Has anyone gone from 24/7 to 12/12?

I've got my LED's on 24/7 never turned them off since they were seeds, they're now almost 2 months in and in flower ( purple haze autos ) , i was thinking of switching to 12/12 , my thought is that the plant might be like, whoa! dark! now light! lets get growing!!
Appreciate your thoughts and yeah i'm a little high :)

All it will do is hurt yield. I would drop them down to 18/6 or 20/4 just to give the plants time to rest. They actually do things during the rest period so good to provide some dark but any more than 4 to 6 hours will hurt more than help an auto IMO.

With autos it would just be a shock to the plants. If they're from a strain prone to hermie (I haven't grown purple haze, photo or auto) that could be enough stress to cause them to pop some nanners.

Edit: just googled it, there should be some purple thai in there, and thai strains are notorious for hermie traits

No it won't.

Do yourself a favor OP and do some research on the importance of darkness to a cannabis plant. Respiration during dark period is important and produces healthier plants.

No it won't.
Going from constant light to 12/12 suddenly? That would shock any plant. Especially in flower, when plants get more sensitive to any environmental disruption.
If he had a photoperiod it wouldn't be in flower yet, so it would withstand the shock better.

What lights are you growing with pics please, autos don’t need a light change the just need time. I’ve had autos go 3 months before flowering. But I see a lot of auto growers running shitty blurple light that could barely flower a plant

I'm using Mars Hydro Tsw2000 in a 3x3 tent with 4 plants, the main reason i was thinking of a light switch is to give the plants a break and also to see if they would increase yield and the tent is in my bedroom and i could do with some darkness at night :)........i'll post some pics later

Really? During flowering? Why would you do that?
Only reason I've ever heard to switch autos to 12/12 is to induce flowering in reluctant plants.
Because the photos needed to flower. I thought the autos would be done before the switch but they needed to finish and the photos needed to switch or they would be larger than I wanted. I have to work with plant count restrictions. But it's more flowering plant numbers.....I can only have two in flower. This way when the photos are vegging I can have autos flowering under 24.

If you have to switch to 12/12 it is not an reluctant auto, it's a photo
Yeah, from improper breeding practices. I was trying to keep to the subject. There are some that just need a kick in the pants to start flowering and can be bumped back up to 18/6 after it starts, but the only way to figure that out is trial and error and some revegged plants.
Some of the threads posted by guys who did that are successful, others aren't.

Not necessarily.
