On this week’s episode of Shaping Fire, host Shango Los welcomes back plant biologist Sarah Lane to discuss root structure in living soil, coco/peat and hydro systems, how roots function, what their various colors may say about their health, how and when to trim them, and best practices for creating a bountiful root system that will support massive growth and yields, including container choice, pH, watering, fertilizers and compost teas.
