Purple Colour Is Cosmetic

[justicebzwieg]

Cold nights late in flower turn some CBD strains deep purple, and the effect looks impressive in photos but changes nothing about cannabinoid content. Breeders lean on this for marketing, and a few lines are genuinely colourful at any temperature. The strain descriptions on https://calmcbdseeds.com separate genetics that colour naturally from those that only do it under stress, which stopped me from chilling a tent for nothing. Dropping night temperatures too far also slows the final swell, so the trade off is real.
