No bottom paint vs hull slime

[240 LTS]

Because this is where everyone is, I thought I would get a quick response here.

I have a slip available to me in Kent Narrows. The bottom is not painted and I am not going to paint it. (I trailer my 24' bay boat.)
How long can I keep the boat in the water before I need to be concerned about growth on the hull. This time of the year I would think it could be longer then in the summer.
Will a week or two be ok?
Don't laugh, I've never kept a boat in a slip.

Thanks,
Jeff
