Popular Regular Strains in Portland:
- Original Skunk #1 (Sensi Seeds) – A classic with balanced effects.
- Durban Poison (Dutch Passion) – A pure sativa landrace.
Feminized Seeds
Genetically altered seeds known as “feminized seeds” solely generate female plants, hence there is no need to identify and remove males. They are the most popular choice for growers seeking buds rather than seeds.
Characteristics:
- Gender Ratio: Nearly 100% female.
- Genetic Stability: High, but slightly less than regular seeds.
- Breeding Potential: Limited (since no males are produced).

Best for:
- Growers focused on flower production.
- Indoor and outdoor cultivators who want a hassle-free experience.
Popular Feminized Strains in Portland:
- Blue Dream (Humboldt Seed Organization) – A sativa-dominant hybrid with sweet berry flavors.
- Girl Scout Cookies (Blimburn Seeds) – A potent, cookie-flavored strain.
Autoflowering Seeds
Autoflowering seeds contain ruderalis genetics, allowing them to flower based on age rather than light cycles. They are fast-growing and ideal for short growing seasons.
Characteristics:
- Flowering Time: 8–10 weeks between planting and harvesting.
- Light Requirements: Can grow under 18–24 hours of light.

- Amnesia Haze Auto (FastBuds) – A sativa-dominant auto with energetic effects.
Photoperiod Seeds
Photoperiod seeds rely on light cycles to trigger flowering (typically 12 hours of darkness). They offer greater control over growth and higher yields than autoflowers.

Characteristics:
- Flowering Trigger: Light cycle change.
- Growth Time: Longer (10–16 weeks).
- Yield Potential: Higher than autoflowers.

CBD-rich seeds are bred for high cannabidiol (CBD) content and low THC, making them ideal for medical users.
Characteristics:
- CBD:THC Ratio: Ranges from 1:1 to 20:1.
- Effects: Non-intoxicating, anti-inflammatory, and relaxing.
- Medical Uses: Pain relief, anxiety, epilepsy, and inflammation.
