I wanna line the bottom 2 inches of the the pots with something maybe sterile rocks for aeration open to recommendations.

I put perlite at the bottom of mine. Helps to keep gnats away.

I am a believer in not planning times for everything. Let the plant tell you when to transplant. Plus timing can depend on what, if any, topping and training you do.
