From the lab panel — 28% THC, <2% CBD. From grower reports — 400-550 g/m2 yield, fruity/citrus dominant in cured flower. moderate grow.

Lineage: Zkittlez x MAC, sourced directly from NorCal Farms, gives Blue Mac a clear flavor identity before you even get to the numbers — ripe citrus, stone fruit sweetness, and a clean finish that doesn't muddy up on the exhale. At 28% THC, the effect lands firmly on the indica side: body-heavy, warm, the kind of session that ends with you not moving for a while.

Yields run 400–550 g/m² after a 9–10 week flower, which is a reasonable return for moderate-skill growers running either indoor or outdoor setups. The plants stay manageable in size, so you're not fighting canopy in a tight tent. Training helps push the upper end of that yield range, but it's not required — this one is forgiving enough to reward a clean, low-intervention grow. Best suited to growers who want high-THC indica results without navigating a difficult cultivar.

THC Level & Potency

Growing Blue Mac

Blue Mac 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 9-10 weeks with yields of 400-550 g/m2. Plants typically reach 60-100cm 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

Blue Mac features a fruity, citrus, 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, Blue Mac 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.
