Is LEC the same as plasma...? I probably read about it at some point but have the memory of a goldfish after the accident.

i have read recently i think in maximum yeld that plasma has recently made some innovations. personally i think lep is still a few years out before it is a viable option for home growers

thats natural sunlight. were talking grow lights cmh has much much more than hps, blurple leds. some cob can have more depending on the chips used. for that mater cobs can also have far red flower initiators to. wish i was wireing savy i could build my own.

I think the question is whether the amount of UV inherent in CMH will actually make any noticable difference to potency. There's still a dearth of data on that subject, as far as I know.

i cant answer that all i can say is my stuff is better than it was when i used leds but my skill is better so wether it was the cmh spectrum or just better talent? i can say that i get sunburnt if im in the garden longer that 30 min ( i have a bald mellon lol)

Thanks for being honest. People's egos often drive them to make outlandish anecdotal claims. As we continue moving towards legalization across the globe, we're going to have the opportunity to conduct many more side by side studies with single variables. Until then, honest anecdotal statements are valuable when there is a dearth of evidence.

And yet the quality of my crops improved when I went to LED from those very same lamps.

Go figure.

Great. No doubt there are confounding factors for each grower, that's why this anecdotal evidence is important. I'm on the LED train but I have an LEC lamp that I will use until it's worn out (probably a couple years). I'll be supplementing that lamp with LEDs to fill my tent.

Ultimately, all of these lamps are capable of growing top shelf.

No, thats why its essentially useless. Because its simply too often contradictory. Evidence that contradicts itself is useless as such.

That's why people need to just drop the "this light source is best" bs that goes around the led forum so much.
There are many ways to get r done and it would be nice if we could all share what we are doing and discuss without the constant pissing match bs.
At the end of the day it is what's in the bag that matters. So many that claim to constantly be on the cutting edge and putting down those who use what they call "outdated tech" are the ones producing schwag. :eyesmoke:

If one is only capable of following prescriptive guidelines, I agree. I'm not interested in the LED/COB/LEC/HPS debate per se, I'm capable of drawing my own conclusions. I enjoy seeing the quality products various posters are able to produce with their set-up. I can take that into account while we wait for more papers to be published on a number of things: soil science, lighting technology, etc.

People act like pre-1900, we were incapable of recognizing patterns that affected our world.

I'm guessing you haven't had reason to digest large amounts of academic work but let me tell you, the majority is contradictory. Whether it's poor experimental design, bias or unexpected variables, there is a huge amount of data that rests on contradictory claims. When we lack controlled studies that block for all the additional variables, we move to the cutting edge fully aware there is a price to be paid for the adventure: time, money, crop, anxiety, etc.

I believe the majority of growers are looking for the magical element for "the best" cannabis cultivation. I don't believe such a thing exists, I want to see people's results and attempt to fine tune my system for a continually better product. Nothing more, nothing less.

One of the things that made the biggest difference for me was a bit of epsom salt in the nutrient mix. It didn't matter what the light source was, that was a helpful change.

You're quite right in that good results can be had under any of the lights mentioned. That said, I'm of the camp that includes efficiency as an essential parameter. LEC/CMH (on square wave ballast, which is the component that actually delivers the improvement) tends to be more efficient than other lamps, but LED is even more so.
