Week by week

Germination: Days 1–7

Pop the seed.

Soak in a moist paper towel or plant 1cm deep in light, airy soil.
Keep warm (22–25°C), humid and dark until the sprout appears.
Moist, never soggy.

Seedling: Weeks 2–3

First true leaves.

Gentle light on 18/6, high humidity (~65%).
Tiny waterings near the stem; let the top dry between.
Quarter-strength nutrients at most.

Vegetative: Weeks 4–6 (auto)

Build the plant.

Autoflowers veg briefly then flower on their own, start in the final pot, don't transplant late.
Feed grow (high-N) nutrients; train (LST/topping) for an even canopy.
Hybrid structure, balance height and bush with light training.

Flowering: ~6–8 weeks of bloom

Buds bulk up.

Stays on 18/6 to harvest.
Switch to bloom (high-P/K) nutrients; lower humidity (~45%) to prevent bud rot.
Watch trichomes: mostly cloudy with some amber = peak ripeness.

Flush & harvest: Final 1–2 weeks

Finish clean.

Plain water (no nutrients) the last 1–2 weeks for a smoother smoke.
Harvest, wet-trim, dry slowly (~60°F / 60% RH, 7–14 days).
Cure in jars 2+ weeks, burping daily at first.

~10–12 weeks seed to harvest.

Growing Auto Mac #1 outdoors

Sown outdoors in mid May, after the last frost, Auto Mac #1 should be ready in late July to early August. That leaves time for a second run: a seed sown by early July finishes around mid to late September.

Drying and curing

Its berry and sweet notes come from the most volatile terpenes, the first to go in a warm, fast dry. Dry slowly around 18 °C and 60% humidity for 10 to 14 days and cure in jars to keep them.
