Background
Blackberry Punch Auto is an S1, which means it was made by self-pollinating a single selected Blackberry Punch plant. That keeps the line consistent, so you get the same purple color and berry nose across your plants.
Cultivation Notes
This is a Type 3, CBD-dominant autoflower, so it flowers on its own with no light schedule change. Plants finish just 18 to 24 inches tall, one of the most compact sizes in our catalog, which makes it a natural fit for small tents, balconies, and discreet outdoor spots. It’s ready to harvest in about 75 days from germination. Check our Germination Guide for autoflower-specific guidance.
Additional Info
The deep purple buds and sweet berry smell give it real bag appeal for a CBD variety. Growers commonly associate Blackberry Punch Auto with a calm, relaxing character. Available in 3 to 50 seed packs.
Bred in-house by Triangle Seeds.
Frequently Asked Questions
Is Blackberry Punch Auto a Sativa, Indica, or Hybrid?
Hybrid
Is Blackberry Punch Auto an Autoflower or Photoperiod strain?
Blackberry Punch Auto is an Autoflower. Autoflower varieties flower automatically based on age, usually finishing 9 to 12 weeks from seed regardless of light schedule. No light timing required — they're ideal for new growers, fast turnarounds, and growing indoors year-round. Photoperiod varieties flower when the light schedule changes (typically 12 hours on / 12 hours off). They take longer but give you more control over plant size and yield.
How long does it take Blackberry Punch Auto to grow?
Autoflowers are the fastest path from seed to harvest. Most finish in 8 to 12 weeks total from germination, regardless of light schedule. Because they flower based on age rather than light changes, there's no separate vegetative phase to manage. Just plant, provide consistent light (18 to 20 hours a day works well), and let the plant do its thing. Check the strain details above for specific timing estimates, and visit our growing guide for tips on getting the most out of your grow.

How do I germinate Blackberry Punch Auto seeds?
Autoflowers need a slightly different approach because their roots are sensitive to transplanting. Start with a 24-hour soak in a hydrogen peroxide solution (1 part 3% H2O2 to 6 parts water) to boost germination. After soaking, plant the seed directly into its final container (3 to 5 gallon pot) about half an inch deep — do not use the paper towel method or start in a small pot. Spray the area around the seed to keep the soil moist, but do not soak the entire container. The key with autoflowers is to never transplant them.
