Grow legally for a friend?

[Batfongrips]

Hey I have a question, if you live in the Washington state and you have a green card, is there a way that we can set it up so a friend without a green card in a better location could assist me with a grow for my plants at his house? I heard about that somewhere and I would like to check into it but have no idea where to find anything.

Give him a copy of your MMJ authorization and sign a letter giving him permission to be your caretaker. Be sure and read the laws to stay in compliance.
