could i move plants from outside to inside for just a couple hours?

Hey my plants are about 2 weeks into flowering and i have some family coming to my house and i was wondering if i put them in the garage would this harm them in any way ? i was planing to put them inside the garage at about 7am then put them back outside at like 8 or 9???

It may cause stress but its not going to kill them

its not that simplle...
HOW long are you doing this?
8 or9 am or pm?
