12/12 auto veg

yes

It doesnt matter. Its about the DLI, i dont know how there can be so much nonsense about a topic thats so clear. No wonder we deal with more myths than facts in cannabis growing. Pathetic. You can give that DLI in what so ever hours, but autoflowers can slightly take more light than photos probably thats were the 18 hour shit comes from. Also the nightcycle is as important as the day. They need to sleep and 12 hours are better than 6, if you have the power to give them the DLI in 12 hours. I give mine 16hours atm, but thats due to my LEDs, dont have more power. preferably i would sink down to 14hours light a day. All this rumors make me sick, since even I still fall for them.

Hi growmie, during my first grow I was growing in the same tent an auto and a photoperiod lady. So my Orion had a second part of her life 12/12 and both did pretty good. They produced more than my current autos under 18/6 for some reason.

If you need to do 12/12 to make it flower, you need to keep it on 12/12. If this is the case, you have a photoperiod, so treat it like a photoperiod as they probably screwed up packaging or had some unwanted-pollen contamination in their breeding process etc. If you are using 12/12 because it is residing next to photoperiods in flower, that is fine too -- This assume same DLI given as before. DLI is what matters, not hours of operation - given common sense... don't try to give 40DLI over 1 hour of operation obviously, lol. But, whether it's over 12, 14, 16, 17, 20, et al it won't matter much. DLI is what dictates yield along with CO2 (max dli is limited mostly by co2) Daily Light Integral - the proper way to measure how much energy/light you provided to a plant. hours of light alone is an incomplete picture.

Hello bundabl, Yes when autoflowers were new on the market I did some test grows with light on/off - 24/0 - 20/4 - 18/6 - 12/12 20/4 grows more during vegging but grams per used wattage 18/6 is slightly better. 12/12 did not grow that tall and for that reason and less light during flowering does not give a great yield. My advice for best result = 20/4 during vegging and 18/6 during flowering. Happy Growing Buddy! 💚
