Amsterdam Finest!

White Widow XTRM. This autoflower is among the strongest weed in the world. Born and bred right here in our beloved Amsterdam. Although many countries claim to have created White Widow, we can state that here in Amsterdam; White Widow first saw the light of a lamp. This weed has won more Cannabis Cups than any other strain before.

There is a reason behind the higher prices of the White Widow XTRM autoflower in most Dutch cannabis dispensaries. In addition to her excellent characteristics, she is the epitome of recreational and medicinal effects.

Here at AMS, it is somewhat daunting to distinguish our White Widow extreme seeds from the original White Widow as the strain seedlings begin to grow. That is what we mean when we say that we like tailoring each of our strains to be a replica of the original while maintaining the desired characteristics.

Strain Characteristics

White Widow XTRM autoflower is a powerful plant that can be grown anywhere. Perfect for novice growers. It is among the strongest strains in the world. Mold and caterpillars tend to avoid attacking this variety due to their robust nature. It is fibrous enough to repel most cannabis predators, and its strength extends to the fact that strong winds rarely adversely affect the plant. As is the case with her mother, the classic but highly regarded White Widow, she maintains her physical attributes, including her prominent white Trichomes.


The buds are huge, so be prepared to harvest up to 400 Grams (14 Ounces) per 1 m2 (11 ft2) when grown indoors and up to 600 Grams (21 Ounces) per 1 m2 (11 ft2) outdoors. As you probably already know, autoflower plants will enter the flower phase at a defined point in their growth instead of being influenced by daylight hours. This undoubtedly makes them much more predictable when it comes to harvesting.


White Widow XTRM autoflower grows compact; like all autoflowers, the mix with ruderalis affects the height. But not to worry, she does get you plenty high!
