New to Bubble Box few questions

Hello,

I just order my Bubble box after learning about them 2 nights ago. New to the whole kief collecting i have been doing a little with me grinder, and looking to take it to a whole new level, and start off with the best right off the bat. So I am looking for techniques for a newbie. 1st should I store some stuff in the box. 2nd how offten should i shift the different screens. I am looking into get a portable vaporizer and was wondering if that will work with the kief or do i need to go to a bigger vaporizer
3rd what do you do with the keif left on the other screens is that still good. i order a space case pollen press and was wondering if i even new if with what i am looking to do.
Finally is it ok to leave the kief in the box for a little without shifting the screens or is that harmful to the screens.

Thanks- jackson
