Welcome to you! It's awesome to hear about you AND your dad getting into this together.
My dad passed about 2 years ago, and he was a big supporter of legalization and had many a fond memory of time with MJ. I regret not getting into it sooner so we could have shared experiences; it's great to hear you two are going to get to enjoy that!
This is a great place for newbies as well; lots of great support from VERY skilled (and shockingly humble) growers, and patient but diligent mods looking out for you. Don't be afraid to ask; I've probably started half a dozen different threads in the new growers area and received nothing but solid answers and support every time!
