flowering indoors to outdoors

hi, i have a plant that i would like to start flowering indoors than put outside. my question is, since they normally start flowering here july 22nd, if i start flowering them before this inside than put them outside say july 4th, what do you think they will do?

as long as the photo period remains 12/12 or less i think the plant should continue to flower , and if you have some nice sunny days prolly better than inside. just make sure where your putting your plant is as sterile as possible. or find a way to deter mites and aphids

ok thanks.
