12/1 or 18/6

18/6!

18/6 is always suggested. I tried one on 24/0 but felt it wasn't really performing, a few days after I switched to 18/6 it flourished. 👍🌱

I've never grew autoflowers but I've read few studies about plant growth at different light periods and I'm going to test it myself. Studies show that cannabis in vegetative stage grows sturdier and has bulkier stems in 24hrs of light than any other BUT I've also read that flowering hormone is produced only during the dark periods of light so maybe 18/6 is pretty safe bet all the way or my advice would be to grow in 24hrs of light until you see her start to flower and switch to 18/6 and gradually lower it (15mins/week or 30mins/2weeks) to 12/12. Never tried it but this is what I believe would give great results and I'm going to do this with my first auto when I get it.

I've tried auto's under 24/0, 20/4, 18/6 and 12/12. I personally feel 18/6 gets the best result for the energy cost. Im using QBLED's. I would experiment with the light schedule to find your position. Good luck.

18/6 is the light schedule the most used when it comes to autoflowering. Under 18h you'll have some cal/mag overdrive and under 18h you can still try depending on your needs and environment, I am personally flowering most of my autos outdoor with a 12/12 schedule but it's not the most efficient

18/6 would result in a larger harvest than 12/12. Neither option is wrong but 18 hours of light will grow larger plants than 12 hours of light. Since your plants are Auto flowering variety they will flower on their own regardless of the choice you make. Hope this helps. Happy growing ✌️👊

It's suggested by most breeders to run them at 18/6 which is what I run and I get great results.
