The collection / 03
Autoflower describes a flowering trait associated with plant age rather than a change in day length. Discover how that label relates to photoperiod and feminized descriptions.

Autoflower and photoperiod describe flowering traits. They do not, by themselves, tell you whether a variety is feminized or regular.

Understanding the collection
Start with the flowering trait, then look at the other information in a description. Four short chapters separate the terminology from assumptions about a particular variety.
Autoflowering describes flowering associated with plant age rather than a change in day length. It is a description of a plant trait, not the name of a single strain.
The useful first question is what a label describes. Here, that is flowering behaviour. Other fields in a description need to explain sex characteristics, the named variety and any documented specifications.
Photoperiod refers to flowering responsive to day length. Autoflower describes a different flowering trait. This is the comparison to make when you are trying to understand what the word autoflower means.
Neither heading provides a complete profile of every variety within the group. Keep a broad category description separate from any specific claim about an individual entry.
Feminized describes seeds bred to favour female plants. Autoflower describes a flowering trait. Those terms can appear together because they answer different questions.
Do not read autoflower as a replacement for feminized or regular. Look for each characteristic separately when interpreting the full description of a named variety.
The word autoflower is not a documented duration for a particular variety. This page does not attach generic time estimates to all of the names in the index.
Specific details need their own source. We have left out unverified durations, percentages, prices and availability claims until the individual product information is available.
Autoflower is a useful category label when its meaning is kept clear. It should not stand in for a complete variety description or a set of verified measurements.
The strain cards are general name references. Their botanical illustrations are not evidence that an autoflower variant is available. Verified variants will need their own descriptions.
The autoflower FAQ
Autoflower refers to a flowering trait associated with plant age rather than a change in day length. It is one characteristic of a variety, not a complete specification.
The word autoflower alone does not establish that. Autoflower and feminized describe separate characteristics, so check whether both labels are stated for the individual variety.
They describe different flowering traits: autoflower is associated with age, while photoperiod flowering responds to day length. Neither term is a strain name.
No. The category label alone is not a verified timetable for an individual variety. We do not assign a universal duration to entries in this index.
The cards lead to general strain histories. A familiar name does not establish that every example has the same flowering behaviour.
