Locked Room Inside a House

if you make a mistake and let the police inside your house, but your grow is inside a locked room that is airtight etc. do they have implicit permission to go in there because you let them in your house proper or can you still refuse the search of that room provided they don't have a warrant?

Im pretty sure you can refuse entry but all it takes is one little clue and they'll get in there if they want.They'll end up saying some shit like well have you and you're family detained outside while they search the home.If you get them out of there without them getting in the room move whatever's in there cause they'll be back.

you can refuse a search, they will if wanted sit outside your house or something til they get a warrent saddly they can do it for just smelling it in the air

WTF did you let them in without a warrant for in the first place?Bad form...

like if your kid answered the door or something. i didn't let anyone in, i'm just suggesting a scenario.
