brining clones outside

hello i was hoping someone can tell me some tricks to get some clones that are under a 18/6 inside to the outside. I live in LA so i don't have to worry about freeze but I'm concerned that around March 15 i only got 12/12 outdoors. So my question is what is the best way to bring these guys outside to 12/12 without them auto flowering on me, since they are sued to 18/6. I'm aware of hardening off but i'm extremely interested if anybody has had any success in doing this and if so you got any tricks?

thanks any help will be super important to me!!! thanks.

It would probably just start flowering. I mean for me, I wouldn't care if she started to flower. She could finish up before summer and then she would start vegging again. To me that would be great.

Wait to take them out till April 20th. By then the days will be much longer than nights so you wont have to worry about them flowering.

Unless they are auto flowers, in which case photoperiod doesnt matter, it flowers after X amount of time.

June 21st is the summer solstice which has the longest day light of the year and then the nights start to get longer until Dec 21st.
