>>2320231>>2320244Bruh. Since you're obviously so new to this, I'll edumacate you a bit out of sympathy.
Plants adjust their "skin" surfaces depending on the level and intensity of light they're exposed to. When you grow them indoors under an LED light, that's VERY low level light exposure and intensity, and as such, the plant grows accordingly, with weak cell surfaces. However, the sun, being FUCKHUEG and HOT AS HELL, is far more intense than an LED, so when you take a little-ol' plant with weakly adjusted cell surfaces and plop them right into the BLAZING hot fucking sunlight, the cell walls can't cope with the intensity and are destroyed almost instantly. This as opposed to plants which grew in the sunlight from birth where the cell surfaces adjusted accordingly to the intense light and became stronger.
This is why there is what's called "hardening off", where plants previously exposed to low-level low-intensity indoor light or shade are given brief successive periods of slightly stronger light each day, in order to allow the plant to build up that new light tolerance. So from indoors, you put it out in bright shade for several days. Then, you put the plant in a couple hours early morning or late evening sun for a few days. Then, you increase that a little bit for a couple days too, until finally the plant can withstand the full day's sun, even in the harsh as fuck midday sun (depending on plant species, of course, not all plants can handle midday sun even with hardening off).
Do you get it now?
