The Cultivation for Compounds II (CfC II) consortium has completed its first trial, with Cultiwool participating. As the two-year program moves into its next stage, seven trials remain with Cultiwool's objective to investigate how substrate choice and root-zone management contribute to medicinal cannabis cultivation.
The first trial included three root-zone treatments and compared Cultiwool Prime with Cultiwool Original. Early observations showed faster root development in cuttings rooted in Cultiwool Prime, along with strong early plant growth under the trial conditions
CfC II brings together cultivation specialists, researchers, breeders, and technology suppliers to develop knowledge about medicinal cannabis production. Led by Cultivators, Vertify, and World Horti Center, the project connects expertise across cultivation and processing, with attention to crop quality and resource use.
Cultiwool contributes the substrate perspective to this collaboration. Comparing Prime and Original within the research program creates an opportunity to assess plant development alongside the root-zone conditions recorded during cultivation.
Root formation is an important step in establishing cuttings. During Trial 1, cuttings were rooted in Cultiwool Prime showed strong root development. The cuttings were then transplanted into Cultiwool Prime and Original Blocks and provided the same nutrient recipe.
Prime is manufactured with a plant-based binder and is designed to support moisture management and root development. The observations provide a starting point for investigating how substrate properties and cultivation management interact. Further trials will help determine whether the early rooting response is repeated.
CARA MET sensors from SenseNL supported root-zone monitoring during the trial. These sensors measure moisture content, EC, and temperature within the substrate.
Combining root observations with substrate measurements provides a fuller picture than either source of information alone. Root photographs document development at a particular assessment point, while sensor records help describe the conditions surrounding that development.
The three root-zone treatments add another dimension to the investigation. Reviewing the treatment records alongside the substrate comparison will help guide the questions taken into the following trials.
Completing Trial 1 marks an early milestone in Cultiwool’s participation in the consortium. The next trial will build on these observations, with seven trials still to complete within the program.
Through this collaboration, Cultiwool contributes to a more practical understanding of the relationship between substrate, root development, and crop performance in medicinal cannabis cultivation.
