temp questions

i live in southern california and i want to grow and outdoor plant.
i have 2 plants about a foot each .
and i want to kno if i can move one outdoors.
its around 75 degrees at 3:30 pm and at night get to the low 60s.
can a plant handle that?

I dont see why not, typical temperature is around 65-75 or so.

Just don't below 55 degrees and you should be pretty safe.

will they get enough sun considering the days are still getting shorter? it may send them straight into flowering

im pretty sure the spot im doing get sun the whole day
and it hasnt been getting bellow 55 and what if i have them in a spot and put a 400w grow light poiting at it and have a time so it switches on at night?
would that work??
