Typical mistakes this product helps you avoid

Auto Return of the Mac’s predictable growth reduces common pitfalls, especially for new growers.

• Over-pruning: Avoid heavy topping—autos don’t recover well. Light LST only.
• Late transplanting: Plant directly in final pot (18–27 L / 4.76–7.13 gal) to avoid shock.
• Overfeeding: Start with ¼ strength nutrients—autos are sensitive to excess salts.
• Poor airflow: Keep RH below 50% in flower to prevent mold on dense buds.
• Ignoring trichomes: Harvest at 70% milky/30% amber for balanced effect.

Frequently Asked Questions

Can I grow Auto Return of the Mac outdoors in a cold climate?

It’s best suited for temperate or warm climates. If your summer averages stay above 18°C (64°F), it can thrive. In colder zones, grow in a greenhouse or large pot you can move indoors at night.

Do I need to use nutrients with this auto?

Yes, but start light. Use a balanced veg formula at 25% strength for the first 3 weeks, then switch to bloom nutrients by week 4. A gentle booster like B´CUZZ ROOT STIMULATOR helps build a strong foundation without burning.

How many seeds should I plant for a full harvest?

For indoor SOG, 9–12 plants per m² (1 plant per sq ft) in 11 L pots works well. Outdoors, 1–2 plants in 25 L pots can yield over 80 g each if given full sun and proper feeding.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown Auto Return of the Mac three times now—once for a friend who just wanted something easy, and twice for my own stash. For beginners, I tell them: “Just give it light, water when the top 2 cm (0.79 in) is dry, and don’t touch the top.” It’s that simple. My friend got 45 g from a single plant in a 20 L pot on a sunny balcony—more than enough for a month.

For myself, I ran it in a 1 m² tent with 6 plants in 18 L pots under LED. I used light LST to open the canopy and fed with a mild organic schedule. By week 7, the smell was intense—sweet lemon and fuel. I harvested at 9 weeks with 480 g/m² of frosty, dense buds. The high is clean and energizing—perfect for creative work or social hangs. It’s now one of my go-to autos for fast, reliable results. Just remember: no aggressive pruning, and flush well before harvest for the cleanest smoke.
