On January 22nd in Warsaw, a training on popular growing media and LED lighting in indoor cultivation took place, aimed especially at the hemp industry. The event was organized by PuroCanna, a company dealing with the cultivation of hemp in strictly controlled environment – in an indoor farm. At the invitation of the organizer, the founders of Plantalux – Jakub and Rafał Lachowski, presented the participants with basic information about lighting in plant cultivation. Issues such as the uniformity of lighting, the beam angle of luminaires, the distinction between the ranges of visible and invisible spectrum, parameters closely related to the cultivation of ie VPD, EC or carbon dioxide concentration were discussed.

We would like to thank the organisers and all the participants for participation.
