Pineapple Express Auto FastBuds – Tropical Autoflowering Strain with Balanced High & High Yield

Pineapple Express Auto by FastBuds is a high-performing, easy-to-grow autoflowering strain that packs a punch in flavor, yield, and effect — all in a 10-week cycle.

Are you tired of weak, flavorless autoflowers that barely cover your costs?

Most autoflowering strains promise big but deliver small — low yields, bland taste, and forgettable effects. You end up wasting time, space, and nutrients on plants that don’t reward your effort.

What happens if you keep settling for underperforming genetics?

You’ll stay stuck with mediocre harvests, weak highs, and the constant frustration of plants that stretch too much or collapse under their own weight. You’ll miss out on the tropical terpene explosion and balanced buzz that makes cannabis truly enjoyable. And worst of all? You’ll doubt your skills — when the problem isn’t you, it’s the seed.

The solution? Pineapple Express Auto — a powerhouse that grows like a Christmas tree and rewards like a champion

With Pineapple Express Auto, you get a stable, vigorous plant that delivers up to 550 g/m² indoors and massive 2–7 oz/plant outdoors. It grows tall — up to 1.40 m (4.59 ft) — with dense, resin-coated buds that smell like a pineapple smoothie. The high is perfectly balanced: uplifting and creative, yet calm and clear. No anxiety, no couch-lock — just pure, flavorful satisfaction.

Enjoy a tropical flavor experience in every puff

From the first whiff to the final exhale, Pineapple Express Auto treats your senses. The buds burst with sweet, tropical notes and a tangy sour pineapple kick that lingers on the palate. It’s not just tasty — it’s memorable. Whether you’re sharing with friends or savoring solo, this strain turns every session into a mini-vacation.

How to grow Pineapple Express Auto for maximum results

Start strong and finish stronger. This autoflower thrives when given space and stability from day one.

1. Germinate seeds in a moist paper towel or directly in a light, airy substrate like Juju Royal Substrate.
2. Transplant to a final pot of 18–27 L early — this plant grows big and needs room to stretch.
3. Provide 18–20 hours of light daily; no photoperiod switching needed.
4. Use low-stress training (LST) to control height and boost bud sites — avoid topping.
5. Monitor pH around 6.5 and feed steadily; this strain loves nutrients, especially in coco.
6. Watch for humidity in late flowering — keep RH below 50% to prevent mold, especially in dense colas.
7. Harvest around week 10 when trichomes turn milky to amber for a balanced effect.

Care, maintenance and storage

Keep your Pineapple Express Auto healthy by maintaining proper airflow and avoiding overwatering. Flush with plain water 7–10 days before harvest to improve taste and smoothness. After cutting, dry slowly at 18–22 °C (64–72 °F) and 50–60% RH for 10–14 days. Cure in glass jars for 2–4 weeks, opening daily at first to release moisture. Store cured buds in airtight containers away from light and heat to preserve terpenes and potency.

Frequently Asked Questions

How long does Pineapple Express Auto take from seed to harvest?

The full cycle lasts about 10 weeks from germination to harvest, making it a fast and reliable choice for quick turnover.

Is Pineapple Express Auto good for beginners?

Yes, it’s very beginner-friendly — stable, forgiving, and resistant to common growing issues when basic conditions are met.

Can I grow this strain outdoors in a humid climate?

Yes, but be cautious during late flowering. Ensure good airflow and consider using Proactive BAC to boost microbial defense against mold.

What size pot should I use for Pineapple Express Auto?

Use a final pot of 18–27 L to allow full development. Larger pots support bigger plants and higher yields.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Pineapple Express Auto in my 1.2 x 1.2 m tent under a 600W LED. I used 25L pots and a coco-coir mix with Advanced Nutrients Cultivator Series. I started LST early and kept RH around 50%. By week 8, the smell was insane — like opening a can of tropical juice. At harvest, I got 512 g/m² of dense, sticky buds. The high is smooth and motivating — I use it for writing and music. It’s not the absolute highest yielder, but the flavor and ease make it a top-tier auto. My only tip? Don’t rush the cure — let those terps shine.
