About Mac 3
Mac 3 is a resilient, sativa-leaning hybrid prized for its clear, uplifting head high and firm, aromatic buds. It suits growers who favour structure and predictable flowering times; with good ventilation and organic soil it develops bright citrus and diesel notes while delivering steady yields.
Mac 3 is a balanced hybrid with a clear, cerebral lean and a steady physical component. It suits users wanting clarity combined with a gentle body ease.
THC levels are typically in the low twenties, giving noticeable potency without extreme intensity. Regular users find the strength stimulating rather than overwhelming.
CBD content is low and Mac 3 is not bred for high-CBD therapy. Any CBD present simply softens the edges of the THC experience.
Mac 3 descends from Miracle Alien Cookies crossed with Alien Dawg, offering pastry and diesel characteristics. The lineage gives a stable terpene profile and consistent growth patterns.
Seeds are supplied feminised to ensure reliable flower production with few males. Growers can expect uniform phenotypes and predictable flowering schedules.
Mac 3 is best described as an intermediate grow, requiring attention to mildew and mould in humid seasons. In a wet Welsh valley climate you must prioritise airflow, drainage and canopy management to avoid rot.
Indoor flowering finishes around nine to ten weeks under stable conditions. Outdoors in southern Britain expect ripeness from late September into early October.
Yields are medium to high when plants receive consistent feeding and humidity control. Outdoor plants in a sheltered Oxfordshire garden can reward you with good harvests.
The plant has a compact, conical structure with strong lateral branching and firm main colas. Expect final heights around one to one and a half metres in favourable conditions.
Indoors, Mac 3 responds well to SCROG and SOG with careful humidity control in an Oxfordshire setup. Outdoors in Oxfordshire choose a sunny, sheltered site and protect buds from late-season damp.
Growing Mac 3 in Oxfordshire with its wet Welsh valley climate demands proactive mould management and strict canopy control. Use raised beds, free-draining compost and covers during heavy rain to protect finishing buds in Oxfordshire.
The high-THC profile brings an uplifting, cerebral head high that sharpens focus. A gentle body relaxation follows without heavy sedation.
Flavours blend bright citrus and sweet tropical notes with a diesel backbone. The smoke finishes with an earthy, slightly spicy aftertaste.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Use a balanced feed with slightly higher phosphorus and potassium during flowering and reduce nitrogen after the stretch.
Keep airflow high, space plants to open the canopy, remove dense lower foliage and act quickly on any signs of bud rot.
It is intermediate; beginners can succeed with attention to humidity control and simple training methods.
Yes — Mac 3 responds well to organic cannabis soil growing using compost, worm castings, kelp and a healthy microbial life for resilience.
Harvest when most trichomes are cloudy with a few ambers, usually late September to early October in southern England.
Aphids, spider mites and caterpillars are common; inspect regularly and use biological controls or neem oil if needed.
Provide 18/6 during veg and 12/12 for flower with suitable LED or HPS output; aim for even canopy illumination.
Topping, low-stress training and SCROG all work well to open the canopy and improve bud sites.
Dry slowly at around 18–21°C and 45–55% RH, then cure in jars, burping daily for the first two weeks to build flavour.
Keep soil pH around 6.2–6.8 to ensure nutrient availability and healthy microbial activity.
