Ciao a tutti Secondo voi,partire da 24/24 per 2/3...

I have a degree in plant biology.............

NEVER EVER grow at 24/0! ALL cannabis plants, autos included, NEED "sleep" for a correctly functioning metabolism and to have a defined daily photosynthesis cycle.........just like Mother Nature intended. You will gain nothing by doing 20/4, except a larger electricity bill..........18/6 is optimal. Put simply, just do 18/6 from day one until harvest, it is the most efficient and most effective. You will not get any noticeable gains by doing what you are thinking about..........except a bigger electricity bill! Cannabis undertakes certain metabolic processes during lights out, without a dark period it obviously can not do these processes and will have an incorrectly functioning metabolism. Any plant with an incorrectly functioning metabolism will never reach its full potential or have peak health. It is an absolute MYTH that it is ok to grow cannabis at 24/0!

* first couple days is a possible exception... but you also don't try to give max DLI the first couple days after sprouting, so it's a unique context. Too much light is just as bad as too little. Goldielocks zone is the key.

The only reason to do this is if your light struggles to provide enough DLI. (daily light integral - read wiki for basic understanding) if you provide enough DLI over 16h, that's fine. OVer 18h? that's fine. The plant absolutely benefits from some length of darkness and absolutely does not benefit when you give it more DLI than it can handle. (this amount varies due to local variables - Temperature, Relative Humidity, and atmospheric CO2 levels) -- You must derive the 'max' through trial and error. Doesn't matter if you give that same DLI over 12h or 18h. Length of time is relevant but on its own is useless. Rate x Time = DLI. Number of photons absorbed per day is what matters. Adjust light intensity or hours of operation (both can have same effect) based on plant growth pattern. If nodes are too tight, reduce DLI. If nodes are too stretched out/lanky, then you need more DLI. The area you try to cover with the light will obviously be proportional to DLI too. Try to cover twice the area, all other factors remaining the same, then you have half the DLI across that larger area. hours and umol/s PAR are directly 1:1 proportional and area (relative to 1m^2) is inversely 1:1 proportional to DLI. You can infer this from the math explained in the wiki for DLI.

I'd only do 24hr for the 1st 2 days, then move onto 20/4 for a week then going to 18/6.

Hey there I would ajdust the schedule in these ways 1. I would only give the plant 4 or 5 days of 23/1. Then go to 22/2 for a week or so then go to 20/4 Personally I like to give plants a little less light the 1st few weeks then go hard at them after about day 15 to 18 I don’t like to go hard with the light from the start because in my opinion it makes all the nodes all squished together at the start and sometimes that’s a good thing but how I grow my plants I’m not main lining so I want them to have like .5 in to 1 in bettween the 1st few sets of nodes instead of 1cm or.5 cm It’s really all about preference and set up and how you plan to grow Good luch

Ps all the diaries are 24 hrs of light for Autoflowering until the end and 24 hours until switch to 12/12 for photoperiods. 🤞🍀♥️

Perfectly fine. Just 4 examples. #1 growdiaries.com/diaries/190515-royal-queen-seeds-apple-fritter-automatic-grow-journal-by-yan402 #2 growdiaries.com/diaries/172659-grow-journal-by-yan402 #3 growdiaries.com/diaries/235033-runtz-auto-grow-journal-by-yan402 #4 growdiaries.com/diaries/241785-kannabia-seed-company-candy-cream-go-fast-grow-journal-by-yan402

24/24 no! If you mean 24/0. They can handle it, but its not necessary. 20/4 ok. 18/6 ok. Would not recommend it. Nonetheless I sometimes do it to raise temperature. Just decide for one and keep it that way. Don't stress yourself for possible no effect on your harvest.
