Ppfd for autoflowers in 24/0

300-350 But 24H light cycle isn’t recommended

Refer to a DLI table.. shoot for 35-40 to start, but then you'll have to adjust based on new growth as always. Can't skip that last step because 'max' DLI is different relative to local variables as well as some genetic diversity in that regard. The same DLI over 24h will not outyield it over 12h. DLI is what matters, not hours. hours is 1 part of the equation. new growhth -- too tight, reduce... too stretched, increase. Simple as that. The DLI target only ever shortens that learning curve. You may find seasonal idfferenes as far as how much light a plant can tolerate per day unless you tightly control the climate all year. CO2 is th elimiting factor and there is no circumventing it without adding more. 1200-1300ppm atmospheric co2 levels and you an push to 50-55 DLI range. As with a plant outside, if you force it to adapt to more, it'll merely mitigate the excess and thta will in turn waste a bunch of electricity. Ther's no shoving a square peg through a round hole, here.

I AGREE WITH DAT ORGANOMAN!!!!!

NEVER grow at 24/0..............All cannabis plants NEED "sleep"...............18/6 is optimal. There are certain metabolic processes that can only occur during lights out/night. Without a dark period, these processes can not occur, meaning you will have plants with a messed up metabolism. A plant with a messed up metabolism will never be as healthy as a "normal" plant. An unhealthy plant will never produce the best quality flowers that it is capable of. Anyone with a basic knowledge of plant (cannabis) biology would understand why growing a plant without "sleep" is wrong. The myth that it is ok to grow at 24/0 needs to be called out for exactly what it is......a myth.

For autoflowers on a 24/0 light schedule, a good PPFD is about 200–300 for seedlings, 300–450 for early veg, 450–600 for late veg, and around 600–800 PPFD during flowering, since higher levels are usually unnecessary without added CO₂.

salut. je vais répondre a ta question mais avant tout je te déconseille pour un meilleur rendement de le faire. cela stresse la plante . elle a besoin de se reposer un minimum. Si tu fais 24h de lumière (24/0) avec des autofloraisons, il faut baisser le PPFD par rapport aux cycles 18/6 ou 20/4, sinon ton DLI (quantité totale de lumière par jour) devient trop élevée et ça peut stresser la plante. Voici les valeurs du PPFD idéales par stade pour du 24/0 : Plantule (0-10 jours) 150 – 300 PPFD Lumière douce pour éviter le stress et favoriser les racines. � Graines automatiques Croissance (végétarienne) 350 – 500 PPFD Avec 24h de lumière, ça suffit largement pour pousser fort. � Graines automatiques Floraison 450 – 650 PPFD (zone idéale) La plupart des cultivateurs restent autour de 500-600 PPFD en 24/0 pour éviter le stress lumineux. � Photone - Mesureur de lumière horticole +1 Résumé simple (24/0) Plantule : 150-300 PPFD Croissance : 350-500 PPFD Floraison : 500-650 PPFD Petit conseil de cultivateur : Même si 24/0 fonctionne, beaucoup de cultivateurs préfèrent 20/4 ou 18/6, car les plantes bénéficient d'une petite période d'obscurité et cela réduit également la consommation électrique.
