Seedsman runs this as a hybrid autoflower line — 18-25% THC lab range, sweet/earthy-dominant terps, 9-11 weeks total from flip.

Eight growers logged this one as a low-maintenance autoflower that still punches above its weight — 18–25% THC from a strain that finishes seed to harvest in 9–11 weeks without much fuss. Radical Juice Auto runs well indoors or out, making it a reasonable pick for Canadian growers who want a short-season plant that can wrap up before the cold sets in.

Yields land between 400–550 g/m² under good light, which is solid for an autoflower rated easy difficulty. The flavor profile leans sweet with an earthy backbone — nothing polarizing, nothing that'll chase off guests. It's not the most complex nose on the shelf, but it's consistent and approachable. Seedsman's catalog is deep, and this one sits in the middle of it as a workhorse rather than a showpiece. Good fit for newer growers looking for a forgiving auto that doesn't require dialing in a complicated feed schedule to hit respectable numbers.

Effects & Experience

Users report primarily euphoric and relaxed effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Radical Juice Auto delivers THC levels of 18-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Radical Juice Auto

Radical Juice Auto 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 9-11 weeks total with yields of 400-550g/m². Plants typically reach 60-120cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Radical Juice Auto features a sweet, earthy terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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, Radical Juice Auto 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.
