HPS on left. LEC on right. The plants don't care. They transfer photosynthesis to the strongest wavelength.
We stoned growers think we see all kinds of stuff that isn't there. And as humans make excuses for our own mistakes.
The benefits are subtle. And unless you can grow a whole cycle healthy consistently you would never see any difference. And the light type won't help you if you can't.
No one has picked 100% blind which weed I have that was grown under which light. I have jars of before and after hps alone.
I like the natural light to work under and have noticed a subtle quality improvement. No magic.
These plants have been in the same spot all week.
Can you see a difference because of the light they are under? Hps corner looks ok to me. Lol.
If I never heard of LEC and had added another hps. Except for the red tainted room I hate I would never have missed anything.
I like them. And that is why I like them. Let's not pretend we are doing anything special to an adaptable plant. It is doing what's special.
