Sativa Seeds, Term by Term

Sativa seeds come with more vocabulary attached than any other kind of cannabis seed, and a good deal of it means a certain thing to a botanist, another to a seed company and something different again to the grower trying to make a decision in front of the pack. The disappointing sativa grow usually traces back to a word that was read in the wrong one of those senses: a flowering time read as a promise, a “sativa-dominant” tag read as a statement of effect, a landrace bought as if it were a modern hybrid. The entries below are put together with the range at https://hazesativaseeds.com to hand as reference, since it runs strongly to the classic end of the category and that is where the words carry the most weight most; the definitions themselves hold to any sativa seed from any seller. They are given in no particular order, since none of them makes usable on its own without the others.

Terpinolene

A aromatic compound found in large amounts in many classic sativa lines and responsible for most of the thing growers mean as a “sativa” smell: green, woody, citrus and faintly floral all at once. It is fragile, driven off easily through hot drying, and it fades faster in storage than the heavier terpenes that lead most tent stock.

For a seed buyer the word earns two things. Where a listing lists terpinolene among the lead aromas, the strain most likely has substantial old-sativa ancestry whatever the percentage says. And when the grower are after that smell to still be there by the jar, the drying is going to be cool and slow; a warm dry turns a terpinolene line to something that tastes of hay and no trace of what the pack promised.

Intersex tendency

The appearance of male flowers on a female plant, typically late in flower and often under stress. Every cannabis line carries some tendency to it; sativa lines express it more often, for a simple one: fourteen weeks of flower is sixteen weeks of opportunity for a timer leak, a temperature spike or a missed watering to trigger it off, and a plant that has waited beyond its intended finish frequently produces a few late pollen flowers on its own in a last attempt to make seed.

None of this makes a sativa line weak as a matter of course; it makes the grower’s consistency count for a longer stretch. A sealed tents, steady conditions and cutting the moment the plant is ready rather than a weeks later remove the greater part of the risk. A listing which states a breeder screens parents for hermaphrodite tendency is saying something more for a sativa than on any else.

Stretch

The surge of upward growth that follows the change to flowering. Indica-leaning plants gain half again; sativas routinely double, and some equatorial lines triple. The stretch continues three to five weeks and cannot be stopped after it has started, merely redirected by training.

In tent terms, a stretch figure is a number to read ahead of deciding when to flip. A sativa flipped at sixty centimetres centimetres in a two-metre tent is at the lamp before week four of flower; one flipped at thirty centimetres centimetres has room. People moving over from indica strains nearly always flip far too late the first time, and the consequence is visible on the ceiling of the tent.

Landrace

A population of plants shaped over centuries to a particular region by the local growers and growers together, rather than by modern selection. Colombian, Thai, Malawian and Oaxacan stock are the classic sativa examples. A landrace is variable, rather than a single plant: inside a pack the flowering times, flowering times and aromas spread widely than in any tent-bred line, and that variation is the point of keeping one.

The mistake is treating a landrace as a finished hybrid. It carries traits that made sense in an open field, including a frame that no tent can hold and a flowering rhythm set to an daylength the majority of growers cannot offer. “Heirloom” in a listing usually means a landrace that has been reproduced away from its origin for some generations, often with a degree of selection towards indoor life; it is nearer to manageable but nonetheless not a hybrid. A shop offering “landrace” without a collection point and a reproduction count is using the word loosely, and the seeds should be priced with that in mind.

Sativa-dominant (the label)

A catalogue category rather than a measurable one. The phrase usually indicates that more of a hybrid’s parents were classed as sativa according to the breeder who drafted the listing, and occasionally means nothing more than a certain the flowers are airier or the aroma brighter than the that breeder’s indica-labelled releases.

The experience people associate with a word, clear-headed rather than heavy, is governed far more by terpene chemistry and the THC content than it is by the sativa fraction, and a good number of “sativa-dominant” hybrids deliver a flat couch effect while a good number of the opposite lines do the reverse. For a grower the percentage is worth something for a loose guide to growth habit, flowering time and stretch; for a predictor to how it feels it is next to useless unless accompanied by the aroma notes.

Latitude (outdoor sativas)

The one number that determines if a sativa will finish outdoors, and one no pack states. Long-flowering plants need a autumn days to continue long enough to let the plant finish; at northern latitudes the frost arrives first, and the grower harvests an unripe plant in late October or else watches it to mould in November. The further south, within the northern hemisphere, the later the season stretches, and Mediterranean and low-latitude growers are able to finish lines that temperate growers never will.

The practical rule of a seed listing: an “outdoor” line finishing month is given for the breeder’s own latitude, usually somewhere in temperate Europe or the western United States, and every step further north of it moves the finish back towards the frost. A grower above roughly the fiftieth parallel that is after a true sativa in the garden is looking for a sativa autoflower or else a greenhouse, and not a longer season.

Haze (the family, not the smell)

Originally a specific line of plants put together in 1970s California from Colombian, Colombian and South Indian parents, and later kept and worked in the Netherlands. The Haze runs tall, branches sparsely, takes for twelve sixteen weeks and carries a scent of spice, citrus and something metallic that no other other line quite has.

In its looser sense “Haze” is any hybrid that carries a share of that family, which by now is most of the sativa-leaning market. A listing that reads “Haze” and gives no lineage may be eighty percent original old family or a small fraction of it, and the flowering character follows the share, not the name. The working question is not “is it a Haze” but “how much, and through which parent”.

Equatorial (the twelve-hour problem)

Refers to lines from regions in which daylength barely varies across the year, and that the plant does not develop a strong reaction to changing days. Such plants frequently flower reluctantly at a conventional twelve-hour light cycle, because twelve hours is, to them, a mild unremarkable day rather than a signal.

The working response, handed down among sativa growers for decades, is to cut the light more: eleven hours, occasionally ten, particularly in the final weeks. It costs some little yield and buys a more clearer end. A listing that uses “equatorial” is telling you this in one word, and a grower who takes it as a note on geography misses the instruction inside it.

Foxtailing

The habit of some flowers to push out fresh bud clusters on top of old ones, giving spired, open buds rather than dense ones. In the majority of tent-bred strains it is a heat symptom, typically from light that is too close or a room that is too high, and the advice is to fix the room.

In many sativas, especially Southeast Asian and certain Haze hybrids, it is built in and will occur in a perfect room. A new sativa grower frequently wastes a month chasing a fault that is not a problem, dropping lights and heat only delaying a slow flower further. The listing seldom warns which type you should expect; the parentage usually tells you.
