Each quality that sells an indica seed was put there by a range of mountains. The squat frame, the fast flowering, the hard frosted buds, the wide dark leaf, the colour that appears as the nights go cold: none of them is a breeder’s invention. They are the solutions a population arrived at over many thousands of years to a specific set of problems, in high altitude, in a short dry, cold summer, across the valleys of the Hindu Kush and the ranges around it. Modern breeding took that solution down the mountain and polished it, yet the logic of the plant is to this day the logic of the terrain. The examples referred to below come from the range at https://kushindicaseeds.com and its catalogue traces to Afghanistan, northern Pakistan and the Indian Himalaya; the argument itself applies to any true indica out of any shop catalogue. Knowing the terrain is the most reliable way to read the pack.
The Hindu Kush runs for about eight hundred kilometres out of central Afghanistan into northern Pakistan, with the broader indica homeland extending across to the western Himalaya on one side and the lowlands of the Afghan plateau to the other. Cannabis has been cultivated there over a very long time, mainly for hashish, which means selected generation after generation by farmers who wanted a plant rather than any other quality else: resin that could be sieved and pressed from a plant that would have ripened ahead of the autumn snow.
That is a different selection from the one that shaped the tropical sativas, where daylength barely change and the plant could grow for most of a year. All that comes below is a outcome of a handful of facts about the place: it is high, it is arid, the summer is short, and its nights turn cold fast. The sequence in which they are taken here hardly matter; a plant meets every one of them in the same once.
High-valley nights fall below ten degrees long before the days follow, and a good number of indica populations respond to that cold by producing anthocyanin, the same compound that colours a maple leaves purple. In the plant it appears as purple through the bracts, leaves and sometimes the stem, which it does little for the smoker except look striking.
The point to taking from the colour is a matter of lineage, rather than decorative. The capacity to turn is carried out of specific high-altitude stock, and a strain that purples every time with a cold final fortnight has the origin regardless of what the label claims. Lines marketed as «purple» that only turn with heavy cold, or not at all, usually carry the word in only the name and in the genes. Chilling the room during the final weeks brings the colour forward if it is present and achieves nothing at all if it is absent; it also checks ripening, so it is a trade and not a costless effect.
At two thousand metres the frost-free window is short, and the autumn comes quickly and hard. A plant that took fourteen weeks to finish after the days started to shorten never make seed in that terrain, and its genes dropped out of the population. The plant that remained reacts sharply to the first shortening days and finishes in about seven to nine weeks from the signal.
Indoors that response is the one most frequently cited indica trait. Switch to twelve hours and the plant moves immediately, stretches for a fortnight and stacks flower for the rest of a short cycle. The quickest strains at Kush Indica Seeds come in at around 7 weeks after the switch, and that permits five or six harvests a year from one room where a long sativa allows two. This speed is not efficiency on the breeder’s part; it is the first snow written into the plant’s own clock.
The old zone is dry: thin humidity, hard sun, rare rain in the flowering summer. A plant there has two problems that its resin answers together. It needs to shield its flowering tissue from UV exposure, and it needs to hold moisture inside the bud through weeks of desiccating wind. Trichomes do both: their heads absorb the ultraviolet and their waxy layer slows water loss. Selection for hashish then drove the resin further, because resin was the crop.
Tight bud structure goes to the same cause: a closely clustered bud loses less water than an open one in arid air. Inside a tent these same traits arrive together, but just one of them is unconditionally welcome. The resin is. The density turns into a risk the instant the room is humid: a bud built to retain water in a desert holds it just well in a damp room, and botrytis spreads through a hard indica cola more quickly than in anything the equator has ever made. The quality that sells the seed is the one that calls for a dehumidifier during the last three weeks.
Much of the traditional growing land lies from a thousand five hundred and three thousand metres. At at that height the air is thin, the ultraviolet load is intense, the wind is constant and every centimetre of stem over the soil takes resources the plant can ill spare. A tall plant in such terrain loses faster, snaps sooner and gains little for the extra height, because there is no canopy to clear.
The plant that persisted is compact: tight internodes, a strong dense main stem, branches kept close, often wider than it is tall. In a tent that translates straight: a true indica line stretches maybe half its height again in flower where a sativa doubles, fits beneath a light with a modest modest distance and seldom needs tying down. Growers with little headroom choose indica for precisely this reason, and it is the mountain, not the breeder, that those growers are thanking.
An indica leaf is wide, heavy and dark, and only a few broad fingers where a sativa fan leaf has more thin ones. Two pressures about the terrain select for that form. Thin air and hard sun put a heavy photon load per square centimetre, so a broad leaf gathers enough without needing much surface; a large thin leaf in that light simply burn. And steady wind tears fine leaves, while a thick, short-stalked leaf stays put.
The dark colour is pigment loaded thickly into a thick leaf, and part of the same adaptation. To the grower the features count in a single everyday way: a dense indica canopy blocks light from all growth below the top tier far more thoroughly than a sativa’s, which means lower buds of an untrained indica come in small and loose. Growers who remove a few large leaves in week three are reversing, carefully, what the range put there for thousands of years.
Most indica seed names carry the names of names or descend from them, and the places are far more informative than they realise. «Afghani» usually refers to stock out of the Mazar-i-Sharif of Afghanistan, which is a classic squat, hash-plant, early-finishing type. «Hindu Kush» on a listing points to the high range itself and frequently to material taken on the eastern side. «Chitral» or «Mazar» point to specific valleys that have their own local types, the former often colouring and the latter heavy and late for an indica. Kush Indica Seeds gives the origin region on each line where it is documented, and that turns the name a brand to a datum the grower can plan around.
Almost all indica seed on sale are worked material many generations removed from the original collection, bred for consistency rather than for the spread of a true landrace carries; a buyer who wants the population itself needs to shop for lines described as pure landrace stock and expect the surprises that arrive with the label.
Every adaptation discussed above was an answer to the pressure which a tent does not present, and any trait without its pressure behaves either of two ways: it turns into a cost-free advantage or it turns into a hazard. The fast finish and the short stature are advantages, since no condition in a tent punishes a plant for them. The density and the broad canopy become hazards, because the arid wind that justified them is gone and the damp atmosphere of a sealed room has exactly the opposite effect.
This is why the indica grow succeeds or fails on one variable more than on any other: humidity during the final few weeks. A grower that keeps it down gets the hard, resinous, fast flower the mountain built; one that does not gets rot in the thickest colas, where exactly where the plant had trying the plant to keep water in. In a room, the mountain has to be reconstructed for the last two weeks: cool, dry, with moving air. All else about running indica is easy precisely because the population was selected to survive somewhere much harder.
The word that gave the mountains its name has travelled further from it than almost any other in cannabis. «Kush» in a modern seed name can refer to a true Hindu Kush reproduction, a West Coast hybrid carrying one Kush ancestor, or a strain named Kush since the breeder liked the sound of it. A OG Kush line, and this dominates the appearances of the word today, is probably as much sativa-leaning than a good deal of the plants it takes the name from, while its stretch, flowering time and leaf show as.
A practical reading is the same one which applies throughout this article: look past the word and go back to the terrain. A listing which gives a low stretch, a finishing time under nine weeks, a hard bud and a broad leaf is describing a mountain plant whatever it is named; one that gives a tall frame, eleven weeks and airy flowers is selling something somewhere else wearing a borrowed name. The seed remembers the place it was shaped by; the name frequently does not.
