In practice, rooting cuttings and growing young cannabis plants is often a process that is far from uniform. Better performance in this crucial cultivation stage has a major impact on the final results. The root development can be controlled better by means of a dynamic light recipe, resulting in a shorter cultivation time, more homogeneous growth and better-quality flowers at the end. Due to the shortened cultivation time, the number of cultivation cycles can reach up to six per year. An additional advantage is that the use of rooting hormone powder, which is not permitted in some countries, becomes unnecessary. In addition, rooting hormone chemicals can sometimes hamper the proper root development.
Signify has developed dynamic Philips LED light recipes (spectral tuning) for better results in the rooting and growing phases of cannabis plants. Specific control of root and shoot development results in faster, more uniform plant development in the vegetative and flowering stages. The faster shoot development and better shoot quality lead to higher yields with a shorter cultivation time. The key to success is a light recipe with a specific ratio of red and far-red light during the root induction phase, in combination with the right light intensity. Dynamic grow light is also a powerful control tool to influence plant structure (morphology) during the vegetative growth phase.
