The Sativa Dictionary: Ten Words to Learn Before You Buy
Sativa seeds come with more vocabulary attached than any other category of cannabis seed, and most of it says one thing to a botanist, something else to a seed company and something different again to the grower trying to make a decision in front of the listing. The failed sativa grow nearly always goes back to a word that was understood in the wrong one of those senses: a flowering time read as a fixed number, a “sativa-dominant” tag read as a statement of character, a landrace bought as if it were a tent-bred hybrid. The entries below are written with the range at https://hazesativaseeds.com open for the concrete examples, because it runs 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 not one of them makes usable without the rest.
Equatorial (the twelve-hour problem)
Refers to plants out of latitudes in which daylength barely changes across the year, and that the plant does not evolved a sharp reaction to shortening days. These plants often flower reluctantly at a conventional twelve-hour light cycle, because twelve hours is, for them, an unremarkable day rather than a signal.
The working fix, handed down between sativa growers over decades, is to cut the light further: eleven hours, sometimes ten, especially in the final weeks. It costs some yield yield and buys an earlier decisive end. A listing that uses “equatorial” is telling you this in one word, and a grower that takes it as mere origin has missed the point hidden in it.
Stretch (the doubling)
The burst of vertical growth that follows the switch to flowering. Indica-leaning plants gain half again; sativas commonly double, and a few landrace types go further. The stretch continues two to five weeks and cannot be halted after it has started, only redirected by training.
In practical terms, the stretch figure is a fact worth reading before deciding when to flip. A sativa switched at sixty centimetres inside a two-metre tent is at the lamp before week four of flower; one switched at thirty centimetres has room. People coming over from indica strains almost always flip far too late the first time, and the lesson is written on the ceiling of the tent.
Terpinolene (the “sativa smell”)
A aromatic compound present in high amounts in many classic sativa strains and accounting for much of what growers mean as the “sativa” smell: fresh, woody, citrus and faintly sweet at once. It is fragile, driven off easily by hot drying, and terpinolene fades faster during storage than the earthier terpenes which dominate most tent stock.
For a seed buyer the name earns two jobs. When a listing names terpinolene among the lead aromas, the line probably has real Haze-era genetics regardless of what the percentage says. And when the you are after that profile to still be there by the jar, the cure is going to be cool and cool; a warm drying room flattens a terpinolene sativa to a flower that smells of hay and no trace of what the pack described.
Foxtailing
The habit of certain flowers to push out fresh bud growth on top of existing ones, producing spired, irregular buds instead of round ones. In the majority of indica-leaning strains it is a heat response, usually from light that is too close or temperatures too high, and the advice is to correct the cause.
In a good number of sativas, especially Southeast Asian and certain Haze lines, it is genetic and is going to occur under a perfect room. A first-time sativa grower frequently spends a month hunting a fault that is not there, lowering lights and heat and delaying an already slow flower further. The breeder seldom says which kind to expect; the lineage generally tells you.
Hermaphroditism in long-flowering lines
The appearance of male flowers on a female plant, typically towards the end in flower and frequently in response to stress. Almost every cannabis line has some tendency for it; sativa lines show it more often, and the reason is a plain one: sixteen weeks of flower is sixteen weeks of opportunity for a timer leak, a heat spike or a late watering that can trigger it off, and an old that has gone past its natural finish often produces a few desperate male flowers on its own in a final effort to make seed.
Not one of this means a sativa line unstable by nature; it makes the grower’s consistency count over a longer stretch. A sealed tents, steady conditions and harvesting the moment the plant is ready and not a weeks after remove the greater part of the risk. A listing that mentions the breeder tests parents for hermaphrodite tendency is saying something worth hearing for a long-flowering line than on anything other category.
Landrace versus heirloom
A population of plants shaped through generations to a particular place by the local climate and climate alike, and not by deliberate selection. Thai, Colombian, Malawian and Mexican lines are the classic sativa cases. A landrace is variable, not a one plant: within a pack the heights, finishing times and aromas range widely than in any tent-bred line, and that variation is the point of keeping one.
The mistake is treating a landrace as a modern product. It brings traits that make sense in an equatorial field, such as a frame no tent can hold and a flowering rhythm tuned to a daylength the majority of growers cannot offer. “Heirloom” on a listing usually refers to a landrace that has been grown out away from its origin over some generations, often with light selection towards indoor life; it is closer to manageable but still not uniform. A seller listing “landrace” without a collection region and a reproduction history is using the word loosely, and the seeds should be judged accordingly.
Sativa-dominant (the label)
The catalogue term rather than a measurable one. The phrase usually means that more of a hybrid’s lineage are described as sativa according to the breeder who drafted the listing, and sometimes signals no more than a certain the buds are longer or the aroma brighter than the that breeder’s other lines.
The effect people connect with the word, clear-headed rather than heavy, is driven more by terpene chemistry and the cannabinoid content than by ancestry, and a good number of “sativa-dominant” releases produce a heavy sleepy result while plenty of indica-labelled stock deliver the reverse. To a buyer the label is useful as a loose guide to growth habit, flowering time and stretch; as a predictor to how it feels it is close to worthless without the terpene description.
Flowering time (and what it is counted from)
The number of weeks from the onset of flowering and maturity, and the single most misread number on a sativa pack. With photoperiod seed it is measured from the day the light is cut to twelve hours, rather than from sowing, so a “fourteen-week” sativa started after an ordinary vegetative stage is a twenty-two-week plant. Seed companies also quote the shorter end of a spread, because the longer end moves less seed.
Long-flowering lines take everywhere from ten weeks to more than twenty, and the slowest line in the Haze Sativa Seeds range is at around 16 weeks from the flip. The catalogue can be sorted by this number, which is the reasonable first pass if you have a room with a tight timetable. A grower who allows four weeks to whatever the pack says is seldom disappointed.
Latitude (outdoor sativas)
The single figure that decides if a sativa will ripen outdoors, and a number that no pack prints. Long-flowering lines require a autumn days to go on long enough to let the plant to ripen; at high latitudes the frost arrives first, and the grower harvests an half-finished plant in late October or else watches it rot in November. The closer south, within a northern hemisphere, the later the season stretches, and Mediterranean or subtropical growers can finish lines that northern growers never will.
The usable reading of a seed listing: an “outdoor” line finishing month is given for the breeder’s own latitude, usually a point in temperate Europe or the west coast of the United States, and every step north of it pushes the finish back towards the weather. A grower above about the fiftieth parallel who is after a true sativa outdoors is shopping for a sativa autoflower or a covered space, not a better season.
Haze (the family, not the smell)
In its first sense a specific family of plants put together in 1970s California from Colombian, Colombian and Thai landraces, and later preserved and refined in the Netherlands. A true Haze runs tall, branches sparsely, flowers for twelve to sixteen weeks and carries a scent of spice, pine and something sharp that no other line quite has.
In its second sense “Haze” is whatever cross that carries some of that family, and today is a great many of the sativa-leaning market. A listing which reads “Haze” without parents may be eighty percent the classic family or one small fraction of it, and the flowering time follows the share, not the name. The useful question is never “is it a Haze” but “how much, and through which parent”.
