White Widow is the most repeated name in any seed catalogue and, in ours, the largest family: the same selection comes in three versions, feminized, autoflowering and fast version. They share lineage and much of their character, but they do not behave the same way. In this guide we compare the three using the data on their product pages, so you can see what changes from one to another and which one fits your collection best.<\/p>\n

One family, three behaviours<\/h2>\n

All three versions come from our own mother plants, selected and kept at our seed bank in Barcelona. The base is the feminized White Widow<\/a>, whose documented cross is Widow Bilbo \u00d7 Widow BCN: two Widow lines selected separately and brought together to fix the strain’s aroma and structure.<\/p>\n

From there, what changes is what triggers flowering. The feminized version is photoperiod-dependent: it flowers when the light cycle changes. White Widow Auto<\/a> carries ruderalis in its cross and flowers with age, regardless of the photoperiod. White Widow Fast<\/a> sits in between: it is still photoperiod-dependent, but a ruderalis contribution in its ancestry shortens flowering without making it automatic.<\/p>\n

These are catalogue figures declared for the parent lines, useful for comparing strains with each other; they are not a measurement of each seed nor a guarantee of results.<\/p>\n

Feminized White Widow: the reference<\/h2>\n

This is the version that defines the family. Its genotype, 60% indica and 40% sativa, places it halfway between compact indicas and long-cycle sativas, and its declared THC range (18\u201323%) is the highest of the three. The trait that made it famous is still its visual signature: a dense, pale layer of resin over the bud and nearby leaves, the detail that gives the whole “white” family its name. It is the natural choice for anyone who wants the classic White Widow with the most complete aromatic profile.<\/p>\n

White Widow Auto: independent of the photoperiod<\/h2>\n

The ruderalis contribution changes the plant’s logic: the switch to flowering depends on its age, not on hours of light. The product page describes a small to medium plant, 70 to 110 cm tall, with a well-defined main cola. Its aroma is the furthest from the rest of the family, an intense floral note that is unusual in the catalogue, and in late flowering it can show pink and purple hues depending on the phenotype and environment. This is the version for anyone looking for the White Widow lineage in a compact autoflowering format.<\/p>\n

White Widow Fast: the shortest cycle<\/h2>\n

The fast version keeps the photoperiod behaviour of the feminized one but shortens flowering: 40\u201349 declared days versus 47\u201356, the shortest cycle in our whole fast collection. In exchange, its declared THC range (15\u201320%) is somewhat lower than the feminized version’s. In aroma, it concentrates the backbone of the line into three notes: earth in the background, pine lifting it and a spicy touch behind. It suits anyone who wants the classic feminized character on a faster cycle.<\/p>\n
