@UncleRomulus and @MIMedGrower and anybody else i can ask: since this old dog is learning new tricks, may i ask what you do not like about the LEDs? I always used HPS and metal halide but damn the right LED sounds like a big improvement. I'd very much appreciate your thoughts...
There is virtually nothing you’ll not like about leds. But if you need negatives, lack of uv radiation is considered by some as a negative. Tho you can supplement uv leds for that. As said far red can be supplemented too. And if you provide far red in veg plants will stretch much more, like under hps.
Another downside, if you’re growing in a cold climate would be the lack of heat output. But again this is actually a positive thing. Can’t really think of any negatives besides these.
Ya I’m sold on some cxb3530s or 3590 s myself. Just old school and I use what I have. I’m setting up a space that will use 750 watts hps, 2x 315 cmh and 4 x 100 watt cobs in the corners. I like my lighting like I like my ladies.. weird haha@UncleRomulus and @MIMedGrower and anybody else i can ask: since this old dog is learning new tricks, may i ask what you do not like about the LEDs?

I will advocate for cmh tho over most lighting. It turns out most potent, fragrant buds as a stand-alone that this ol bastard has ever had.
For example, buddy bought a nanolux 315 vert cmh fixture. 3 bills. Throws a phili Agro bulb in.. 1 Hundo.. damn tho does that thing seem overkill I’m a 3x3. Would cover 4x4 no prob. Now tell me.. 315 watts and 400 bucks later and your yanking an lb of best weed you’ve ever grown out of a 4x4.. one fixture (runs so cool you can have your hand an inch from the bulb and not even hot.)
LEDs have come a long way and I like them. What’s not to like,?
Just heads up tho, hid is not dead and that tech hasn’t stood still neither. Still, companies are working hps and mh even improving. Seems crazy but ceramic hps could be cool is they cut out all that heat in the spectrum somehow.

Love this! Did you do much reading or did you pick this up from observation? I'm a bookworm so i'm reading a bunch of research that confirms that the blue end added to the red and far-red does reduce stretch more than just red alone--and it's the combo that signals the plant to flower earlier and for less time. So i'm seeing across the literature that there needs to be a combo of wavelengths. I hadn't heard of the Emerson effect--apparently there is a secondary Emerson effect too. I KNOW NOTHING--I'M JUST READING. I LOVE THIS DISCUSSION. Apparently the far-red has to be supplemented by a shorter wave-length (blue is a shorter wave right?) because the quantum yield of photosynthesis drops at the far-red end more quickly than is optimal.
They're also saying that it's not just metabolic increases from optimal PAR that's doing such great stuff. It's that the metabolic optimization leads to fuller gene expression...ooohhh the possibilities. THANK YOU ALL FOR HAVING PATIENCE WITH ME AS I SORT THROUGH THIS. WRITING IT HELPS ME. ALL RESPONSES WELCOME!
View attachment 856200 So my buddy sends a pic of his plant what is it bleached from light?

I might be wrong but looking for a nice par value across the entire canopy evenly distributed to get maximum light intensity to the tops of each plant to maximize flower size but apparently there’s even more cause spectrum plays a roll to bid I need to read more journals and learn about that next. There’s a cool YouTube video of a guy growing lettuce under different colored lights and they all respond different. I’m gonna start there. I would post it but it’s not copying for some reason.
apparently, not just different species do best under differing protocols, but different cultivars want different arrangements too. it's not one size fits all. i'm attaching a paper you might find interesting--the experiment is well-designed. many experiments with cannabis are not--alot is by people who either don't know herb well enough or people who don't know research design well enough.
Bro you say hid is not dead but at the moment most high end leds have higher umol/j output and when you apply the mccree curve, they produce even higher efficiency. Sorry, i know people love their cmhs and they seem like they are pretty cool but leds are just beginning their journey. My led grown buds are so fragrant i’m actually worried a bit about arousing unwanted attention to myself while they’re drying. Just my 2 cents.
Cool story bro.. doesn’t real negate mine but glad your happyBro you say hid is not dead but at the moment most high end leds have higher umol/j output and when you apply the mccree curve, they produce even higher efficiency.

How does it help and how far away should you move them and when?People say how fragrant and tasty my hps bud is compared to even their outdoor grows. And i know it is more potent than samples i have tried. But it did not used to be. I have had much practice now. :)
The lighting of course has effect but envirenment and the individual grow has more influence in my opinion.
Moving the hid bulbs away from the plants during ripening helps quality immensely.

@MIMedGrower , I leafed through that article on the emerson effect, and couldn't really draw much of a conclusion, other than that red light is helpful. How do you translate this into practice?
Nope, I am, it was @SinCityI dont remember linking article about emerson effect. Am i just stoned?
