Indica Seeds: Every Trait Has an Altitude

Every trait that sells an indica seed has been bred there by a range of mountains. The short frame, the fast flowering, the dense resinous flowers, the broad blue-green leaf, the colour that comes in when the nights go cold: none of them is a breeder’s invention. They are the answers a plant arrived at through many thousands of years to a particular set of problems, at high altitude, in a brief dry season, across the slopes of the Hindu Kush and the mountains around it. Breeders carried that solution down the mountain and polished it, yet the logic of the plant is still the shape of the terrain. The examples referred to below are drawn from the range at https://kushindicaseeds.com and its stock goes back to Afghanistan, northern Pakistan and the Indian Himalaya; the account itself applies to any genuine indica out of any seed bank. Reading the terrain turns out to be the most reliable way to understand the pack.

The Range

The Hindu Kush runs roughly eight hundred kilometres from central Afghanistan into northern Pakistan, with the wider indica zone extending over to the western Himalaya to one side and the lowlands around the Central Asian interior on the other. The plant has been grown there over a very long time, mainly for hashish, and selected year after generation by people who wanted a plant above anything else: something that could be sieved or sieved off a plant that had finished ahead of the autumn frost.

This is a different selection from the one that shaped the tropical sativas, in which daylength barely vary and the plant could grow for half a year. All that comes below is the consequence of four conditions about the place: it is high, it is arid, the growing season is short, and the nights go cold fast. The order in which they are taken below hardly matter; a plant experiences every one of them in the same season.

The Low Frame

Much of the traditional growing zone sits from fifteen hundred and three thousand thousand metres. Up that height the air is thin, the ultraviolet load is intense, the wind is constant and every centimetre of stem above the soil takes resources the plant cannot spare. A tall plant on that terrain dries out more, breaks more and gains little for its extra height, because there is no canopy to outgrow.

The population that persisted is low: short internodes, a strong dense central stem, side branches held close, frequently broader than it is tall. In a tent that carries over straight: a true indica line stretches perhaps half its height again through flower whereas a sativa doubles, sits beneath a lamp at a modest modest gap and rarely needs training at all. Growers short on little height choose indica for this trait, and it is the mountain, not the breeder, that they are thanking.

Leaves for a Thin Atmosphere

The indica fan leaf is wide, thick and a deep green, with few wide fingers whereas a sativa fan leaf has more narrow ones. Both things about the climate select for that form. High-altitude air and intense sun put an heavy photon dose per square centimetre, and a broad leaf gathers enough without a lot of surface; a big thin leaf would just scorch. And steady wind tears thin leaves, whereas a thick, short-petioled leaf stays put.

The dark colour is pigment loaded densely in a heavy leaf, which is part of the same adaptation. For the tent the leaves count in one everyday way: a dense indica canopy blocks light from all growth below the top tier far more thoroughly than a sativa’s, which means the lower flowers of an unmanaged indica finish in airy and loose. People that remove a few large leaves in week three are reversing, carefully, what the range put there over many thousands of years.

Seven Weeks Before the Snow

At two thousand metres the frost-free window is brief, while the autumn arrives early and comes hard. A plant which took fourteen weeks to finish from the days started to draw in did not make seed in that terrain, so the genes dropped out of the population. What remained reacts sharply to shortening days and ripens in about seven to nine weeks from that cue.

In a tent that response is the single most cited indica trait. Switch to twelve hours and the plant moves at once, grows for a fortnight and fills flower over the remainder of a short cycle. The quickest lines at Kush Indica Seeds finish in around 7 weeks from the switch, and that allows five or six cycles a year from one space whereas a long sativa allows perhaps two. That speed is no cleverness on the breeder’s part; it is the snowline encoded into the plant’s calendar.

The Colour of a Cold Valley

Mountain nights fall below ten degrees long before the afternoons follow, and a good number of indica populations react to that cold by making anthocyanin, the same compound that turns autumn leaf red. On the plant it shows as purple through the bracts, leaves and sometimes the stem, and it offers little for the smoker beyond looking beautiful.

The thing to taking from the colour is genetic, rather than cosmetic. The tendency to turn is inherited from particular cold-valley populations, and a strain that purples every time in a cool last two weeks has that ancestry regardless of what the name says. Strains marketed as “purple” that will only turn under heavy cold, or not at all, usually carry the word in the name and nothing of it in the plant. Chilling the room in the last weeks brings the colour forward where it exists and achieves nothing at all if it is absent; it at the same time slows the finish, so it is a bargain and not a free trick.

Resin as Sunscreen and Sealant

The old zone is arid: thin humidity, hard sun, little rainfall in the flowering season. A plant in such a place has two pressures which its resin solves at once. It must protect its flowering parts from ultraviolet exposure, and it must hold moisture in the bud through a long stretch of dry wind. Trichomes does both: the resin heads block UV and their coating slows moisture loss. Selection for hashish on top of that pushed the trait even harder, because resin was always the product.

Dense flower structure goes with the same cause: a tightly packed bud gives up less water than an airy one in arid air. In a tent those two traits come together, but just one of them is unconditionally an advantage. The resin is. The density becomes a risk the instant the air is damp: a bud built to retain water in a desert retains it equally as well in a damp room, and bud rot moves in a dense indica cola faster than in any flower the equator has ever produced. The quality that sells the seed is the same trait that calls for a drier room during the final three weeks.

Reading the Place Names

The great majority of indica seed labels are place names or derive from them, and the places are far more informative than they realise. “Afghani” generally refers to a population from the north region, and a typical squat, hash-plant, fast-finishing type. “Hindu Kush” on a name points to the central range proper and often to material taken on the Pakistani side. “Chitral” and “Mazar” name particular valleys with their own recognisable types, the first frequently colouring and the second large and late for an indica. Kush Indica Seeds gives the collection area for every line where it is known, and that turns the name a flavour into a datum the grower can plan around.

Almost all indica packs on sale is worked stock many generations from the original collection, selected for consistency rather than to preserve the variation of a pure landrace carries; a buyer who wants the population itself has to look for packs described as pure reproductions and expect the surprises which come with them.

Where the Adaptations Turn Against You

Each adaptation described above was an answer to a pressure which a tent no longer present, and any solution without its problem behaves one of two ways: it becomes a cost-free bonus or it turns into a hazard. The fast finish and the short frame are advantages, because nothing in a room penalises them. The density and the broad canopy become costs, because the arid wind that justified them is absent and the damp atmosphere of a closed room has precisely the reverse effect.

This is why the indica cycle succeeds or goes wrong on a single factor far more than any other: humidity during the final few weeks. A person that holds it low gets the dense, resinous, early flower the mountain bred; one that lets it rise gets mould in the best colas, which is exactly where the mountain was trying hardest to keep water in. In a room, the mountain is to be reconstructed for the final fortnight: cool, dry, with moving air. Everything that remains about running indica is easy precisely because the plant was selected to survive somewhere much harder.

Kush on the Label

The word that lent the mountains its name has travelled a long way from it than any other in cannabis. “Kush” in a modern pack name can refer to a unselected Hindu Kush landrace, a West Coast hybrid carrying one Kush grandparent, or a line named Kush since the breeder thought the sound of it. A famous OG Kush family, which accounts for most of the use of the word today, is most likely more sativa-influenced than a good deal of the stock it takes the word from, and its stretch, finishing time and leaf shape say as much much.

A usable rule is the same one which applies across this article: look past the word and go back to the terrain. A listing which states an low stretch, a finishing time below nine weeks, a hard bud and a broad leaf is selling a mountain plant regardless of what it is called; one that states a tall frame, twelve weeks and airy buds is selling something else with a mountain name. The seed remembers the place it came by; the label often has forgotten.
