Most autoflowers lean on compact indica genetics, which is exactly why a true Haze auto is so hard to find. Xtreme Haze Auto breaks that pattern. Dutch Passion spent two years refining this line around its classic Outlaw Amnesia (Amnesia x Super Haze), and the result is a sativa-dominant autoflower that grows, smells and smokes like a real Haze while still running on its own internal clock.
There is no need to flip the lights. These feminized seeds switch to bloom by themselves, so you can keep a single 18/6 or 20/4 schedule from sprout to chop and harvest roughly 11-12 weeks after germination (about 80 days on average). Compared with photoperiod Hazes that can sit in flower for 12-15 weeks after veg, that is a serious shortcut.
Plants usually settle around 100-125 cm (39-49 in), though the range runs from 75 cm (30 in) in small pots to roughly 150 cm (59 in) under powerful lighting. Indoors, Dutch Passion puts the typical harvest at around 500 g/m² (1.64 oz/ft²), with skilled growers pushing past 600 g/m² (1.97 oz/ft²). Single plants range from 50-100 g (1.8-3.5 oz) for first-timers to 200-500 g (7.1-17.6 oz) in expert hands.
The structure is the familiar Dutch Passion auto layout: one dominant main cola surrounded by large, productive side branches, all of them swelling with long, compact flowers that get noticeably heavy in the final weeks.
Aroma, Flavor, and a Proper Haze High
Open the tent in mid-bloom and the first impression is unmistakable Haze: spicy, incense-like and sharp, with lime zest, cool menthol and a floral skunk note woven underneath. Fans of Silver Haze, Mexican Haze or Super Silver Haze will recognize the family resemblance immediately. The aroma is loud and penetrating, so plan your carbon filtration accordingly.
On the palate the buds swing between a Haze-forward spice and a softer, herbal skunk, depending on phenotype. A sour citrus thread runs through all of them, and the smoke is smooth when the flowers are dried slowly and cured with care. Even fresh off the drying line the terpene profile is impressive.
The effect arrives quickly. This is not a creeper: a couple of pulls deliver a clear, energetic and euphoric head rush that keeps you upright and engaged rather than sinking into the couch. A small indica contribution in the background adds a little weight without dulling the buzz, and the high stays with you for hours before mellowing out.
Think of it as a daytime Haze for creative work, long walks or social afternoons. Take a heavier dose late in the evening and the experience turns calmer and more laid-back.
Growing Xtreme Haze Auto
This is one of the few autoflowers that genuinely suits a SCROG. Vigorous lateral growth fills a net fast, while bending, supercropping or cropping keeps the canopy level if headroom is tight. Left untrained she forms a full Christmas tree shape that is equally productive.
Give her room to root: 15 L (4 gal) is a sensible minimum, and containers up to 50 L (13 gal) are welcome, especially outdoors in hot climates where 40-50 L (10.5-13 gal) provides a bigger moisture buffer. Fabric pots or air-pruning containers keep oxygen high, which matters because she dislikes waterlogged roots.
She handles warm grow rooms better than most autos and loves intense light. In late bloom, add stakes or a net to support sagging colas and keep humidity low with steady airflow. Outdoors, plant during the three warmest summer months for the cleanest finish.

FAQ
Is Xtreme Haze Auto a true Haze?
Yes. It descends from Dutch Passion’s Outlaw Amnesia, an Amnesia x Super Haze cross, and it keeps the spicy, citrus-laced Haze aroma and the clear, energetic high that Haze lovers look for, only in autoflowering form.
How long does Xtreme Haze Auto take from seed to harvest?
Expect about 11-12 weeks, roughly 80 days after germination. That is slightly longer than most indica autos, but quick for a sativa-dominant Haze.
How tall does Xtreme Haze Auto grow?
Most plants reach 100-125 cm (39-49 in). Small pots can keep her near 75 cm (30 in), while large containers and strong lighting can push her toward 150 cm (59 in).
What yield can I expect indoors?
Dutch Passion lists around 500 g/m² (1.64 oz/ft²) indoors, with experienced growers reaching 600 g/m² (1.97 oz/ft²) or more. Individual plants range from 50-100 g (1.8-3.5 oz) to 200-500 g (7.1-17.6 oz) depending on skill and setup.
Can I grow Xtreme Haze Auto in a SCROG?
Yes. Her stretch and vigorous side branching make her one of the few autos that fill a SCROG net well. Supercropping and bending also help manage height.
What light schedule should I use?
As an autoflower she does not need a 12/12 switch. Run 18/6 or 20/4 for the whole cycle and give her as much light intensity as your setup allows.
