Apart from saving money on the electric bill or as a method of mitigating higher temperatures. what good reason is there to not grow autoflowering varieties on a 24 hour light cycle? With a limited time to get them finished up, why not be growing them on overdrive the whole time?

It all comes down to personal preference. GrowWeedEasy suggests an 18/6 light cycle but acknowledges that there's no scientific proof autos need a dark period. Now, anecdotally my plant seemed to perk up & look great after a 4 or 6 hour dark period so I choose to do 20/4 in veg & 18/6 in flower. But other growers report success with a 24/0 cycle. As long as your grow space is staying cool & you don't mind the additional electric costs, there's no harm in 24/0.

Any plants I've had seemed to flourish more with a small amount of dark resting time. Just because the lights are off doesnt mean they arent growing. You'll avoid light burn. And really 20 or 18 hours of light will give great results. Happy growing.

Just study the photosynthesis process and you will understand what happens during the night....

There is still an advantage of giving plants a dark cycle, even autos. Personally I usually run my autos under a 20/4 light cycle. That works well for me. Good luck!

I don’t recall which breeder chimed in on this point in another diary, so I don’t want to name the wrong person. His point was that even autos need a few hours of dark, and recommended 20/4.
Many sources claim ‘leaves grow in light. Flowers grow in the dark’

Two words, diminished returns. Stick to 18/6. Good luck!
