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.

Hey. I'm going to answer your question, but first, I advise against it for better yield. It stresses the plant. It needs to rest a little. If you're doing 24 hours of light (24/0) with autoflowering strains, you need to lower the PPFD compared to the 18/6 or 20/4 cycles, otherwise your DLI (total light amount per day) becomes too high and that can stress the plant. Here are the ideal PPFD values by stage for 24/0: Seedling (0-10 days) 150 – 300 PPFD Soft light to avoid stress and promote roots. 🌱 Autoflowering seeds Vegetative Growth 350 – 500 PPFD With 24 hours of light, that's plenty for strong growth. 💪 Autoflowering seeds Flowering 450 – 650 PPFD (ideal zone) Most growers stick around 500-600 PPFD in 24/0 to avoid light stress. 🌼 Photone - Horticultural light meter +1 Simple summary (24/0) Seedling: 150-300 PPFD Vegetative Growth: 350-500 PPFD Flowering: 500-650 PPFD A little grower tip: Even though 24/0 works, many growers prefer 20/4 or 18/6 because the plants benefit from a little darkness period and it also reduces electricity consumption.
