How to grow Magnum Auto

The Magnum Auto cannabis plant is one of the easiest auto-flowering varieties to grow. It adapts to indoor and outdoor conditions, warm and temperate climates, beginner and veteran growers… You can always expect an excellent result.

We recommend using a large pot with good substrate from the first day. This way, the plants will grow without the typical halt that sometimes occurs after a transplant and will reach a height of up to 130 cm. It is not the most discreet auto-flowering due to its large size, but it is undoubtedly one of the most productive.

From germination, it is harvested in about 80-85 days, allowing for up to 2 consecutive outdoor crops during the spring and summer months.

Characteristics of Magnum Auto

The buds are of a brutal size, very compact and resinous. The flowers from the nodes join together to form long tails the size of baseball bats, very easy to manicure.

It dominates a very fresh and appetizing menthol aroma and flavor, with woody, spicy, and slightly herbal touches that will make your taste buds vibrate.

The effects are potent and well balanced but with a dominance of its Sativa genes. The body is filled with energy and creative ideas flow from the mind that you will want to share with others.

Yields are very high. Outdoors, larger plants will easily reach 250 grams of dry buds. Indoors, anyone can get up to 600 grams per m² with 300-350 W LED.
