Pro-Mix BX vs Sunshine Mix

Which is better? Pro-Mix cost $38 versus $31 for Sunshine Mix, which would you buy?

I prefer Shunshine Mix #4 but that is just me

From what i read, pro mix adds things that help protect roots. They are both pretty much the same, but it seems as if more professional growers use pro mix. THey like the ability to know exactly what they put in since there is not chemicals already. Hope this helps. Good luck

Sunshine #4 never fails

Pro-mix on the east coast and sunshine mix on the west coast.........Alot of us don't have a choice.

and then i guess the midwest gets both? i can get pro-mix and sunshine mix
