b, I believe what I saw and you believe what you saw
Not gonna change.

And when I say optimal, don’t get me wrong, you are optimal in relation to your hardware, not the sun in anyway.

Bro, the problem with your theory is that you decided it was true before checking out the science, and you are now unwilling to be wrong. Your hard-headedness is likely your biggest downfall in life.

Honestly I don't know how someone can be disappointed with Cobs & led Qb's. It takes alot to impress me & I find the current led tech a fascinating artwork. Like how did they ever think to come up with such ideas & then to actually implement them. Kinda speechless & feel some what honored to be able to have such technology. Literally we moved the sun inside to use. If I ever have a grow issue I never contemplate that maybe it is the light. Because I know that's covered. I then proceed process of elimination & check temps, rh, vpd, ec, ph, run-off ppm & or check for pests or any other types of stressor. Yeah sometimes I may need to adjust light height & that's fairly straightforward, but I've never questioned the quality of light being provided. Simply because I know its getting all the correct types of spectrums & that light meters don't lie. If my end product result is sub par , I can't blame my equipment or Plant genetics.. I can only blame myself, & to learn from my mistakes, adapt & overcome.

I remember reading in some trade publication that “scientists had reached a breakthrough on the predictability on the effects of specific phosphors on blue light LED”, everything changed dramatically soon afterwards with White phosphor LEDs and so here we are.
Ten years ago I had some awesome Blurple going on.

That, or maybe I’m right and you have a hard time accepting it ;)
I know it’s hard to invest a lot of money on hype products that don’t really live to their claims, it’s much more harder to convince someone that is already neck deep into the LED game that maybe just maybe, someone took him for a spin... that’s ok though, this is a discussion about light, not about who is wrong or right, you decided I’m wrong, I decided your wrong lol does it matter ?
The most important thing is sharing knowledge, even if doesn’t comply to your own narrative.

LOL, bro I have HPS fixtures, CMH fixtures, and different types of LED fixtures. I didn't even pay for a couple of my fixtures as they were sent to me for free by the manufactures. In fact, I'm about to pull down my current rig of CMH plus LED boards to put up some bar type fixtures, because they are better to run this time of the year, now that it's warm. I run the CMH plus LED boards during the cold weather, for the added IR heat from the CMH. I've seen the differences under different lighting, and while I still have my HPS lamps, I have no reason to run them. If the quality was truely better under HPS, I'd get rid of all my LED fixtures today, but the reality is that I've had better yields and the same if not better quality under LED vs HPS. I ran HPS for years before running LED. I also started running LED very early in the game, and have blurple fixtures and old cob fixtures, that indeed are crap. Those fixtures were a poor buy, but I did get a couple of decent runs out of them before switching back to HPS. At this point however, modern LED fixtures are much better than HPS fixtures for growing. If you want top decide that I'm wrong, then that's your choice, however you are also deciding that experts on the subject are also wrong, and that College horticulture textbooks are also wrong. That would be kinda weird if you were right, and all the experts were wrong though. So far you've shown zero evidenct that you are right, but there is plenty of evidence that says you are wrong.

Oh, and when do we get to see some of your HPS grown buds, so that we can then post our LED grown buds that have more tricombs than yours?
