Definitely something to keep aware of. I would also expect tech progress as well as competition to emerge shortly if there is anything to it.
Not discounting out of hand. Will watch for reviews.
Some of my older LED panels with mostly discrete Red/Blue diodes used very inefficient diodes, even the “Big Name” stuff. Better, more efficient diodes are widely available now, even cheap board lights are so much better.
White LEDs are phosphor coated blues so usually plenty of blue. I don’t think the wilting is directly related to any white spectrum. Been raising plants with mostly white “full spectrum” LEDs for over 10 years here, never experienced that wilt from lights.
Got a Cinderella Purple in early flower wit 2 Genius Juice and other projects. Had em both before and ordered more GJ when CP was out of stock.
Try HEKA, ever had a more potent girl.
