transerfing indoor plants to outdoors?

I have started some plants indoors under 600w M.H and was wondering if I can put them outdoors to finish it is june and I am in Socal lots of sun and 70 degreez temps would it be just as potent as indoor? and I am sure would yield more also.

Outdoors could yield you more since you will allow them to veg longer without space restrictions, but if the weather turns out to be shitty there is no way back unless you have them in pots and want to risk bringing outside (possible insects, pests etc.) to the inside. I would keep some inside just as back up if possible.
