Propagation and transplant planning

Follow product-specific preparation instructions and manage moisture, humidity, temperature, and fertility for your crop. Avoid assuming that all plug shapes fit the same tray. Support the plug during handling and base transplant timing on root development rather than a fixed schedule.
