In some cases, a plant may produce purple tones in response to intense, direct light (on buds and leaves). Although we’re not sure exactly why it’s possible this may act as a sort of sunscreen for the plant! The importance of light levels varies on a strain by strain basis.
- Choose Colorful Strain (Most important!)
- Choose Strain that Produces Very Dark Colors (if you want buds to maintain color after being harvested and dried)
- Temperature – Warm days & cool nights
- Bright Light – Strong light levels can help bring out color
- PH at the Roots – Some strains may express colors at higher or lower pH ranges
- Pistils (Hairs) – some of the color remains after drying/curing
- Calyxes (Buds Themselves) – very strong effect on final color
- Leaves – relatively small effect on final bud color since many are removed by trimming
- Trichomes – small effect on final color
These buds were mostly pink at harvest, but the color doesn’t go all the way through the buds.
Dark Devil Auto is another fabulous auto-flowering strain by Sweet Seeds that turns a gorgeous purple or even a deep red.
For the most significant final effect on your dried and cured buds, you want to choose a strain where as many parts of the plant as possible are colorful. So ideally, you want buds where the pistils and calyxes (which make up most of the final color) are both vividly colored. If the leaves and trichomes are also colorful, that will improve the effect even further.
This outdoor cannabis plant has turned purple everywhere it received direct sunlight. Splendid!
- Warm Days (75-80°F / 24-27°C)
- Cool Comfortable Nights (65-70°F / 18-21°C)
