Sativa seeds come with more vocabulary attached than any other category of cannabis seed, and a good deal of it means one thing to a botanist, something else to a seed company and something different again to the person trying to make a decision in front of the pack. A disappointing sativa grow usually goes back to a word that was understood in the wrong sense: a flowering time read as a promise, a “sativa-dominant” tag read as a statement of effect, a landrace chosen like it were a modern hybrid. The entries below are put together with the range at https://hazesativaseeds.com to hand for the concrete examples, because it leans heavily towards the long-flowering end of the spectrum and that is where the vocabulary carry the most weight most; the definitions themselves hold to any sativa seed from any seller. They are given in no special order, because none of them makes usable without the others.

Intersex tendency

The production of pollen-bearing flowers on a female plant, usually towards the end in flower and frequently under stress. Almost every cannabis line carries some capacity to do; long-flowering lines express it more often, for a simple one: sixteen weeks of flower is sixteen weeks of exposure for a timer leak, a temperature spike or a late watering that can trigger it off, and an plant that has waited beyond its intended finish often throws a few desperate pollen flowers on its own as a last attempt to set seed.

Not one of this means a sativa line unstable by course; it means the grower’s consistency count over longer. Light-tight tents, steady temperatures and cutting the moment the plant is ready and not two week after remove the greater part of the problem. A listing that mentions a breeder screens parents for hermaphrodite traits is worth more on a long-flowering line than on anything other category.

Haze

Originally a specific family of plants put together in 1970s California from Mexican, Colombian and South Indian landraces, and then preserved and worked in the Netherlands. The Haze grows tall, fills out openly, flowers for twelve to sixteen weeks and smells of spice, citrus and something sharp that no other line quite has.

In its looser sense “Haze” is any cross that carries a share of that family, and by now is most of the sativa-leaning market. A listing that says “Haze” without lineage may be eighty percent original classic family or one sixteenth of it, and the grow time follows the share, not the name. The useful question is never “is it a Haze” but “how much, and via which parent”.

Stretch (the doubling)

The surge of upward growth which comes after the switch to flowering. Indica-leaning plants add around half again; sativas commonly double, and a few landrace lines go further. The stretch lasts two to five weeks and cannot be halted once it has started, only bent sideways by training.

In practical terms, a stretch figure is the fact to reading ahead of deciding when to flip. A sativa switched at sixty centimetres inside a standard tent is at the lamp by week four of flower; one switched at thirty centimetres centimetres has room. People moving from indica strains nearly always switch too late the first time, and the lesson is written on the ceiling of the tent.

Sativa-dominant

A marketing category and not a botanical one. It usually indicates that the larger share of a hybrid’s parents are described as sativa according to the breeder who wrote the description, and occasionally means no more than a certain the flowers are airier or the aroma brighter than the that breeder’s other releases.

The experience people associate with the word, lively rather than sedating, is governed more by terpene profile and the cannabinoid content than by the sativa fraction, and a good number of “sativa-dominant” releases deliver a heavy couch result while plenty of the opposite lines do the reverse. For a buyer the percentage is worth something as a rough hint to growth habit, flowering time and stretch; as a guide to how it feels it is next to useless without the terpene notes.

Latitude (outdoor sativas)

The single figure that determines whether a sativa will finish outdoors, and a number no pack prints. Equatorial lines require the run of shortening days to go on long enough to let the plant to finish; at high latitudes the frost comes before that, and the grower cuts a unripe plant in late October or loses it to mould in November. The closer to the equator, within the northern hemisphere, the later the season stretches, and coastal or subtropical gardens are able to ripen plants that northern growers cannot.

The practical rule of a seed pack: an “outdoor” sativa harvest month is given for the breeder’s home latitude, usually somewhere within temperate Europe or the west coast of the United States, and every step north of that pushes the finish back towards the frost. A grower north of roughly the fiftieth parallel that wants a true sativa outdoors is shopping for an autoflower or a greenhouse, and not a longer season.

Equatorial

Refers to lines from latitudes where daylength barely changes across the year, which means where the plant does not develop a strong response to shortening days. Such lines often start flowering slowly under a standard twelve-hour schedule, since twelve hours is, to them, a mild ordinary day and not a signal.

The practical fix, handed around between sativa growers for decades, is to cut the light more: eleven hours, sometimes ten, particularly in the final weeks. It costs a yield yield and gains a earlier decisive end. A listing which uses “equatorial” is telling you this in one word, and a grower that takes it as a note on geography misses the instruction inside it.

Terpinolene

A terpene found in high amounts in a lot of old sativa strains and responsible for much of the thing growers describe as the “sativa” aroma: green, woody, lemon and slightly floral all at once. It is volatile, lost easily by fast drying, and it fades more quickly during storage than the heavier terpenes which lead indica-leaning lines.

To a seed buyer the word does two things. When a listing names terpinolene among the lead aromas, the line most likely carries real old-sativa genetics regardless of what the label claims. And where the grower wants that smell to survive by the jar, the cure has to be cool and cool; a fast dry flattens a terpinolene line to something that smells of very little and nothing of what the pack promised.

Flowering time (and what it is counted from)

The number of weeks between the onset of flowering and maturity, and the single most frequently misunderstood number on a sativa pack. For photoperiod seed it is measured from the day the light drops to twelve hours, not from sowing, so a “fourteen-week” sativa grown with a ordinary vegetative period is a twenty-two-week plant. Seed companies also give the shorter end of a spread, since the longer end sells fewer seed.

Sativa lines run anywhere from ten weeks to well over twenty, and the longest strain in the Haze Sativa Seeds range comes in at about 16 weeks after the switch. The catalogue can be filtered by this number, which is a sensible first step for a room with a fixed timetable. A grower who adds four weeks to whatever the pack says is rarely caught out.

Foxtailing

The habit of some flowers to grow new calyx clusters on top of existing ones, giving towered, irregular buds instead of round ones. In the majority of tent-bred lines it is a heat response, typically from light that is too close or a room that is too high, and the standard response is to correct the cause.

In many sativas, above all Southeast Asian and some Haze lines, it is genetic and will happen in a flawless room. A first-time sativa grower frequently wastes weeks hunting a problem that was never there, lowering lights and temperatures and slowing an already long flower further. The breeder rarely warns which kind you should expect; the lineage generally tells you.
