Mac1 Auto by Growers Choice Seeds

Mac1 Auto brings one of America’s most sought-after dispensary strains into a quick, easy autoflower. The original MAC comes from Alien Cookies x Miracle 15, and Growers Choice built this version on that same pairing, using Alien Cookies F2 for the Cookies side.

This balanced 50% Indica / 50% Sativa autoflower is listed at 30%+ THC, which puts it at the top end of what autos can deliver. Buds come in big, dense and coated in sticky, frosty trichomes, and depending on conditions they can develop beautiful purple hues.

Plants stay compact and bushy at 90–110 cm (35–43 in), with solid side branches and plenty of foliage. Growers Choice lists indoor yields of 550–650 g/m² (1.80–2.13 oz/ft²) and outdoor yields of 100–200 g/plant (3.5–7.1 oz/plant).

Flavor and Effects of Mac1 Auto

The aroma is complex: buttery vanilla up front, lifted by an uplifting citrus kick that keeps the creaminess from turning heavy. Under the jar lid you also catch a faint earthy, Cookies-style spice.

The taste follows the nose closely. It is smooth and creamy on the inhale, then citrus cuts in on the exhale, like orange zest grated over warm vanilla custard.

Effects kick in very quickly. Expect a strong physical stone paired with energizing, uplifting cerebral energy, a contrast that makes Mac1 feel heavy and bright at the same time. With THC above 30%, it suits times when you have nothing urgent planned.

Bag appeal matches the reputation. The dense flowers sparkle under a thick trichome layer, and phenotypes that turn purple look striking in the jar. That frost also makes Mac1 Auto an interesting option for small-batch rosin.

Growing Mac1 Auto Indoors and Outdoors

Mac1 Auto is a simple strain to grow. Growers Choice notes that it needs no training and few nutrients during the vegetative stage. Keep the lights on 18/6 or 20/4 for the full run; the plant flowers on its own and is typically ready around 11 weeks after germination.

Once bloom starts, switch to a decent bloom fertilizer to fuel the dense flowers. Because the plants are naturally bushy, a little defoliation in early flower improves light penetration and airflow, which is useful given the average mold resistance. Optional light LST can flatten the canopy, but it is not required. Cooler nights near the end can encourage purple coloring.

Indoors, Mac1 Auto fits comfortably in a standard tent, and its bushy shape fills a square meter with only a few plants, which is how growers reach the 550–650 g/m² (1.80–2.13 oz/ft²) range. Outdoors, harvests are smaller at 100–200 g (3.5–7.1 oz) per plant, but the short cycle means a sowing in late spring can be finished well before autumn rain. Either way, dry the dense buds slowly to protect the delicate vanilla-citrus terpenes.
