The Hindu Kush, Explained Through a Seed Pack

Each quality that moves an indica seed was bred there by a range of mountains. The short frame, the fast flowering, the dense resinous buds, the wide blue-green leaf, the colour that appears as the nights turn cold: not one of them is a breeder’s invention. They are the solutions a population arrived at through many thousands of years to a particular combination of pressures, in great altitude, in a brief dry season, across the valleys of the Hindu Kush and the mountains beyond it. Modern breeding took that answer down the mountain and polished it, but the shape of the plant is to this day the shape of the terrain. The examples referred to in what follows come from the range at https://kushindicaseeds.com whose catalogue goes back to Afghanistan, northern Pakistan and the Indian Himalaya; the argument though holds to any true indica from any shop bank. Knowing the terrain is the most reliable way to understand the pack.

The Range

The Hindu Kush runs roughly eight hundred kilometres out of central Afghanistan into northern Pakistan, and the broader indica homeland spilling across into the western Himalaya on one side and the lowlands around the Central Asian interior to the other. The plant has been grown there over a very long time, chiefly for hashish, which means selected generation by generation by people who wanted a plant rather than anything else: resin that could be rubbed or sieved from a plant that would have ripened before the first frost.

That is a different history to the one that produced the equatorial sativas, in which seasons hardly vary and the plant could grow for most of a year. All that comes below is the consequence of four facts about the terrain: it is high, it is dry, its growing season is short, and the nights turn cold fast. The order that they are taken below hardly matter; a plant meets all of them in the same once.

Leaves for a Thin Atmosphere

An indica leaf is broad, thick and a deep green, with few broad lobes whereas a sativa fan leaf has more thin ones. Both things about the climate select for the broad shape. High-altitude air and hard sun mean a high photon dose per square centimetre, so a wide leaf catches plenty and does not need needing much surface; a big thin leaf would just scorch. And constant wind shreds fine leaves, while a thick, short-stalked leaf holds.

The dark colour is pigment loaded thickly into a heavy leaf, and part of the same adaptation. To the grower these leaves matter in a single everyday way: a dense indica canopy blocks light from everything beneath the top layer much more thoroughly than a sativa’s, which means lower buds on an unmanaged indica finish in small and loose. People that strip a large leaves in mid-flower are undoing, carefully, what the range did for thousands of years.

Height Is a Cost at Two Thousand Metres

Much of the traditional growing zone lies from a thousand five hundred and three thousand thousand metres. Up that height the air is thin, the UV exposure is heavy, the wind is relentless and every centimetre of stem over the ground takes water the plant can ill spare. A tall plant on such terrain dries out more, snaps sooner and gains nothing for its extra height, because there is no canopy to clear.

The plant that survived is compact: short internodes, a single dense main stem, branches kept close, often wider than it is tall. In a tent that carries over directly: a pure indica line gains maybe half its height again through flower where a sativa doubles, sits under a light at a modest gap and seldom requires tying at all. Growers short on little headroom choose indica for this trait, and it is the mountain, not the breeder, that they are relying on.

Anthocyanin and the Autumn

High-valley nights fall below ten degrees long before the days do, and a good number of indica lines respond to that chill by making anthocyanin, the same pigment that colours a maple leaves red. On the plant it appears as purple through the bracts, leaves and sometimes the stem, and it does nothing for the grower beyond look beautiful.

A thing worth take from it is a matter of lineage, not decorative. The tendency to colour is carried from specific cold-valley populations, and a line that purples reliably in a cold final two weeks has the origin whatever the name claims. Strains marketed as « purple » that will only colour under heavy cold, or not really, typically carry the word in the name and in the genes. Chilling the room in the last weeks draws the colour forward if it exists and does nothing at all if it does not; it also checks the finish, so it is a trade and not a free trick.

The Short Season: Why It Flowers Fast

At two thousand metres the frost-free season is short, while the autumn arrives quickly and decisively. A plant which took fourteen weeks to ripen after the days began to shorten did not make seed in such terrain, so the genes left the population. What stayed reacts sharply to the first shortening days and ripens in about seven to nine weeks from the signal.

In a tent that reflex is the single most frequently valued indica trait. Flip to twelve hours and the plant commits at once, grows for a couple of weeks and fills flower over the rest of a short cycle. The quickest lines at Kush Indica Seeds finish at around 7 weeks after the switch, which permits as many as five or six harvests a year from one room whereas a long sativa allows two. This speed is no cleverness on the breeder’s part; it is the first snow written into the plant’s calendar.

Dry Air: Why the Buds Are Dense and Resinous

The old zone is arid: thin humidity, intense sun, rare rain in the late summer. A plant there has two pressures that its resin answers at once. It must protect its flowering tissue from ultraviolet light, and it needs to hold moisture in the flower over a long stretch of dry wind. Trichomes does both: the resin heads block the ultraviolet and their waxy layer slows water loss. Farmers for hashish then pushed the resin even harder, because resin was the crop.

Dense flower structure belongs with the same cause: a closely clustered bud loses less water than an airy one in dry air. In a tent these two traits come as a pair, but just one of them is always welcome. The resin is. The density becomes a risk the instant the air is humid: a bud shaped to retain water in a desert holds it equally well in a damp tent, and bud rot spreads through a hard indica cola more quickly than in anything the equator ever made. The quality that sells the seed is the one that calls for a drier room during the last few weeks.

Reading the Place Names

Most indica seed names carry place places or descend from one, and the names are more informative than most buyers look. « Afghani » usually means a population from the Mazar-i-Sharif region, and the classic squat, hash-plant, early-finishing form. « Hindu Kush » on a listing refers to the central mountains itself and often to material taken on the eastern side. « Chitral » or « Mazar » name specific valleys with their own local types, the first frequently colouring and the latter heavy and late for an indica. Kush Indica Seeds gives the collection area on every line where it is documented, and that turns the name from a brand to a datum the grower can use.

Most indica packs on sale is hybrid stock several generations from the valley, bred for consistency rather than for the spread a pure landrace carries; a buyer that wants the spread has to look for packs labelled as pure reproductions and expect the surprises which come with the label.

Taking the Plant Off the Mountain

Every adaptation discussed above was a answer to a condition which a tent does not present, and a solution that has lost its problem does either of two ways: it becomes a cost-free advantage or it becomes a hazard. The speed and the short frame are advantages, because no condition in a room punishes a plant for them. The density and the heavy canopy are costs, since the dry wind that justified them is absent and the damp air of a sealed room has precisely the reverse influence.

This is why the indica grow succeeds or fails on one variable more than any other: humidity during the last three weeks. A person who holds it low gets the hard, frosted, early harvest the mountain built; one who does not is punished with mould in the thickest colas, which is exactly where the mountain had trying the plant to hold moisture in. Indoors, the mountain is to be reconstructed in the last two weeks: cool, dry, moving air. Everything that remains about running indica is forgiving precisely because the plant was selected for a place much harder.

Kush on the Label

The word that lent the range its name has since travelled a long way from it than any other in cannabis. « Kush » in a modern seed listing can refer to an true Hindu Kush landrace, a West Coast hybrid with one Afghan grandparent, or a line named Kush because the seller thought the sound of it. A famous OG Kush line, which dominates the appearances of the word in the market, is probably as much sativa-influenced than a good deal of the stock it takes the word from, while its growth habit, finishing time and leaf shape show as much much.

A usable rule is the same one that applies throughout this article: ignore the word and go back to the terrain. A listing which states a modest stretch, a flowering time under nine weeks, a dense flower and a wide leaf is describing a mountain plant whatever it is named; one that states a lanky habit, eleven weeks and airy flowers is describing a plant from somewhere else with a borrowed name. The seed remembers where it came by; the name frequently has forgotten.
