Product detailed description

Advantages of autoflowering genetics and benefits for growers

Looking for maximum speed, highly self-sufficient plants and outstanding yield potential without the need to change the light cycle? MAC Dawg XXL Auto is a modern autoflowering annual plant that combines the elite American genetics Chemdawg Bx1 and MAC Auto. It offers exceptional vitality and production power that can easily compete with classic photoperiod varieties.

The main advantage of this autoflowering variety is its high genetic stability and natural resistance to common growing mistakes. Thanks to its undemanding nature and balanced growth, it is a perfect choice for beginners and experienced growers who require a fast and reliable harvest.

Life cycle and dynamic development from seed to harvest

The complete life cycle of this annual plant takes just 58 to 63 days (approximately 8 to 9 weeks) from germination. During the first 20 days, the plant displays explosive vegetative growth, rapidly developing a strong root system and an extensive canopy ready for flower formation.

The plant develops a compact, bushy structure with short to medium internodal spacing and characteristic serrated leaves. The dense canopy makes efficient use of incoming light, ensuring even development of flower sites along the entire length of the branches.

Morphology, yield and technical growing parameters

When grown indoors under an 18/6 or 20/4 light cycle, it produces a yield of 550 to 650 g/m2. Outdoors, it reaches a very practical height of 1.2 to 1.4 metres and, with plenty of sunlight, offers a yield of 100 to 400 g per plant. Depending on the sowing date, the outdoor harvest can take place continuously from the end of June to the end of October.

The flowers mature to an exceptional density and are literally covered in a sticky layer of resinous trichomes, which also extends to the surrounding leaves. For optimum results, we recommend growing the plant in a light, aerated substrate with good drainage.

Pungent and dense terpene profile

The aromatic expression of this variety is complex, intense and unmistakable. It is dominated by heavy notes of raw diesel and kerosene combined with the earthy foundation of the Kush line. This fuel-like composition is harmoniously complemented by fresh pine needles, cedarwood, citrus peel and a touch of hot spice.
