You might want to check your laws again... Washington actually looks like the shittiest place to grow out of all the states! Can only grow four if not registered with your city and you can still be arrested if you are seen growing. Wich means even though there isn't a written law, you will still...
I saw earlier in the post about doing greenhouses to battle the weather. If your new to them just make sure you have plenty of ventilation!! That is key to making a greenhouse work properly. Good luck to everyone this season!! Have a Dank Day!!
Larger the better. Get the biggest that you can move. Put em on wheels if you have to. Or make sure well working handles are on the pot. Happy growing!!
