Original Auto Amnesia Haze by FastBuds – XXL Sativa-Dominant Autoflower with Citrus Haze Flavor

Original Auto Amnesia Haze by FastBuds is a towering sativa-dominant autoflower that delivers massive yields and a classic Haze high in just 10 weeks, making it perfect for growers who want big, potent harvests without the wait.

Are you tired of small, underwhelming autoflowers that barely fill a grinder?

Most autos cap out at medium yields and mild effects — but if you're chasing that legendary Haze rush, those just won’t cut it. You need power, height, and flavor, not compromise.

What happens when you settle for weak, short strains?

You end up with lackluster highs, tiny harvests, and the frustration of growing three plants just to get one decent session. You waste space, time, and nutrients on underperformers that don’t deliver the cerebral punch or aromatic depth you’re after. And when you’re investing in lights, soil, and effort, that’s a serious ROI loss.

Original Auto Amnesia Haze is the high-flying solution for serious sativa lovers

This isn’t your average auto — it’s a 70% sativa powerhouse that stretches up to 1.50 m (4.92 ft) and floods your space with citrus-tinged Haze aroma. With up to 650 g/m² (22.9 oz/ft²) indoors and dense, resin-coated buds, it turns your grow into a high-yield, high-thrill experience. It’s the rare auto that acts like a photoperiod, giving you massive returns without the long wait.

What this strain brings to your grow: space, flavor, and serious potency

Original Auto Amnesia Haze transforms your setup into a sativa sanctuary. Whether you’re growing solo in a tent or running a SOG, this strain dominates with vigor and presence. You’ll get a soaring, creative high that lasts for hours — perfect for daytime sessions, creative work, or social hangs. The flavor is pure old-school Haze: sharp citrus on the inhale, deep floral notes on the exhale, and a long, clean finish. It’s not just a smoke — it’s a full sensory experience.

Pro tips to maximize your harvest without overspending

Start this strain in its final pot — 20–27 L — to avoid transplant stress and support its rapid growth. Use low-stress training (LST) early to control height and expose more bud sites. Avoid topping or aggressive pruning, as autos don’t recover well. Feed moderately — this isn’t a heavy feeder, so stick to standard nutrient schedules. In late flowering, reduce humidity to prevent mold, especially in dense colas. For best flavor, flush 10–14 days before harvest and cure slowly at 60% RH.

Safe start: Germinate in a moist, dark environment at 22–25 °C. Transplant carefully when the taproot is 1–2 cm long. For a stronger start, Bio Grow by BioBizz boosts root development and reduces shock.

Directed growth: Use 18–20 hours of light daily. Grow in 20–27 L pots with well-aerated soil. Apply B’Cuzz Soil A+B by Atami for balanced nutrition that supports vigorous growth without nutrient burn.

Efficient flowering: Maintain RH at 40–50% to prevent mold. Support heavy colas with stakes. Add Super PK by Aptus in week 3 of flowering to boost resin and bud density.

Harvest and refinement: Harvest when trichomes are mostly milky with some amber for a balanced high. Flush 10–14 days before harvest. Dry at 18–22 °C and 50–60% RH, then cure for 3–4 weeks in glass jars.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Original Auto Amnesia Haze last summer in my greenhouse, and damn — this thing is a beast. At 1.45 m (4.76 ft), it towered over my other autos, with colas so dense they needed bamboo support. I ran LST from week 3, which helped spread the canopy and maximize light exposure. I used a simple soil mix with Top Crop Complete Mix and fed lightly — she doesn’t need much. The high hit hard: first energizing and creative, then smoothly mellowing into a relaxed, philosophical vibe. Perfect for afternoon sessions. The citrus-floral aroma filled the greenhouse. My only tip? Watch the humidity — I lost some bud to mold in a wet spell. Otherwise, one of the most rewarding autos I’ve grown. If you’ve got the space and experience, don’t sleep on this Haze legend.
