Sativa seeds arrive with more jargon around them than any other category of cannabis seed, and most of it means one thing to a botanist, another to a breeder and a third to the grower trying to make a decision in front of the pack. The disappointing sativa grow nearly always traces back to a word that was read in the wrong one of those senses: a flowering time taken as a fixed number, a “sativa-dominant” label read as a statement of effect, a landrace chosen as if it were a tent-bred hybrid. The entries below are written with the range at https:\/\/hazesativaseeds.com<\/a> open as reference, because it runs strongly towards the long-flowering end of the category and that is where the words matter most; the definitions though hold to any sativa seed from any seller. They are in no particular order, because none of them makes usable without the rest.<\/p>\n

Sativa-dominant<\/h2>\n

The marketing category and not a botanical one. It generally means that more of a hybrid’s parents were classed as sativa by whoever wrote the description, which sometimes means nothing more than a certain the buds are longer or the smell sharper than the that breeder’s indica-labelled lines.<\/p>\n

The effect people connect with the word, clear-headed instead of heavy, is driven far more by terpene profile and by cannabinoid balance than it is by ancestry, and a good number of “sativa-dominant” hybrids produce a heavy couch effect and a good number of the opposite stock deliver exactly the reverse. To a buyer the label is useful as a loose guide to growth habit, flowering time and stretch; as a guide to effect it is next to worthless unless accompanied by the terpene notes.<\/p>\n

Terpinolene<\/h2>\n

A terpene present in high proportion in many classic sativa lines and responsible for much of what growers mean as a “sativa” smell: green, woody, lemon and faintly floral all at once. It is volatile, lost easily through fast drying, and terpinolene fades more quickly during storage than the earthier terpenes which dominate indica-leaning lines.<\/p>\n

To a seed buyer the word does two things. Where a listing names terpinolene as the leading aromas, the line probably carries substantial Haze-era genetics whatever the label says. And where the grower 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 tastes of hay and no trace of what the pack described.<\/p>\n

Hermaphroditism in long-flowering lines<\/h2>\n

The production of pollen-bearing flowers on a female plant, typically towards the end in flower and frequently in response to stress. Every cannabis line has some tendency for do; long-flowering lines show it more, for a plain reason: sixteen weeks of flower is sixteen weeks of exposure for a timer leak, a heat spike or a missed watering to set it off, and a old plant has already waited past its natural end frequently produces a few desperate male flowers on its own as a last attempt to make seed.<\/p>\n

None of these makes a sativa strain unstable by course; it makes the room’s discipline count over longer. Light-tight tents, steady conditions and harvesting when the plant is ready and not two week later take away most of the problem. A listing that states a breeder tests parents for hermaphrodite traits is worth worth hearing for a long-flowering line than on any other category.<\/p>\n

Flowering time (and what it is counted from)<\/h2>\n

The figure of weeks from the onset of flowering and maturity, which is the one most frequently misunderstood figure on a sativa pack. For photoperiod seed it is measured from the day the light is cut to twelve hours, not from germination, so a “fourteen-week” sativa started after an ordinary vegetative period is a five-month plant. Breeders also quote the optimistic end of the range, since the longer end sells fewer seed.<\/p>\n

Sativa plants take everywhere from ten weeks to more than twenty, and the longest line in the Haze Sativa Seeds range is at about 16 weeks from the flip. The catalogue can be filtered by this figure, which is a sensible first step if you have a grower on a fixed schedule. A grower who allows four weeks to the figure the pack says is seldom disappointed.<\/p>\n

Landrace versus heirloom<\/h2>\n

A population of plants adapted through generations to a particular place by the local growers and climate alike, rather than by modern selection. Thai, Thai, Congolese and Oaxacan stock are the sativa examples. A landrace is variable, rather than a single plant: inside a pack the heights, flowering times and smells spread widely than any tent-bred hybrid, and that variation is the whole value of growing one.<\/p>\n

The trap is buying a landrace like a finished hybrid. It brings habits that make sense in an open field, including height that no tent can hold and a flowering clock set to a equatorial daylength most growers never offer. “Heirloom” in a listing usually refers to a landrace that has been grown out away from its origin for a number of generations, often with light selection for tent conditions; it is closer to usable but still far from a hybrid. A seller listing “landrace” without a origin region and a reproduction count is using the word loosely, and the pack should be priced accordingly.<\/p>\n

Equatorial<\/h2>\n

Refers to lines out of regions in which daylength barely varies through the year, which means that the plant does not evolved a sharp response to changing days. These lines frequently start flowering reluctantly under a standard twelve-hour schedule, because twelve hours is, to them, an ordinary day rather than a signal.<\/p>\n

The practical response, passed around between sativa growers over decades, is to shorten the light more: eleven hours, occasionally ten, especially in the final weeks. It loses some yield yield and gains a earlier clearer finish. A listing which says “equatorial” is telling you this with one word, and a grower who takes it as a note on origin misses the instruction inside it.<\/p>\n

Haze (the family, not the smell)<\/h2>\n

Originally a specific family of plants put together in coastal California from Colombian, Thai and South Indian parents, and later preserved and worked in the Netherlands. The Haze grows tall, branches sparsely, flowers for twelve sixteen weeks and carries a scent of incense, pine and something metallic that no line quite has.<\/p>\n

In its looser sense “Haze” is any cross that contains a share of that family, and today is most of the sativa-leaning catalogue. A listing which reads “Haze” without lineage may be mostly percent original old family or a small fraction of it, and the grow time follows the share, not the name. The working question is not “is it a Haze” but “how much, and via which parent”.<\/p>\n

Stretch<\/h2>\n

The surge of vertical growth which comes after the switch to flowering. Most tent-bred plants gain around half their height again; sativas routinely double, and some landrace lines triple. The stretch continues two to four weeks and cannot be halted once it has started, merely bent sideways by training.<\/p>\n

In tent terms, the stretch multiplier is the fact to read ahead of choosing when to switch. A sativa switched at sixty centimetres centimetres inside a two-metre tent is touching the lamp by week four of flower; one switched at thirty centimetres has room. People moving over from indica strains nearly always switch far too late the first time, and the lesson is written on the ceiling of the tent.<\/p>\n

Foxtailing (and when it is not a fault)<\/h2>\n

The tendency of some flowers to grow new calyx growth on top of old ones, producing towered, irregular buds instead of round ones. In most indica-leaning lines it is a heat symptom, usually from light too close or a room too high, and the standard response is to fix the cause.<\/p>\n

In a good number of sativas, above all Thai and certain Haze hybrids, it is built in and will happen under a flawless room. A new sativa grower often wastes a month chasing a fault that is a problem, dropping lights and temperatures and slowing an already slow flower further. The breeder rarely says which kind you should expect; the lineage generally does.<\/p>\n","protected":false},"excerpt":{"rendered":"
