Too short and too bushy

Reason for this will be the 2700k spectrum for the 1000w HPS and the distance required for it to be kept from the canopy.

600w LED are usually dual spectrum or switchable spectrums so you can tailor it to your plants needs and keep the distance between fixture and canopy shorter due to less radiant heat energy being emitted.

you are correct, 2100 K hps bulb for flower whereas MH can be 3000- 20,000 K
Obviously we are trying to mimic sunlight.

Incorrect.

I grow under 6500k T5's. Absolutely no stretching. Nothing but short stout plants.

xtsho you are correct 6500 K is in the orange/red spectrum but my flowering HPS bulb is 2100 degrees Kelvin so I'm confused.

6500 K is in the blue spectrum and considered daylight.

Color temperatures over 5000 K are called "cool colors" (bluish), while lower color temperatures (2700–3000 K) are called "warm colors" (yellowish).

Daylight has a spectrum similar to that of a black body with a correlated color temperature of 6500 K

Yes it is true, the LED that you bought that obviously gave you with your obtuse reply stretchy plants were either a lot of absolute cheap shit or they were too far from your canopy, either way, GL, you'll need it, in life generally.

Ok sure, Didn’t mean to sound obtuse. I was just trying to point out that other things being equal, the more red the more stretching , the more blue light the less stretching. Also with high amounts of blue light you tend to reduce leaf size.
As for my light, My lights are custom made using Samsung strips as a base light, making up 75% of total output, augmented with 3 watt chips, 390 nm-485 nm on one channel and red, photo red and IR on another channel and far red on another for end of day. All on separate dimmable drivers. Also just added 14% UVB bulbs.

And I never said 6500 k was in the orange/red spectrum. I know 6500 k is in the blue spectrum. These are the lights I use.

now I'm even more confused. I do like your custom light setup mimicking the sun's travel.

DAMN! Really? Didn't know that. That's very interesting if true. I wonder why's that for LEDs...

Because 90% of the led's on the market have a wonky spectrum with waaaay too much Blue and even the most popular board lights have refused to incorporate Far Red to date. :peace:

I think I'm getting wavelenght and Kelvin scale confused. Before LEDs, I used 1000w MH for veg and 1000HPS for flower. MH appears white and HPS appears orange to my eyes.
I must correct myself when I stated earlier "white" light should have been sunlight is made up of all colours of the spectrum. I was stoned at the time:-)

Yea, I understand this, but it's not what I'm dealing with. Don't want to show off, but the LEDs that I am using are considered one of the best at the moment. It's a genuine QB made by HLG themselves, no wonky spectrum for sure...

Thank you, I really appreciate everyone's effort on this thread, even if there were a bit of contradictory opinions, no hard feelings, I hope.

And yes guys, I already know the science of blue light for veg, red for flower, yada-yada-yada. I've been growing plants under both blue and red spectrums, and they never grew so compact like now. Still a mystery for me...

Is it the same strain and pheno that your growing now?

Is it clones from a mother donor plant?

If it’s seeds it could a phenotype that you’ve seen.
