Why Indica Looks the Way It Does: The Mountain in the Seed

Each trait that moves an indica seed has been bred there by a range of mountains. The squat frame, the seven-to-nine-week flowering, the hard frosted flowers, the broad dark leaf, the colour that comes in when the nights turn cold: not one of them is a breeder’s design. They are the solutions a population found over many thousands of years to a particular combination of problems, at great altitude, in a brief dry, cold summer, on the slopes of the Hindu Kush and the ranges around it. Breeders carried that solution down the mountain and refined it, yet the logic of the plant is to this day the logic of the place. The lines referred to in what follows come from the range at https://kushindicaseeds.com and its stock traces to Afghanistan, northern Pakistan and the Indian Himalaya; the argument though applies for any true indica out of any shop bank. Knowing the terrain turns out to be the quickest way to understand the pack.

A Dry Corner of Central Asia

The Hindu Kush runs for about eight hundred kilometres from central Afghanistan towards northern Pakistan, with the wider indica homeland extending over to the western Himalaya on one side and the lowlands of the Afghan plateau to the other. Cannabis has been grown there for centuries, mainly for hashish, and selected year by year by farmers who needed resin rather than any other quality else: resin that could be rubbed or pressed off a plant that had ripened ahead of the first frost.

That is a separate selection from the one that shaped the equatorial sativas, in which seasons barely vary and the plant was free to flower for half a year. Everything that comes below is the outcome of a handful of conditions about the terrain: it is high, it is arid, the summer is short, and the nights go cold fast. The order in which they are discussed below hardly matter; a plant experiences every one of them at once.

Cold Nights: Why Some Go Purple

High-valley nights drop below ten degrees long before the afternoons do, and many indica lines respond to the chill by producing anthocyanin, the same pigment that turns a maple leaf purple. On the plant it appears as purple through the bracts, leaves and sometimes the stem, and it offers nothing for the grower beyond looking striking.

A thing to taking from it is genetic, not cosmetic. The tendency to turn is carried out of specific cold-valley stock, and a line that purples reliably with a cool last fortnight carries the ancestry whatever the name claims. Lines sold as “purple” that will only colour with heavy cold, or not really, usually carry the colour in only the name and not in the plant. Chilling the room in the final weeks brings the colour out where it exists and does nothing at all if it is absent; it also slows the finish, so it is a trade and not a costless effect.

Leaves for a Thin Atmosphere

The indica leaf is wide, heavy and dark, with only a few broad lobes where a sativa leaf carries many narrow ones. Two things about the climate favour the broad form. High-altitude air and hard sun put a heavy photon dose on each square centimetre, and a wide leaf catches plenty and does not need much area; a big narrow-fingered leaf in that light simply scorch. And steady wind shreds fine leaves, while a stout, short-petioled leaf stays put.

The deep colour is pigment packed thickly into a thick leaf, and one part of the same adaptation. To the grower the leaves count in a single everyday way: a broad-leafed indica canopy shades all growth below the top tier much more completely than a sativa’s, so lower buds on an unmanaged indica come in small and loose. People that strip a few large leaves at mid-flower are reversing, a little, something the mountain put there for many thousands of years.

Seven Weeks Before the Snow

At two thousand metres the frost-free window is short, and the autumn comes early and decisively. A plant which took fourteen weeks to finish after the days began to shorten did not set seed in that ground, so its genes dropped out of the population. The plant that remained reacts fast to the first shortening days and ripens in roughly seven to nine weeks after that cue.

Indoors that reflex is the single most frequently valued indica trait. Flip to twelve hours and the plant moves immediately, stretches over a fortnight and fills flower over the remainder of a brief cycle. The fastest lines at Kush Indica Seeds finish in around 7 weeks after the flip, which permits as many as five or six harvests a year out of one room where a long sativa gives perhaps two. That difference is no efficiency on the breeder’s side; it is the snowline written into the plant’s clock.

Height Is a Cost at Two Thousand Metres

Much of the old growing land sits between a thousand five hundred and three thousand thousand metres. At at that height the air is thin, the ultraviolet load is intense, the wind is constant and every centimetre of stem above the soil takes water the plant cannot spare. A tall plant on such ground loses more, snaps sooner and gets nothing for its height, since there is no canopy it needs to outgrow.

The plant that persisted is compact: tight internodes, a strong dense main stem, side branches held close, often wider than it is tall. In a tent that translates directly: a true indica line gains maybe half its height again in flower where a sativa doubles, sits beneath a light with a modest modest distance and rarely requires training down. Anyone with little headroom buy indica for this trait, and it is the mountain, not the breeder, that they are relying on.

Resin as Sunscreen and Sealant

The traditional homeland is arid: thin humidity, hard sun, rare rainfall through the flowering summer. A plant there has two problems that resin answers at once. It must protect its flowering tissue from UV exposure, and it needs to hold water in the bud through a long stretch of desiccating wind. Trichomes does both: the heads absorb the ultraviolet and the waxy layer slows moisture loss. Selection for hashish then drove the trait further, since resin was the product.

Dense bud form goes with the same cause: a closely packed bud gives up less water than an open one in dry air. In a tent these same qualities come together, and only one of them is unconditionally an advantage. The resin is. The density turns into a liability the instant the air is damp: a bud built to hold water in a desert retains it just well in a wet tent, and bud rot spreads through a hard indica cola more quickly than through anything an equator has ever produced. The quality that sells the seed is the one that needs a drier room during the final few weeks.

Reading the Place Names

Most indica pack names are the names of names or derive from one, and the names are far more useful than they realise. “Afghani” usually refers to a population out of the north of Afghanistan, which is the typical short, hash-plant, fast-finishing type. “Hindu Kush” on a name refers to the high mountains itself and often to stock taken on the eastern side. “Chitral” and “Mazar” name particular valleys that have their own recognisable types, the former often colouring and the latter heavy and slower for an indica. Kush Indica Seeds lists the origin area on each pack whenever it is known, which turns the name from a brand to a datum the grower can use.

Most indica seed on sale is worked material many generations from the original collection, bred for uniformity and not for the variation of a true landrace holds; a buyer that is after the population itself has to look for lines labelled as unselected landrace stock and accept the variation which come with the label.

Taking the Plant Off the Mountain

Every trait discussed above was an answer to the condition that a tent does not impose, and any trait without its problem behaves one of two things: it turns into a free bonus or it becomes a cost. The speed and the low frame become advantages, because nothing in a tent penalises a plant for them. The density and the heavy leaf become costs, since the arid wind that justified them is gone and the still atmosphere of a closed room does exactly the opposite influence.

This is why the indica grow goes well or fails on a single variable far more than any other: humidity in the final few weeks. A grower who keeps it low gets the dense, frosted, fast flower the mountain bred; one that does not gets rot inside the best colas, where the the mountain had arranged hardest to hold water in. Indoors, the mountain has to be rebuilt in the last two weeks: cool, dry, with moving air. Everything that remains about growing indica is forgiving exactly since the plant was selected for somewhere hard.

Kush on the Label

The word that gave the range its name has moved further from it than any other in cannabis. “Kush” on a current seed name can refer to an unselected Hindu Kush reproduction, a Californian Coast hybrid with one Afghan grandparent, or a line called Kush because the seller liked the sound of it. The famous OG Kush line, which dominates the appearances of the word in the market, is most likely more sativa-leaning than many of the stock it borrows the name from, and its stretch, finishing time and leaf say as.

The practical rule is the one that holds throughout this page: look past the word and go back to the terrain. A listing that gives a low stretch, a finishing time below nine weeks, a dense flower and a broad leaf is describing a mountain plant regardless of what it is called; one that gives a tall habit, eleven weeks and open buds is describing a plant from somewhere else wearing a borrowed name. The seed remembers where it came by; the name frequently does not.
