Indica Seeds: What the Mountains Bred In
Every quality that sells an indica seed has been bred there by a mountain. The squat stature, the fast flowering, the hard frosted flowers, the broad blue-green leaf, the purple that appears when the nights turn cold: none of them is a breeder’s invention. They are the answers a plant found through many thousands of years to a particular combination of problems, in great altitude, in a brief dry, cold season, across the valleys of the Hindu Kush and the ranges beyond it. Breeders carried that solution off the mountain and polished it, yet the logic of the plant is still the shape of the terrain. The lines pointed to in what follows come from the range at https://kushindicaseeds.com and its catalogue traces to Afghanistan, northern Pakistan and the Indian Himalaya; the argument itself holds for any true indica from any shop bank. Reading the terrain turns out to be the most reliable way to understand the pack.
The Range
The Hindu Kush runs for about eight hundred kilometres out of the middle of Afghanistan into northern Pakistan, with the wider indica homeland spilling across to the western Himalaya on one side and the deserts of the Afghan interior to the other. The plant has been cultivated there for centuries, chiefly for hashish, and chosen generation after year by farmers who wanted resin rather than anything else: something that could be sieved and pressed off a plant that had finished ahead of the first snow.
That is a separate history to the one that shaped the tropical sativas, where seasons barely change and the plant was free to grow for most of a year. All that follows is the outcome of a handful of facts about the terrain: it is high, it is arid, the summer is short, and its nights turn cold early. The sequence that they are discussed below does not matters; a plant meets every one of them at season.
Height Is a Cost at Two Thousand Metres
Much of the traditional growing zone lies from a thousand five hundred and three metres. At that height the air is thin, the ultraviolet load is heavy, the wind is relentless and each centimetre of stem above the ground takes water the plant cannot afford. A tall plant on such terrain dries out faster, breaks more and gets little for the extra height, since there is no canopy it needs to clear.
The plant that survived is compact: short internodes, a single thick central stem, branches kept close, often wider than it is tall. In a tent that translates straight: a pure indica line gains perhaps half its height again in flower where a sativa doubles, fits under a light at a short distance and rarely requires tying down. Growers short on limited headroom buy indica for this trait, and it is the mountain, not the breeder, that those growers are relying on.
Finishing Before the Frost
At two thousand metres the growing window is short, and the autumn comes early and hard. A plant which took fourteen weeks to finish from the days began to shorten did not make seed in such ground, and the genes left the population. What stayed responds sharply to shortening days and ripens in about seven to nine weeks from that cue.
In a tent that reflex is the one most frequently valued indica quality. Switch to twelve hours and the plant commits immediately, grows over a couple of weeks and stacks flower over the remainder of a brief run. The fastest lines at Kush Indica Seeds come in at around 7 weeks from the flip, and that permits five or six cycles a year from one room whereas a long sativa gives two. This speed is no cleverness on the breeder’s part; it is the snowline written into the plant’s calendar.
The Fat Leaf
An indica leaf is wide, thick and dark, and few broad fingers whereas a sativa fan leaf carries many narrow ones. Both things about the climate select for that form. Thin air and intense sun mean a high light dose on each square centimetre, and a wide leaf catches enough and does not need needing a lot of surface; a large thin leaf would simply burn. And constant wind shreds fine leaves, while a thick, short-petioled leaf holds.
The deep colour is pigment packed thickly in a heavy leaf, which is one part of the same answer. To the tent the leaves count in one everyday way: a dense indica canopy shades all growth beneath the top layer much more completely than a sativa’s, so the lower flowers of an untrained indica finish in airy and loose. People who strip a few few fan leaves in week three are reversing, carefully, something the mountain did for many thousands of years.
The Colour of a Cold Valley
High-valley nights fall under ten degrees long before the afternoons follow, and a good number of indica populations respond to the cold by producing anthocyanin, the same compound that colours a maple leaf purple. On the plant it appears as purple in the bracts, fan leaves and occasionally the stem, which it does little for the smoker except look striking.
A thing to take from it is genetic, not cosmetic. The capacity to colour is carried out of particular cold-valley stock, and a line that colours reliably in a cool last fortnight carries that origin whatever the name claims. Lines sold as “purple” that only colour under extreme cold, or never really, usually have the word in only the name and nothing of it in the plant. Chilling the room during the last weeks draws the colour out where it is present and achieves nothing at all where it does not; it also slows the finish, so it is a trade rather than a costless trick.
Built for a Desert Autumn
The old zone is arid: thin humidity, intense sun, little rain through the late summer. A plant in such a place has two problems that resin answers at once. It must protect its flowering parts from ultraviolet light, and it needs to keep water inside the flower over weeks of desiccating wind. Trichomes do both: their heads block UV and the coating reduces moisture loss. Farmers for hashish then drove the resin further, because resin was the product.
Dense flower structure goes to the same cause: a closely clustered bud loses less water than an airy one in arid air. In a tent those two traits come as a pair, and just one of them is unconditionally an advantage. The resin is. The density becomes a liability the moment the room is humid: a bud built to retain water in a desert holds it equally well in a damp room, and botrytis spreads through a dense indica cola more quickly than in anything the equator ever made. The quality that moves the seed is the same trait that calls for a dehumidifier during the last few weeks.
Afghani, Mazar, Chitral, Hindu Kush
Most indica pack labels carry place places or descend from them, and the places are far more informative than most buyers realise. “Afghani” generally refers to a population from the Mazar-i-Sharif of Afghanistan, and the classic squat, hash-plant, early-finishing type. “Hindu Kush” on a listing refers to the central mountains proper and often to material taken on the eastern side. “Chitral” and “Mazar” point to specific valleys with their own recognisable forms, the first frequently purpling and the second heavy and late for an indica. Kush Indica Seeds lists the origin region for each line whenever it is known, and that makes the name from a flavour to a fact the grower can use.
Most indica seed on sale are hybrid stock many generations removed from the original collection, bred for consistency rather than for the spread of a pure landrace carries; a buyer that is after the population itself needs to shop for lines labelled as pure landrace stock and expect the variation which come with the label.
Where the Adaptations Turn Against You
Every trait described above was a solution to a condition that a tent does not present, and a trait without its problem behaves one of two ways: it turns into a free bonus or it turns into a hazard. The fast finish and the short frame are bonuses, because nothing in a tent penalises them. The density and the heavy canopy are costs, since the dry wind that made sense of them is absent and the still air of a sealed room has exactly the opposite effect.
This is why the indica cycle goes well or goes wrong on one variable more than any other: humidity during the last few weeks. A person that keeps it down gets the hard, resinous, fast harvest the mountain built; one who does not is punished with mould inside the thickest colas, where exactly where the plant was trying the plant to hold water in. In a room, the terrain is to be rebuilt in the last two weeks: cool, dry, with moving air. All else about running indica is forgiving precisely because the population was selected for somewhere much harder.
What “Kush” Means Now
The word that gave the mountains its name has since travelled a long way from it than any other in cannabis. “Kush” in a current seed listing may mean an unselected Hindu Kush reproduction, a West Coast hybrid carrying one Afghan grandparent, or a strain named Kush since the breeder thought the sound would sell. A OG Kush family, which dominates the use of the word in the market, is most likely as much sativa-leaning than a good deal of the plants it borrows the word from, and its growth habit, flowering time and leaf say as much.
The practical rule is the one that applies throughout this article: ignore the word and go back to the terrain. A listing which states a low stretch, a finishing time below nine weeks, a dense flower and a broad leaf is selling a mountain plant regardless of what it is called; one that states a tall habit, eleven weeks and open flowers is describing a plant from somewhere else with a mountain name. The seed carries where it was shaped from; the name often does not.
