Frequently Asked Questions about Purple Cannabis Strains
What are purple cannabis strains?
Purple cannabis strains develop violet hues from anthocyanins, triggered by genetics, cold nights, light intensity, or stress. They’re prized for visual appeal, terpene richness, and relaxing effects.
Which purple strain is best for beginners?
Purple Punch Auto Fem is ideal – autoflowering, forgiving, and ready in 8–9 weeks with strong relaxing effects.
What makes cannabis purple?
Anthocyanins (pigments) cause purple colours in cannabis strains. Genetics + cold nights (10–15°F drop) or stress activate them. Our Purple Punch Auto and Purple Kush lines show consistent expression.
Are purple cannabis seeds legal in the UK?
Yes – all Tastebudz purple cannabis strains UK are sold strictly as souvenir/collector items for genetic preservation. Germination is illegal without a Home Office licence.
Do purple strains have higher potency?
No – colour is aesthetic. Potency comes from genetics and growing conditions. Our purple cannabis strains UK range from 20–28% THC depending on variety.
When should I harvest purple trichomes?
Purple colour doesn’t determine harvest time – check milky/amber trichomes, bud density, and pistil colour. Most of our purple strains finish in 8–10 weeks.
