- Extending lighting from 12 to 18 hours can increase yield by up to 20%, depending on timing and cultivar
- New light recipe enables control over the potency of cannabinoids/amount of active substances
Eindhoven, the Netherlands – Signify (Euronext: LIGHT), the world leader in lighting, and Wageningen University & Research (WUR) have created a light recipe which extends the flowering phase of medicinal cannabis, leading to higher yields. By upping the photoperiod – that is, the length of daylight – from 12 to a maximum of 18 hours per day, the yield can increase by up to 20%. Timing is crucial in this: it must be a pre-harvest treatment, and the right moment differs per cultivar.
Dr. Céline Nicole, senior plant specialist at Signify, says: “We have developed and patented a ground-breaking light recipe with which we can safely extend the daylength without interrupting the flowering phase. To successfully achieve this, the right moment and length of time in which to raise the light sum is very important.” Applying light for a longer period of time and generating higher yields means that growers can improve their return on investment on their LEDs.
