Hi everyone i had to change the light cycle on my autos to 14/10 due to a heat wave that had my tent in excess of 40°c and the plants didnt like it. My question now is can i go back to 18/6 during flowering of autos so as not to loose yield? Wasnt sure if this might stress the pland and should i keep it on 14/10 untill they are done. Theres a lot of info regarding lowering light times but completely unsure about lengthening times. Any advice much appreciated 🙂

Welcome to the farm.

I saw a post yesterday about auto and light and apparently, autos are not fussy at all about light time changes.

Brilliant thanks for your reply so you think it will be fine to go back to 18/6🙂
Don't take my word as I know nothing about auto. I'm just saying that in the other post, almost all the replies seemed to agree that there is no big issue in changing the light cycle of an auto.

Your right to my knowledge. I don't grow autos either but they flower no matter the light cycle. I guess worst case is they could herm? But I doubt it.

The important part is getting them light... 2 ways to do that... longer photoperiod or higher intensity. For photoperiods you need higher intensity and for autos I would say a 20/4 or 18/6 is more ideal. Imo a longer period with slightly lower intensity than we run with photos would be easier on the plants.... its all about the DLI (daily light integral) basically the more photons of light we can give them while not giving to much the more energy they can make and use for growth and buds.

I'll tag a couple auto growers to see what they say but I'm pretty certain your on the money here.
