How to grow Auto Afghan Mass XXL

Auto Afghan Mass XXL is a low-maintenance powerhouse, perfect for both new and experienced growers. Here’s how to get the most out of it.

Quick overview: Autoflowering · 00 Seeds · 75–80 day cycle · Low difficulty · Ideal for indoor tents or outdoor gardens.

Safe start: Germinate in a moist, dark environment at 22–25 °C. Transplant once the taproot is ~1 cm long. For a stronger start, Seedmaker boosts root development and reduces shock.

Stable seedling: Keep humidity at 60–70% and light intensity moderate. Water lightly and ensure good drainage. A healthy root zone means faster growth—Bactomatik Rex supports microbial life and prevents root rot.

Directed growth: Use 18–20 hours of light daily. Opt for well-aerated soil or coco. Apply LST early to open up the canopy. Avoid topping—autos don’t recover well from stress.

Efficient flowering: Reduce humidity to 40–50% to prevent mold. Support heavy colas with stakes if needed. At peak bloom, PK 13/14 enhances resin and bud density.

Harvest and refinement: Harvest when trichomes are mostly milky with some amber for a sedative effect. Flush 7–10 days before harvest. Dry at 18–22 °C and 50–60% RH, then cure for 2–4 weeks to maximize flavor.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Auto Afghan Mass XXL in my 1.20 x 1.20 m (3.94 x 3.94 ft) tent under a 600W LED. Planted five seeds in 20L pots, straight into Plagron Royal Mix. I kept it simple: 18/6 light cycle, light watering at first, then increased as it grew. No topping, just light LST in week 3 to spread the canopy. By week 6, the smell was intense—earthy, spicy, impossible to miss. I used a carbon filter, and it helped. At day 78, trichomes were milky with a hint of amber. I flushed for 10 days, dried slowly, and cured for three weeks. The buds were rock-hard, covered in crystals, and the high was deep and lasting. One of the best indica-dominant autos I’ve grown. I’ll definitely be growing it again—maybe even outdoors next time.
