Regardless of spectrum, there's an LED issue that, if I had to guess one out of 100 plants has.
And unfortunately my own self created F1 lineage, my pace blasters, do not like LED panels. They don't like how unol full spectrum. They don't like low umol blurple either. Used to use those for veg.
Some plants for whatever reason, have to be a lot further away from an LED panel and they should have to be.
I'm leaning towards some plants not knowing exactly how to handle intense light that's not coming from ionized plasma like sunlight, HPs, and florescent does. Gas is in the form of ionized plasma are generating that light in those cases. With LED panels that is not the case.
My peace blasters can take more than 2,500 ppfd. They couldn't take more than 1200 under an LED without burning. I could grow those plants close enough to a high pressure sodium bulb to bleach the tissue white and they wouldn't even show light stress underneath the bleached tissue.
I still use LED panels and I don't plan on going back, I just want to understand what's going on there with some plants.
There's several other plants on thcfarmer right now the behave the same with LED light as well.
I'm not trying to knock LED or make a LED versus HPS comparison, I'm just trying to wring all the information out of the context I can so I can learn something lol

So I started this deck for an elderly friend in late March. And it'll be done finally after today. Getting his last liquor shelves done. He's undecided if he wants the ceiling and lower half of the walls insulated. He doesn't think it'll make much difference in winter even if he plastics the windows. I think it will though. I framed it where it can be insulated and drywalled on lower half of walls, and ceiling if he wants to lol. Rj19 will slide right into the ceiling. And one 2x4 per panel down low and same.
I'm very proud of this one. Haven't been able to do anything this big before.
