5 gallon bucket with a recycled organic mix with a few additions..Top dressed with living soil, Mychorrizae added around the base of the seedling..Tier planted..The top tier is some Roots Organic and Promix with some worm castings and lime..Just been watered with cal/mag, Mammoth P and 1 small feed so far with Foxfarm Big Bloom.
