plant later, smaller plants bud sooner?

so if i where to plant later (may or even maybe june) would i just have smaller plants that will still bud at the right time, or do i need to give the plants the proper time to fully develop?

Yes, you will have plants that go straight into flower but depending on where you live, if it gets cold, the buds won't be ripe until too late. Why would you do this? if you can't plant until just, get a quick auto.

well i would be doing this more for fun then anything, but im not looking for huge plants and i also dont wanna be growing for that long in fear of gettin caught. id rather just grow a few small plants and let them bud fast. noob question i know but how big would it get by the time of harvest if i planted in may. im hoping for 1-2 feet

also i live down south so no problems with cold weather

also another question... i hear helicopters every so often, what are the chances there looking for bud?

EDIT;
NVM this reply,thought you was growing indoor
