A clearer framework for every stage of the crop cycle
The Grodan 5-Phase Model divides the cannabis crop cycle into five distinct phases, helping growers align plant development with clear root-zone targets, canopy priorities, and crop steering guidance at every stage.
The five-phase framework remains consistent across growing systems, while substrate, irrigation, and root-zone recommendations are tailored to each cultivation system. Choose the model below that best matches your growing approach.
