yan402answered grow question 25d ago Hey growmie, gonna stop you right there — I've been growing for 25 years, and a huge chunk of that under 24/0. Especially with autos and vegging photoperiods. Not only do they grow just fine, they thrive. Bigger, bushier, faster.
That whole "plants need sleep" claim? It's outdated. Cannabis doesn't have a nervous system or melatonin cycle. It’s not a human, it’s a weed, and it evolved to adapt, not nap.
Yes, 18/6 works too. But acting like 24/0 ruins metabolism is straight-up myth. If 24/0 truly “damaged” plants, I’d have noticed it sometime in the last two decades.
Let people grow how they want, not everyone needs to follow 1990s forum dogma.
