Lemon AK Auto by Fast Buds – Citrus-Powered Autoflower with 24% THC

Lemon AK Auto by Fast Buds is a fully automatic citrus powerhouse that delivers a potent, uplifting high in under 10 weeks, perfect for growers seeking fast results without compromising on flavor or strength.

Worried your grow will be weak, slow, or tasteless?

Many autoflowering strains promise big yields and bold flavors but end up delivering bland buds, stunted plants, or inconsistent results. You invest time, space, and energy only to be left with underwhelming harvests and forgettable highs.

What if your plant never reached its full potential?

Imagine nurturing your autoflower only to watch it struggle with weak structure, poor resin production, or a dull flavor profile. Without the right genetics, you’re left with a plant that barely makes a splash — wasting your effort and killing your confidence.

Lemon AK Auto: fast, flavorful, and built to impress

Lemon AK Auto fixes that with explosive growth, sky-high THC levels (up to 24%), and a mouthwatering lemon-citrus punch. Bred from Original AK Auto and Jack Herer Auto, this sativa-dominant hybrid grows compact but powerful, producing frosty, resin-drenched colas in just 56–63 days. It’s the reliable, high-performance autoflower you’ve been waiting for.

More discretion, fewer worries

Lemon AK Auto stays compact, reaching just 0.70–1.00 m (2.30–3.28 ft), making it ideal for stealth grows in tight spaces. Its bushy, Christmas tree-like structure fills out evenly without wild stretching, so it won’t tower over your tent or draw attention. Whether you're growing indoors, in a greenhouse, or on a discreet balcony, this strain stays under the radar while maximizing yield per square foot.

Quick overview

Fast Buds’ Lemon AK Auto is a low-difficulty, high-reward autoflower. Ready in 9–10 weeks, it thrives indoors or outdoors in warm climates. Ideal for beginners and space-limited growers.

Safe start

Launch your grow with strong germination and early vigor.

• Germinate seeds in rapid rooters at 22–25 °C and high humidity.
• Transplant gently once the taproot is ~1 cm long.
• Use a light, airy soil mix with perlite for drainage.
• Consider SeedBooster Plus germination stimulator to speed up rooting and boost seedling health.

Directed growth

Guide your plant toward a strong, productive structure.

• Provide 18–20 hours of light daily using full-spectrum LEDs.
• Water when the top inch of soil feels dry — avoid overwatering.
• Use a 20L fabric pot to encourage air pruning and healthy roots.
• Apply light LST in week 2–3 to spread the canopy and improve light access.

Efficient flowering

Maximize resin and yield during the critical bloom phase.

• Reduce humidity to 40–50% to prevent mold on dense buds.
• Support heavy colas with soft ties or a trellis to prevent breakage.
• Boost bud density with SensiZym Advanced Nutrients to enhance resin production.
• Avoid high nitrogen feeds — switch to bloom-specific nutrients early.

Harvest and refinement

Nail the finish for maximum flavor and effect.

• Flush with plain water 7–10 days before harvest to improve taste.
• Harvest when 70% of trichomes are milky and 30% amber for balanced effects.
• Dry slowly at 18–22 °C and 50–60% RH for 7–10 days.
• Cure buds in glass jars for 2–4 weeks, burping daily to prevent moisture buildup.

Frequently Asked Questions

Is Lemon AK Auto good for beginners?

Yes. It’s resistant, low-maintenance, and forgiving of minor mistakes. Just avoid overwatering and aggressive pruning.

Does it smell strong during flowering?

Yes, it has a strong citrus-skunk aroma. Use a carbon filter if growing indoors to control odor.

Can I grow it outdoors in a humid climate?

Yes, but ensure excellent airflow and monitor for mold. Sativa genetics help, but humidity should stay below 60% in flowering.

How much yield can I expect in a 20L pot?

Indoors, expect 500–650 g/m². In a single 20L pot, you can harvest up to 150 g (5.29 oz) with optimal conditions.

Does it need topping or pruning?

No. As an autoflower, it doesn’t recover well from stress. Stick to LST for shaping and avoid FIM or topping.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Lemon AK Auto in my small balcony setup last summer, and it blew me away. From the first week, it showed serious vigor — dark green leaves, strong stems, and a smell that screamed 'lemon bomb.' I used a 20L fabric pot with organic soil and gave it 20 hours of light. By week 6, the main cola was the size of a pineapple, and the side branches were packed with resin. I didn’t top it — just used light LST to open the canopy. The high was perfectly balanced: uplifting, creative, and social, without anxiety. I’ve shared it with friends who said it’s one of the cleanest, most flavorful smokes they’ve had. If you want a no-fail autoflower that delivers on every level, this is it.
