m0useanswered grow question 2 years ago 6 Key Points From Bugbee’s Interview on Pre-Harvest Lighting:
Photosynthetic energy is used to synthesize sugars that are used to make terpenes and trichomes.
No lights = no new energy = plants are not synthesizing new terpenes and trichomes in the dark.
During dark periods, plants consume accumulated sugars from the light periods.
Cold temperatures reduce the volatility of terpenes, which preserves existing terpenes (but slows down synthesis of new terpenes).
Could be the decrease in temperatures, not the lack of light, that is having the observed effect on overall quality of harvest.
The opposite extreme of 48 hours of darkness would be 48 hours of lights on but at a reduced temperature to protect/preserve existing compounds.
Its something that makes us feel good but has no real use in practicality.
