How to Grow Magnum Autoflower Seeds

Autoflower strains are unique because they allow growers to cultivate weed on cruise control.

However, there are aspects that need attention when growing autos, such as Magnum. Below, we’ll discuss important details, such as grow difficulty and flowering time.

Once you complete this section, you’ll have a clear idea of how to grow Magnum Auto seeds from start to finish.

Grow Difficulty

The Magnum Auto strain is relatively easy to grow indoors or outdoors.

We say relatively because Magnum Auto may catch you off guard if you’ve never grown autoflowering strains before. For instance, Magnum Auto is an extremely vigorous plant that grows similar to regular and feminized strains.

As such, here are a few tips to ensure your Magnum Auto crop goes off without a hitch:

  • Consumes a moderate to high amount of nutrient
  • Can become large without training techniques
  • Requires support poles to prevent broken branches
  • Ideal for small containers and small spaces

Overall, the Magnum Auto strain is a true K.I.S.S. type of cultivar — don’t overthink it!

Optimal Growing Conditions and Climate

The Magnum Auto strain prefers a Mediterranean climate.

However, this isn’t to say that Magnum Auto can only be grown in ideal locations. Instead, climates that do not experience frost from late September to early October are suitable for Magnum Auto plants.

If you grow Magnum Auto seeds indoors, you must:

  • Provide bright light (LED or HID)
  • Medium to large quantities of plant nutrient
  • Consistent irrigation
  • Adequate plant spacing

If you grow Magnum Auto seeds outdoors, you must:

  • Plant in a sunny location
  • Protect from the elements
  • Adequate plant spacing

Most importantly, Magnum Auto does not require a photoperiod to flower. Autoflowers are unique because they flower according to their internal clock.

Therefore, you can grow Magnum Auto seeds year-round as long as the plants don’t undergo frost.

Flowering time

The Magnum Auto strain flowers in roughly 8-weeks.

However, many phenotypes of the Magnum Auto strain lean towards its sativa lineage, thus pushing the flowering time to 9-weeks. Therefore, you must be prepared to flower Magnum Auto well into October if you’re cultivating it outdoors.

You’ll likely land on the 8-week mark if you cultivate Magnum Auto seeds indoors. In any case, always use a magnifying glass to confirm trichome ripeness.


It isn’t called Magnum Auto for nothing — especially since it produces upwards of 500-grams per meter squared indoors.

In general, autoflowering strains produce a mediocre harvest compared to regular and feminized seeds. However, Magnum pushes the envelope and generates a hefty harvest of resin-covered buds for anyone to enjoy.

Outdoors, Magnum Auto is known to produce nearly 200-grams per plant.


The Magnum Auto strain is a relatively short plant, making it ideal for small spaces and reduced plant containers.

However, Magnum Auto grows extremely fast. Remember, Magnum is an autoflowering strain, meaning it does not require a vegetative time.

Instead, Magnum Auto relies on an internal clock that tells it when to flower. Overall, here are a few tips to keep the height in check in the event that your plants are too big for your space:

  • Use the topping method to create bushier (as opposed to lateral) growth
  • Harness the LST method to pull side branches down to create an open canopy

Resistance to Pests and Diseases

Magnum Auto is moderately resistant to pests and diseases.

Although Magnum is naturally equipped to handle common problems — it’s in your best interest to have your IPM program ready. Below, we’ve outlined the most important tips on maintaining a pest and diseases-free cannabis garden.

  • Apply organic pesticides 1-3 times prior to flowering
  • Trim undergrowth to improve air circulation
  • Space plants accordingly
  • Ensure climate (temperature and humidity) are at ideal levels
  • Provide adequate nutrition and water applications
