How do you grow cannabis to be purple?
Growing purple cannabis strains can be a rewarding experience, adding a unique and visually appealing element to your garden. While genetics play a significant role in determining the purple hue, environmental factors also contribute to this colorful expression. Here's a comprehensive guide to help you achieve purple cannabis:
Genetics: Choose purple-leaning strains, as they carry the genes responsible for producing purple pigments. Popular options include Granddaddy Purple, Purple Kush, and Blackberry.
Temperature: Exposing plants to cold temperatures (around 5-13°C) during the flowering stage can trigger the production of anthocyanins, pigments that give plants their purple coloring.
Light: Provide ample light, particularly during the late flowering stage. High-intensity LED lights or natural sunlight can enhance the production of anthocyanins.
pH Level: Maintain a pH level of 5.5-6.5 in your growing medium. Alkaline conditions can suppress the expression of purple pigments.
Phosphorus: Avoid over-fertilizing with phosphorus, as high levels can block the absorption of other nutrients that promote purple coloring.
Additional Tips:
- Phosphorous flush: Flush your plants with plain water before harvest to remove excess nutrients that could interfere with purple coloration.
- Hanging: Hang plants upside down after harvest to allow leaves to dry slowly, further enhancing anthocyanin production.
FAQs:
- Can any cannabis strain turn purple? Yes, but some strains are more likely to exhibit purple hues due to their genetics.
- Do purple strains have higher THC content? Not necessarily. Purple coloration is determined by environmental factors and does not directly affect THC potency.
- Why do some purple strains turn green? High temperatures during flowering can reduce anthocyanin production, resulting in a greener appearance.
- How long does it take for cannabis to turn purple? Purple coloration usually becomes apparent during the late flowering stage, typically around 2-3 weeks before harvest.
- Is purple cannabis more potent? There is no scientific evidence to support that purple strains are inherently more potent than others.
