Auto Red Poison by Sweet Seeds is a fast, high-yielding autoflower that delivers dense, aromatic buds in just 8 weeks from germination, making it a top choice for growers who want quality and speed without compromise.
Still stuck with slow, unpredictable grows that leave you waiting weeks longer than expected? You’re not alone. Many growers waste time and space on strains that stretch too much, yield little, or fail to deliver on flavor and effect. The result? Frustration, wasted resources, and mediocre harvests that don’t live up to the hype.
That cycle ends with Auto Red Poison. This autoflowering powerhouse combines the legendary Green Poison® with a rare Pakistani Kush Auto lineage to give you a plant that grows fast, finishes early, and rewards you with thick, resin-coated buds bursting with sweet, fruity flavor and a soft Skunk finish. It’s not just fast—it’s flavorful, potent, and built to perform in any setup.
What It Feels Like to Grow and Taste Auto Red Poison
From the first sprout to harvest, Auto Red Poison feels like a pro move—even if you’re just starting out. The plant shows strong hybrid vigor early, developing a sturdy main stem and flexible side branches that handle training with ease. Indoors or out, it stays manageable at 0.60–1.20 m (1.97–3.94 ft), making it perfect for small spaces or stealth grows.
When cured, the buds release a rich, sweet aroma with fruity notes and a subtle Skunk background that lingers in the air. The flavor is smooth and enjoyable, never harsh. Effects are deeply relaxing with a spark of creativity—ideal for unwinding after work or sparking inspiration during a chill evening.
How to Maximize Your Auto Red Poison Harvest
Get the most out of every seed with these pro tips:
- Start in the final pot (18–27 L) to avoid transplant stress
- Use 18–20 hours of light daily throughout the entire cycle
- Keep humidity at 50–60% in veg, dropping to 40–50% in flowering
- Support heavy colas with soft ties or trellis netting
- Harvest when trichomes turn milky to amber for balanced effects
- Flush 7–10 days before harvest for a cleaner, smoother smoke
- Pair with HESI Bloom Complex for Soil to boost resin and flower density
Why Auto Red Poison Fits Perfectly in Your Grow Setup
This strain plays well with others—literally. Its compact size and short cycle make it ideal for blending into mixed grows or using alongside other autoflowering strains. It thrives in soil, coco, or hydro, and responds well to organic inputs like guano or mycorrhizae. Whether you’re running a simple SOG or a full SCROG, Auto Red Poison adapts and delivers.

How to Grow Auto Red Poison Successfully
Auto Red Poison is beginner-friendly but rewards attention to detail. Here’s how to grow it right:
Quick overview: Sweet Seeds autoflower · 8-week cycle · low difficulty · ideal for indoor, outdoor, or balcony grows.
Safe start: Germinate in a moist, dark environment at 22–25 °C. Transplant gently when the taproot is ~1 cm long. For a faster start, Seedbox Plagron boosts root development and reduces shock.
Stable seedling: Keep humidity high (60–70%) and light gentle. Water lightly and ensure good drainage. Adding Mykos Root Paks supercharges root health and nutrient uptake from day one.
Directed growth: Maintain 18–20 hours of light. Use airy soil and avoid overwatering. LST works well early on—just don’t top or FIM, as autos don’t recover well.
Efficient flowering: Lower humidity to 40–50%. Support heavy buds and monitor trichomes. At peak bloom, Top Max BioBizz enhances resin and aroma.
Harvest and refinement: Harvest when 70% of trichomes are milky, 30% amber for balanced effects. Dry at 18–22 °C and 50–60% RH. Cure in jars for 2–4 weeks, burping daily.

Personal Experience of Pevgrow’s CEO (Alan)
I’ve grown Auto Red Poison three times now—twice indoors under LEDs, once outdoors in Mediterranean summer. Every time, it’s been a standout. The first thing you notice is how fast it moves. By week 3, it’s already showing pre-flowers. By week 5, the smell is unmistakable—sweet, fruity, with that classic Skunk punch.
What really impresses me is the consistency. All three plants developed purple hues, and the resin production was insane—sticky as hell, perfect for hand-rolling or extracts. I didn’t top them, just used light LST to spread the canopy. Yield was solid: 520 g/m² indoors, 140 g/plant outdoors.
My pro tip? Don’t rush the cure. Let it go 3 full weeks in the jar. The flavor smooths out, the high becomes richer, and suddenly you understand why this one keeps winning awards. It’s not just a grow—it’s a vibe.

Customer reviews Auto Red Poison
Is in early stages of vegetation but looking great
Really good quality seeds. I would definitely buy it again and recommend to others just.
I had 2 of these genetics, and I can say that the best flavor and color that I have seen personally, I got on average 1 bottle per plant, it is not much production but for an autoflowering quite well, I always recommend this auto gene, surprise its aroma and colors, it is beautiful!
I grew it outdoors and one of the ones that I liked the most in its extraordinary growth and taste. Powerful effects, a lot for my taste, and incredible aroma. He didn't always grow it because I like the variety, but if I had to choose a fixed one in my plantation it would be this one.
Culture 400w hps 1x1m2 in 7 l 16 specimens of red poison auto. Very homogeneous, I would say that as for "reds" or purple plants, it is the most stable I have tried, all the specimens of the same size and resin. A very pleasant taste of red fruits and earthy smell, low production, about 10 grams per plant, but quite fast, in about 3 months can be harvested. Finally I would say that all the varieties of this bank that I have tested are quite stable and worked genetics. Recommended 100% for beginners or anyone looking for a decent "network".
I grew outdoors in the sun most of the day ,without manipulation or transplants,6 flowerpots of cloth,without just a little fertilizer, just a little bit of very soft pk in the mixture, because i used a soil with earthworm humus and would take out about 70 g with a smell and taste of berries with a citric touch at the end.
interior with a sodium 400 wts cooler air inlet and outlet, I controlled P.H. and Humidity, in 65 days gave me 20 grams, not very tasty because I did not wash roots, but effective
An indoor crop, very good stock, a beautiful crop. Full of strong colors, rich flavor, it doesn't make you want to cut the after after jajaja sensational experience!
Outdoor cultivation in a 7l smart pot in my balcony. I really liked watching her grow and pick up that characteristic red color.
Hello, I put two red poison of sweet seeds in it, a little purple and a little red poison, it tastes very good and it's very good... I was surprised, for how small it is.... That if with a good root washing hahaha
It was in a 7L pot from the beginning.
It was an indoor crop, quite curious because I proceeded to put only 2 seeds, as I was told with a space of 80x80x1'80 with 2 I could get a good yield with an apical pruning, I had them almost 3 weeks in growth and 2 months and 1 week, with a focus of 220W and I got a total of 175g prox. of each one, a total of almost 400, a unique aroma and flavor, apart from the hehehe buzz, undoubtedly at the end one of my favorites.
I carried out an outdoor cultivation, started in May, on a terrace, using a substrate preparation with peat, worm humus and guano. I got incense-flavored, red-white-purple plants. With a production of 65g approx. per plant. After a cure of 1 month it reached its maximum potency, both in taste and smell. From then on, it decreased in taste and smell, opening the jar every 3 days to air until I got tired of opening and closing, and it remained as much in smell as it was in taste and power.
