There are many, many good crosses of autoflowering plants out there now. AutoDiesel is a good one. Auto AK47 is another. Or, if your like us, we just breed our own. Take em to f-3 or f-4 and bring the ones with the auto traits as well as the other traits you want back to the original. Now, I won't say that these are as good as full size, long growth plants, but for some folks that need super stealth, they are a good choice.
