Commercial Cannabis Propagation: Building a More Repeatable Clone Program

A rooting product cannot compensate for an inconsistent propagation process. Commercial clone performance depends on the interaction between cutting quality, rooting media, moisture, environment, sanitation and handling.

Standardize the mother-to-cutting process

Define cutting location, size, tool sanitation and the maximum time cuttings can remain out of the propagation environment. Variation at this step follows the plant through the entire rooting cycle.

Control media moisture

Propagation plugs need enough moisture to support the cutting without remaining continuously saturated. Uniform wet-up and consistent tray handling reduce differences between plants.

Use rooting products according to the label

Plant growth regulators and other rooting inputs should be used at the current label rate and application method. More product is not necessarily better.

Manage humidity and temperature as a system

Air temperature, media temperature, humidity and light all influence transpiration and rooting. Avoid changing multiple environmental variables at once when troubleshooting.

Define transplant readiness

Use observable root development and plant condition rather than a fixed calendar day alone. A repeatable transplant standard improves downstream irrigation consistency.
