Super Magnum Auto: The Breeding Backbone

Super Magnum Auto: The Breeding Backbone

Super Magnum Auto Strain Review

Strain Overview

  • Type: Sativa-Dominant Autoflower (Hybridized with Ruderalis)

  • Breeder: Barney’s Farm (Proprietary Selection) / Buddha Seeds (Original Originator of "Magnum")

  • Lineage: Unknown Sativa Hybrid x High-Vigor Ruderalis (Rumored to contain Jack Herer or Haze genetics)

  • Market Status: The "Size Booster"; Super Magnum Auto is rarely sold as a standalone packet in the modern market; it is the "Secret Weapon" hidden inside the DNA of Barney’s Farm's best sellers. It is the genetic engine responsible for making strains like LSD Auto and Skywalker OG Auto grow so large. Before Magnum arrived on the scene, autoflowers were tiny "Lowryders." Super Magnum changed the game by proving autos could grow 1.5 meters tall and yield like photoperiods.

  • THC Content: 17% – 21% (Moderate & Clear)

  • Dominant Terpenes: Limonene, Pinene, Caryophyllene, Terpinolene

  • Key Effects: Energetic Buzz, Social Giggliness, Mental Clarity, "Daytime" Motivation


If you wonder why modern Barney’s Farm autoflowers yield 500g/m² instead of the 20g per plant of the early 2000s, Super Magnum Auto is the answer.

This strain was bred to solve one problem: Size. Early autoflowers were bonsais. Super Magnum is a giant. It passes on a "Sativa-like" stretch and an explosive root system to its offspring. It is the reason you can now grow an auto that looks and yields like a full-season plant.


History and Lineage: The Birth of the "Super Auto"

This strain represents a pivotal moment in autoflower history.

  • The Origin: The original "Magnum" was developed in Spain (likely by Buddha Seeds) to maximize the yield of autoflowers. They crossed powerful Sativas (theories range from Jack Herer to Super Lemon Haze) with a very large Ruderalis.

  • The Upgrade: Barney’s Farm developed their own line, dubbed Super Magnum Auto. They selected phenotypes that were even faster and more resistant to mold, creating a "male" donor that could be crossed with legendary cuts like LSD or Blue Cheese.

  • The Role: It acts as a "canvas." It provides the size and the automatic flowering trait, but it is "recessive" enough in flavor that the mother plant (e.g., LSD or Skywalker) can still dominate the taste profile.


Terpene Profile: Fresh Spices and Citrus

Because it is a breeding tool, the flavor of pure Super Magnum is clean, spicy, and functional—it doesn't overpower the cross.

Dominant Terpenes

  • Limonene (The Freshness): The dominant note. It provides a sharp, clean citrus aroma, similar to fresh lemons or lime zest.

  • Pinene (The Forest): Adds a distinct pine and metallic scent. This "fresh" smell is a marker of high-vigor Sativa genetics.

  • Caryophyllene (The Spice): Gives the strain a spicy, peppery kick that lingers on the tongue.

Flavor Notes:

  • The Aroma: It is fresh and pungent. It smells of spicy herbs, pine needles, and lemon cleaner.

  • The Smoke: Light and airy. It tastes of incense, metal, and citrus peel. It is a very "Old School Sativa" flavor profile.


Strain Effects: The Social Butterfly

When smoked on its own (as Magnum), the effects are distinctly different from the heavy Indicas it is often crossed with.

The Experience

  1. The Head Rush: The high is almost entirely cerebral. It triggers a laughing, happy buzz immediately.

  2. The Energy: It is a stimulant. You feel an urge to move, clean, or socialize. There is zero couch-lock.

  3. The Clarity: It does not cloud the mind. You remain functional and sharp, making it a favorite for daytime smokers.

  4. The Paranoia: Because it is a racy Sativa auto, it can cause mild anxiety in low-tolerance users if smoked too heavily.

Best For: Social gatherings, outdoor activities, cleaning the house, and breeding projects.


Growing Super Magnum Auto: The Root Monster

This is the trait that Barney’s Farm wants. This plant grows aggressively.

Growth Structure

  • The Roots: Super Magnum is famous for its explosive root growth. If you plant it in the ground, the taproot dives deep, allowing the plant to support a massive frame.

  • The Size: It is a Giant. Pure phenotypes can easily reach 120cm – 150cm (4 to 5 feet) outdoors.

  • The Branching: It branches laterally like a photoperiod plant. It does not grow as a single stick; it grows as a bush.

  • The Appetite: It is a heavy feeder. To fuel its rapid growth, it consumes high levels of Nitrogen in veg.

  • The Time: It has a slightly longer cycle than small autos, often taking 10 to 11 weeks to reach full maturity.

Grower’s Tip: If you ever grow a cross involving Super Magnum (like LSD Auto), do not use small pots. The genetics are programmed to search for space. If the roots hit the bottom of a small pot early, the plant will "sense" the restriction and flower early, staying small. Give it at least 15-20 Liters (4-5 Gallons) to unlock the "Super" size.


Final Verdict: The Unsung Hero

Super Magnum Auto is the offensive lineman of the cannabis world: it does the heavy lifting so the star players (LSD, Skywalker, Blue Cheese) can score the touchdowns. It is the genetic engine that allows Barney’s Farm to sell autoflowers that yield 500g/m². While you might not smoke it for its flavor alone, you have to respect it for changing the perception of what an autoflower can be.

You should choose strains with Super Magnum lineage if:

  • You want Massive Yields from an auto.

  • You grow Outdoors (It loves open soil).

  • You want Mold Resistance (Open Sativa structure).

  • You want a "Photoperiod-sized" plant in 70 days.

Score: 9.0/10 (The Genetic Engine)
