What the Words on a Sativa Seed Pack Really Mean

Sativa seeds come with more vocabulary around them than any other kind of cannabis seed, and most of it says one thing to a botanist, something else to a seed company and a third to the person standing in front of the pack. The failed sativa grow nearly always goes back to a word that was read in the wrong one of those senses: a flowering time read as a fixed number, a «sativa-dominant» tag read as a statement of effect, a landrace bought like it were a tent-bred hybrid. The entries below were written with the range at https://hazesativaseeds.com open for the concrete examples, because it leans strongly towards the long-flowering end of the category and that is where the vocabulary matter most; the meanings themselves hold to any sativa seed from any shop. They are given in no special order, because not one of them is sense on its own without the others.

Hermaphroditism in long-flowering lines

The production of pollen-bearing flowers on a female plant, typically late in flower and frequently in response to stress. Almost every cannabis population carries some capacity for do; long-flowering plants express it more, and the reason is a simple one: fourteen weeks of flower is fourteen weeks of opportunity for a light leak, a temperature spike or a missed watering that can trigger it going, and an plant that has already waited past its intended finish frequently throws a few desperate male flowers on its own as a final effort to set seed.

Not one of this means a sativa line weak by nature; it makes the grower’s discipline count over a longer stretch. A sealed tents, steady temperatures and cutting when the plant is done and not two weeks later take away the greater part of the risk. A listing that states a breeder tests parents for hermaphrodite tendency is worth worth hearing for a sativa than on any other category.

Flowering time (and what it is counted from)

The number of weeks from the onset of flowering and harvest, which is the one most frequently misread number on a sativa pack. With photoperiod seed it is measured from the day the light drops to twelve hours, not from sowing, so a «fourteen-week» sativa started with a ordinary vegetative period is a twenty-two-week plant. Breeders additionally give the optimistic end of the range, because the other end sells fewer seed.

Long-flowering lines take anywhere from ten weeks to more than twenty, and the slowest line in the Haze Sativa Seeds range comes in at about 16 weeks from the flip. The catalogue can be filtered by this number, which is a sensible first pass if you have a grower with a tight schedule. A grower who adds four weeks on top of the figure the pack says is rarely caught out.

Landrace

A population of plants adapted through centuries to one region by the local climate and climate alike, rather than by modern breeding. Thai, Thai, Malawian and Mexican stock are the classic sativa cases. A landrace is variable, rather than a one plant: inside a pack the flowering times, flowering times and smells range far more than a tent-bred line, and this spread is the whole value of keeping one.

The trap is buying a landrace like a finished hybrid. It brings traits that made sense in an open field, including a frame that no tent can contain and a flowering clock tuned to an daylength most growers never offer. «Heirloom» on a listing usually means a landrace that has been grown out somewhere over a number of generations, often with a degree of selection for indoor life; it is closer to manageable but still not uniform. A shop listing «landrace» that does not give a origin region and a generation count is using the word loosely, and the seeds should be priced accordingly.

Latitude

The single number that determines whether a sativa will ripen outdoors, and a number no pack prints. Long-flowering plants need a run of shortening days to continue late enough to let the plant finish; at northern latitudes the frost comes first, and the grower cuts an unripe plant in the end of October or else watches it to mould in November. The further south, in a northern hemisphere, the later the season runs, and Mediterranean or low-latitude growers are able to ripen plants that temperate growers never will.

The usable reading for a seed pack: an «outdoor» sativa harvest date is stated for the breeder’s home latitude, normally a point within temperate Europe or the west coast of the United States, and every degree north of it moves the finish later into the frost. A grower north of about the fiftieth parallel who is after a long-flowering sativa in the garden is shopping for an autoflower or a greenhouse, not a longer season.

Sativa-dominant

A marketing category rather than a botanical one. It usually indicates that more of a hybrid’s parents were described as sativa by whoever drafted the listing, and occasionally signals no more than a certain the buds are longer or the smell brighter than the same breeder’s indica-labelled lines.

The experience people connect with the word, clear-headed instead of heavy, is governed far more by terpene chemistry and by THC content than it is by the sativa fraction, and plenty of «sativa-dominant» releases deliver a heavy sleepy result while a good number of the opposite stock deliver the opposite. For a buyer the label is useful as a rough guide to growth habit, flowering time and stretch; as a predictor to how it feels it is next to worthless unless accompanied by the aroma description.

Terpinolene

A terpene present in large amounts in many old sativa lines and responsible for much of the thing growers describe as the «sativa» aroma: green, woody, citrus and faintly floral at once. It is fragile, lost easily by hot drying, and terpinolene fades faster during storage than the earthier terpenes which dominate indica-leaning stock.

To a seed buyer the word does two jobs. Where a listing names terpinolene as the lead aromas, the strain probably has substantial Haze-era ancestry regardless of what the label claims. And when the grower are after that smell to survive by the jar, the drying has to be slow and cool; a fast drying room flattens a terpinolene line into a flower that smells of very little and leaves no trace of what the pack promised.

Foxtailing

The tendency of some flowers to push out new bud growth on top of existing ones, giving spired, open buds instead of dense ones. In the majority of tent-bred strains it is a stress symptom, typically caused by light that is too close or temperatures that is too high, and the standard response is to correct the cause.

In many sativas, especially Thai and some Haze lines, it is genetic and will happen in a flawless room. A new sativa grower often wastes a month hunting a problem that is not there, lowering lights and temperatures only slowing an already long plant further. The breeder seldom says which type to expect; the parentage usually does.

Stretch (the doubling)

The surge of vertical growth which follows the change to flowering. Most tent-bred plants gain half again; sativas routinely double, and a few landrace types triple. The stretch continues three to five weeks and will not be halted after it begins, merely redirected by training.

In practical terms, a stretch multiplier is the fact to read ahead of deciding when to flip. A sativa flipped at sixty centimetres inside a standard tent is at the lamp by week four of flower; one flipped at thirty centimetres has room. Growers coming from indica strains nearly always flip far too late the first time, and the consequence is visible on the ceiling of the tent.

Haze

In its first sense a specific line of plants bred in coastal California from Mexican, Colombian and South Indian parents, and then preserved and worked in the Netherlands. The Haze runs tall, branches openly, flowers for twelve to sixteen weeks and carries a scent of spice, citrus and a note metallic that no other line quite reproduces.

In its looser sense «Haze» is any cross that carries a share of that family, and today is a great many of the sativa-leaning catalogue. A listing that reads «Haze» and gives no parents may be mostly percent original old family or one sixteenth of it, and the flowering time tracks the fraction, not the name. The useful question is not «is it a Haze» but «how much, and through which parent».
