This episode is part of the Foundations of Soil & Plant Science series — a curated set of conversations that still shape how I think about cultivation, soil fertility, and production systems. Originally released as Episode 20, this discussion with farmer and author Ben Hartman explores lean farming principles and how reducing waste, simplifying workflows, and focusing on value-driven tasks can improve both efficiency and profitability in cultivation. Many of the concepts in this episode translate directly to indoor and greenhouse production and remain highly relevant today.
