1st time

I had this crazy idea not sure if its original or not though

I am planning on growing outdoors but need to know if this is a stupid idea

Tree Growing
-I will be growing mj at the top of a tree. Since no one will be climbing it and i have an idea how to easily climb it no one will get up there
-Where the tree splits I am making a flower pot basically and covering the bottom with leaves so it looks like a nest or nothing.

What do you guys think of this?

 

Thanks!

To get started what will i need?
Im not sure if it will get enough light from the sun so should i put a light up there?
Where can i get seeds from/are seeds from my dime bag good?
