Best lighting cycle for autoflower

Can anyone tell me what would be the best lighting cycle for autoflowering plants i have mine on 21hours on and 3hours off and they are doing well should i now increase the hours off darkness now they have started to bu

I personally run mine on a 12-12 once flowering
But honestly you can run whatever time cycle you wish with autos
I will add this all plants need a rest period


Thanks very much for your help mate

Sure any time
I know a few other of the Mods also fun the 12-12 cycle as well
The height of the plants will be determined by how close you keep your lights in most cases and size of pots your growing in as well
I play with my autos meaning I don’t grow them as my main crop I only grow my hem just for the fun of it lol
So I normally use 1-2 gallon pots

And found that 3 gallon pots indoors are more than enough
Happy growing any other questions just tag me and ask

the light pattern ive seen in here that makes sense to me is 24/0 first week or two, then 18/6 for 2-3 weeks, then 12/12 until harvesf


Thanks very much for the advice mate :+1:

anytime. we are all here to learn and help

I kept my autos on 20/4 under 400HPS/400MH combo. They did fine - 12 plants got me 8 months of weed. I did run into some nute problems, and I do think there is something to be said to going to 12/12 in flowering, regardless. It’s more natural.

A 12/12 photo plant is what you want it to be like, you just want one thing from the 24/0 side(Autoflower)
I like to run mine as close to photo light cycle if I can , I think the buds bulk more

I always thought 12/12 would sacrifice yield bc autos are on a clock and the more light the bigger the colas. But we learn something new everyday

Honestly Idk for sure. I put my flowering auto back into 24/0 and she started flowering again
