The shortest version: North Atlantic Seed Company's take on hybrid genetics, 8-1% THC, 8-9 weeks from seed flowering, easy grow.

North Atlantic Seed Company lists this at $37.80 — above the median of $31.46 across 15 listings. Pack options: 3-seed at $37.80, 5-seed at $54.00, plus larger sizes.

Lineage: a high-CBD photoperiod cut crossed back into ruderalis to lock in the autoflowering trait — that's the short version of how this one came together. The result is a strain sitting at roughly 20% CBD with THC held at 8% or below, meaning psychoactive effects stay minimal while the cannabinoid profile stays useful. Indoors, expect 350–450 g/m² in an 8–9 week seed-to-harvest window, which makes it one of the faster CBD autos you'll find in this ratio class. The smell runs earthy with a soft floral edge — nothing loud, nothing that draws attention. Growers rate it easy, and it handles both indoor and outdoor setups without much fuss, so first-timers chasing a high-CBD grow don't need to overthink the environment.

Best suited for growers who want a reliable CBD-forward auto without the complexity of managing a photoperiod plant.

THC Level & Potency

Growing CBD Auto 20:1

CBD Auto 20:1 is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 8-9 weeks from seed with yields of 350-450 g/m². Plants typically reach 80-150 cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

CBD Auto 20:1 features a earthy, floral terpene profile that develops complexity throughout the flowering cycle. The complex aromatic bouquet develops fully after proper curing. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, CBD Auto 20:1 is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
