MAC #4 feminized seeds deliver a high-potency photoperiod hybrid with THC levels consistently testing between 27% and 30%, placing this strain firmly in the upper tier of contemporary cultivars. Dense, resin-coated buds with a striking pale green and amber trichome structure make it as visually distinctive as it is chemically potent. Built for growers who want reliable feminized genetics without sacrificing complexity in the final product.
Genetics & Lineage
MAC #4 is a phenotype selection from the MAC (Miracle Alien Cookies) lineage, which traces back to a cross of Alien Cookies F2 with a Columbian and Starfighter hybrid. MAC was originally bred by Capulator, and MAC #4 represents one of the most stable and resin-forward phenotypic expressions of that line. The genetic ratio sits at roughly 50% indica and 50% sativa, inheriting the cerebral clarity of its sativa side and the dense bud structure and heavy trichome production typical of its indica heritage. Feminized production ensures that nearly all plants under standard photoperiod conditions will flower as females.
Aroma, Flavour & Effects
The terpene profile is dominated by caryophyllene, limonene, and myrcene, which together produce a sharp citrus-forward aroma undercut by diesel fuel and damp earth. On the exhale, the flavour softens into a creamy, slightly floral finish that offsets the more aggressive diesel notes on the intake. Effects onset within minutes of consumption and begin with a pronounced cerebral uplift — focused and clear-headed rather than racey. As the session progresses, the indica genetics introduce a body relaxation that is substantial but not sedating at moderate doses. At higher doses, the 27–30% THC content will be noticeably heavy for less experienced consumers, making portion awareness important.
Growing Profile
MAC #4 performs well both indoors and outdoors, with indoor cultivation offering the most control over the final product. Under a 12/12 light cycle indoors, flowering completes in approximately 63 to 70 days. Indoor yields average around 450 to 550 grams per square metre under optimised conditions, including adequate airflow to manage the dense canopy this strain produces. Outdoors, plants can reach 150 to 180 cm and are typically ready for harvest in early to mid-October in the Northern Hemisphere, with outdoor yields ranging from 500 to 600 grams per plant in favourable conditions. The thick bud structure and heavy resin production make this strain moderately susceptible to humidity-related issues during late flower, so maintaining relative humidity below 45% in the final two to three weeks is strongly recommended. MAC #4 responds well to low-stress training techniques such as LST and SCROG setups, which help distribute light evenly across the canopy and maximise bud site development. Difficulty is rated moderate — manageable for attentive beginners but most rewarding in the hands of growers with at least one or two previous grows.
Who This Strain Is For
MAC #4 suits consumers who prioritise potency and terpene complexity in equal measure, particularly those with a preference for citrus-diesel flavour profiles. Medically, the balanced hybrid effects have appeal for those managing stress, mood disorders, or mild to moderate chronic pain without wanting full sedation. For growers, it fits well in both tent setups and larger indoor rooms, and rewards those willing to invest in humidity management and canopy control. Outdoor cultivators in temperate climates with warm, dry autumns will find the yield-to-effort ratio particularly strong.
MAC #4 feminized seeds represent a well-documented, high-resin hybrid that consistently delivers on both potency and flavour when given attentive cultivation conditions.
