any good hiding tips out there?

I live with my mom,and she dosent even know what the plant is.I told her that it's a sun flower and i found the seeds in the ditch.Now she getting curious what is.But my dad has moved out,still around.If he found my plant...im done.But he never comes to my house no more.But after I get my White Widow seeds im gonna grow it in my attick.Pretty stuffy though.I gotta do alot of work.Can't grow it up there in the summer it's like 90 dergress up in there.But im planning to tell my mom what the plant really is when im finished harvesting.
