Spec sheet first — strain: indica, seed type: feminized, THC: 20-25%, yield band: medium, environment: indoor or outdoor.

Smell-first: cut a Mac Rillaz F1 bud open and the room fills with something between tangerine peel and a gas station—citrus up front, diesel underneath, a little sweetness at the back of your throat. That aroma carries straight into the effect: 20–25% THC that settles into the body without putting you horizontal, which makes it more useful across an evening than a hard sedative indica. Blimburn Seeds built this feminized F1 to pull 400–500 g/m² in 8–10 weeks of flower, indoors or out, so it fits a BC or Ontario outdoor season with room to spare before frost. Plants stay manageable in height, and the moderate difficulty rating is honest—she'll respond well to basic topping and a consistent feed schedule, but she won't punish a small mistake.

Best suited to growers with one or two runs under their belt who want a reliable yielder without babysitting a finicky phenotype.

THC Level & Potency

Mac Rillaz F1 delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable.

Growing Mac Rillaz F1

Mac Rillaz F1 is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm 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 40-50% 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

Mac Rillaz F1 features a fruity, citrus, diesel, sweet terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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, Mac Rillaz F1 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.
