So just wanna hear opinions on both light cycles 18/6 and 20/4 for autoflowers feel free to post some pics as well
As they don’t care about a light schedule, I would run it at 18/6. Just remember plants need a rest just like we do.
I say it depends a lot on the light you are using because plants can only process so much light in a day so there’s a point you could be wasting your electricity. I like autos because I can run my light at a lower intensity for more hours this makes temperatures easier to manage your light uses less power and will last longer
As a experinced auto grower and after seeing an auto grower poll on another site 20/4
Like @MeEasy said it has more to do with light.
The majority of home growers struggle to reach max light levels so 20/4 is a great scedule.
But really you should learn DLI
You can do that here
Be sure to give the thread a like if you learned something
