A high-caliber autoflower for monster yields
Magnum, a high-quality autoflowering strain developed by Spain-based Buddha Seeds, is one of the most prolific autoflower varieties on the market. Born of a clandestine three-way genetic concoction, it’s a blend of different strains with unique traits and one key commonality—their remarkable bud production.
The auto has been fine-tuned to give the large, dense blooms of Indicas, the ease of growth and robustness of Ruderalis plants, as well as the invigorating and stimulating highs of Sativas.
Magnum has decent THC content that ranges from 12 and 15%. While that may appear too small, it is plenty for introverts who require a gentle prod to come out of their shell. As soon as the euphoric high sets in, users feel elevated and more social. It may also turn anyone into a chatty Charlie and cause endless chuckling, making this cannabis bud great for a light, welcoming environment. Furthermore, the strain increases energy and has a near-unrivaled capacity to reduce exhaustion, tension, and worry.
Magnum is perfect for growers who desire a straightforward yet high-yielding grow operation. It requires little effort to produce loads of flowers bursting in powerful spicy fragrance. Despite being an autoflower, the plant can grow quite tall and wide if left to its own devices. If this isn’t a deal-breaker, it’s an excellent practice strain for those with black thumb and cannabis enthusiasts who want a quick turnout.

Magnum is a simple strain to cultivate. It starts fruiting soon after germination and does not require much work. Its sturdy structure can withstand a variety of difficulties, including weather changes, powerful gusts of wind, and common pests and diseases that attack cannabis plants. Even so, growers must pay attention to numerous environmental elements because they might affect the quantity and quality of buds produced by this strain.
Indoors is the best place to cultivate Magnum. Growers can regulate temperature, humidity, and lighting in a controllable environment. Air circulation can also be managed by installing ventilation systems and fans. With proper airflow, the accumulation of excess moisture, which invites mold, mildew, and other pathogens into the grow area, can be prevented.
Indoor cultivators who want cannabis plants that are manageable in size or have limited room should avoid growing Magnum in huge pots. To keep its above-average height under control, grow it in tiny places, small pots, or opt for late transplants. On the other hand, outdoor growers may plant Magnum straight into the soil or in large pots, allowing it plenty of room to flourish to its full potential.
Magnum reaches 100 to 150cm high. It is bigger than most autoflower varieties, but it’s still short compared to photo periods. Its indoor yield is also above your average auto, producing up to 550 to 600 grams per square meter. Outdoors, the strain can generate between 100 and 250grams per plant, with the months from July to October the most productive. Magnum only takes 11 weeks to go from seed to harvest.
Some cultivators are not fans of autoflowering varieties, claiming that the autos produce buds that lack fragrance and potency. While this may have been true in the past, it is less of a concern nowadays, thanks to the productive and high-caliber auto cultivars like Magnum.
Furthermore, growing this strain is relatively simple because it is inherently resistant to pests and fungi. Its autoflowering seeds are also feminized with minimal hermaphroditic tendencies, so there is hardly any chance of producing male plants even when the ladies are subjected to minor stress levels.
Still, providing ideal environmental conditions is crucial in helping Magnum and other autoflowers achieve their highest production potential.
When cultivating autoflowering cultivars outdoors, the climate significantly impacts the yield. Outdoor cannabis gardeners rely on the seasons to produce decent yields from autoflowers. This is because autoflowering marijuana plants require the correct temperature, humidity, and sunshine to thrive, and the quality and number of buds you harvest will reflect this.
Growers in hot, sunny places can grow Magnum all year round with excellent results. However, those who have shorter summers and cold winters may not harvest as much as those who live in a tropical climate, where they can expect to grow multiple times per year with great results.
Now, when growing indoors, you don’t have to worry about the climate or the weather because you can control every aspect of the growing conditions. This can be a good thing for more experienced growers. Sadly, if you’re new to growing indoors, it can be quite tricky if you don’t have access to or can’t afford the right equipment.
For the most part, growing Magnum indoors only requires an 18/6 or 20/4 light cycle and the use of 600W lamps.
Magnum and most other autoflowers are not picky and are naturally sturdy. Still, they require specific conditions at different stages of development to mature to their full potential. The general rule is to keep the temperature between 18 to 24°C and the humidity around 70% in the vegetative stage, gradually decreasing to 60% near the pre-flowering stage. When your Magnum begins fruiting, adjust the humidity to approximately 50%, decreasing to 40 to 45% as harvest draws near.
Feeding your Magnum with a high-quality supply of nitrogen, phosphorus, and potassium, also known as NPK or the Big 3 macronutrients, and essential micronutrients is one way to boost its productivity. Growers may also use organic fertilizers or living soil, but a proper watering ratio must always be followed.
If you’re planning to use synthetic nutrients, you no longer have to maintain a healthy soil as synthetic nutes can kill the microorganisms in the medium. This makes feeding more straightforward, but at the same time, the plants also become prone to overfeeding and nutrient burn.
