When you get a mix do the seeds actually come labeled in seperate bags or is it a guessing game. I know this is most likely a daft question but i don't know the answer

. I love the idea of having a few different strains on the go, But not if I dont know what is what.
I have seen the sensi indoor mix in the uk420 shop. Has any one tried it? I need something to veg while I flower my first girls.
Peace
