Strain Overview

Lineage: Zweet Inzanity x Durban Auto (Proprietary Auto Donor)
Market Status: The "Daytime Driver"; Zweet Auto is a rarity in the autoflower market—a true, high-energy Sativa that doesn't sacrifice yield or potency. It was bred to capture the electric, racy high of the famous Zweet Inzanity and package it into a fast-finishing automatic format. It is known for its aggressive vigor, growing larger than most autos, and its piercing terpene profile of sour lime candy and chemical gas. It is a favorite for morning smokers and outdoor growers looking for a massive harvest before the frost.
THC Content: High (20% – 25%)
Dominant Terpenes: Terpinolene, Limonene, Ocimene, Myrcene
Key Effects: High Energy, Clear Focus, Racy Euphoria, Appetite Suppression (Variable)
Zweet Auto is like biting into a sour lime.
It wakes you up immediately. It abandons the heavy, earthy notes of traditional autos and leans entirely into the sharp, acidic side of the spectrum. It smells of sugary lime zest, chemical cleaner, and fresh pine. It is a loud, unapologetic plant that offers a "coffee-like" buzz perfect for getting through a busy day.
History and Lineage: The Sativa Conversion
This strain is the result of taking a massive photoperiod Sativa and successfully converting it to an autoflower without losing the "Sativa" spirit.
The Mother (Zweet Inzanity): The beast. A cross of Zweet OG x Durban Poison, this strain is legendary for its uncontrollable vigor, massive yields, and sour candy terpenes. It is arguably one of the strongest growing plants in the Ethos lineup.
The Father (Durban Auto): The timer. By using a selected Durban Poison Autoflower as the donor, Ethos reinforced the Sativa traits (height, energy, terpinolene) while introducing the automatic flowering gene.
The Synthesis: Zweet Auto is a "Super Auto." It grows with the structure and size of a photoperiod plant but flowers automatically. It retains the signature "Zweet" flavor—a mix of sour citrus and chem—and the soaring, no-ceiling high.
Terpene Profile: Sour Lime and Turpentine
The aroma of Zweet Auto is volatile and sharp. It is dominated by "High Pitch" terpenes that clear the sinuses.
Dominant Terpenes
Terpinolene (The Haze): The dominant terpene. It provides the signature turpentine, green apple, and floral lime aroma. It is responsible for the "racy" heart-pumping effect.
Limonene (The Citrus): Adds a sharp lemon/lime zest note. It smells like sour candy powder.
Ocimene (The Sweetness): A rare terpene that adds a woody, herbal sweetness, balancing the chemical harshness of the Terpinolene.
Myrcene (The Fruit): Present in lower amounts, adding a background hint of sweet mango that prevents the smoke from being too astringent.
Flavor Notes:
The Aroma: It is piercing. It smells of sour lime candy, turpentine, pine-sol, and gasoline.
The Smoke: Sharp and expansive. It tastes of zesty lime and chemical earth on the inhale, with a spicy haze finish on the exhale.
Strain Effects: The Morning Jolt
Zweet Auto is strictly a daytime strain. Consuming this at night is a recipe for staring at the ceiling.
The Experience
The Rush: The high hits instantly with a jolt of mental energy. Fog clears, and thoughts accelerate. It can be slightly disorienting for low-tolerance users.
The Focus: Once the initial rush settles, it creates a hyper-focused state. It is excellent for cleaning, exercising, or outdoor activities like hiking.
The Mood: It is euphoric and uplifting. It is a great "antidote" for a sluggish morning or a mid-day crash.
The Body: There is very little body load. You feel light on your feet. There is no couch lock.
Best For: Wake-and-bake, gym sessions, hiking, creative work, and battling fatigue.
Growing Zweet Auto: The Green Giant
Do not treat this like a small autoflower. It has the potential to take over a tent.
Growth Structure
The Size: Large. This is an "XL" autoflower. It can easily reach 4 to 5 feet in height. It stretches significantly when it begins to flower (around day 35-40).
The Yield: Very High. It produces long, Sativa spears rather than dense golf balls. It is one of the highest-yielding autos available.
The Structure: Open and lanky. It has long internodes, allowing light to penetrate deep into the plant.
The Feeding: Moderate to Heavy. It grows so fast that it needs plenty of fuel. Keep Nitrogen levels steady through the stretch.
The Time: It takes longer than average autos, finishing in 80 to 90 days from seed. The extra time is needed for the Sativa buds to swell.
Grower’s Tip: Support is mandatory. The branches are long and can be spindly (Sativa trait). As the heavy colas develop, they will flop over without bamboo stakes or a trellis net. Also, be prepared for the stretch—ensure you have enough vertical headroom.
Similar Strains / Lineage Relations
If you enjoy the profile or growth of Zweet Auto, you might also appreciate these three genetically related or similar strains:
Zweet Inzanity: The Mother.
Why: If you have the space for a massive photoperiod plant and want to clone the genetics, go for the original. It offers even higher yields and potency than the auto version.
Durban Poison: The Ancestor.
Why: This is the grandfather of the line. If you want the purest "Racy" Sativa experience with a distinct anise/licorice and lemon profile, Durban Poison is the classic choice.
Super Lemon Haze Auto: The Competitor.
Why: If you are looking for a citrus-forward Sativa auto but find the Zweet/Chem profile too harsh, Super Lemon Haze offers a sweeter, more floral lemon experience with similar energetic effects.
Final Verdict: The Sour Sativa Speedster
Zweet Auto is a performance plant. It breaks the myth that autoflowers are small, low-potency plants. It grows like a tree, smells like a lime factory, and hits like a double espresso. It is the perfect strain for the grower who wants a massive harvest of daytime smoke without the hassle of a 12/12 light cycle.
You should choose Zweet Auto if:
You love Sour/Lime/Chem flavors.
You want a High-Energy Sativa.
You have plenty of vertical space.
You want Maximum Auto Yields.
Score: 9.5/10 (The XL Sativa Auto)
