Indica Seeds: Every Trait Has an Altitude

Each quality that sells 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 blue-green leaf, the purple that comes in when the nights turn cold: none of these is a breeder’s design. They are the solutions a population found through many thousands of years to a particular set of problems, at great altitude, in a brief dry summer, on the slopes of the Hindu Kush and the mountains around it. Breeders took that answer off the mountain and polished it, but the logic of the plant is to this day the shape of the place. The examples referred to in what follows are drawn from the range at https://kushindicaseeds.com whose stock traces to Afghanistan, northern Pakistan and the Indian Himalaya; the account itself holds to any genuine indica out of any shop bank. Reading the terrain turns out to be the quickest way to understand the pack.

The Range

The Hindu Kush runs roughly eight hundred kilometres out of central Afghanistan towards northern Pakistan, with the wider indica homeland spilling over into the western Himalaya to one side and the deserts of the Afghan plateau to the other. The plant has been cultivated there for centuries, chiefly for hashish, which means selected year after generation by farmers who wanted a plant above any other quality else: something that could be rubbed or pressed from a plant that would have ripened before the first frost.

That is a separate selection from the one that produced the equatorial sativas, where seasons hardly vary and the plant was free to flower for most of a year. Everything that follows is the consequence of four conditions about the terrain: it is high, it is arid, the growing season is short, and the nights go cold fast. The sequence in which they are discussed here does not matter; a plant experiences every one of them at once.

Anthocyanin and the Autumn

Mountain nights drop below ten degrees weeks before the days follow, and many indica lines respond to the cold by making anthocyanin, the same pigment that colours autumn leaves purple. On the plant it appears as purple through the bracts, fan leaves and occasionally the stem, which it does nothing for the grower except looking beautiful.

The point to take from it is genetic, not decorative. The tendency to colour is carried from particular cold-valley populations, and a line that colours every time in a cool last two weeks carries the ancestry regardless of what the label says. Strains marketed as “purple” that only colour with heavy cold, or not at all, usually carry a word in only the name and nothing of it in the plant. Chilling the room in the final weeks brings the colour out if it is present and does nothing at all where it is absent; it also slows ripening, so it is a trade rather than a costless trick.

Altitude: Why the Plant Is Short

A good deal of the old growing zone lies from fifteen hundred and three thousand metres. Up that height the air is thin, the ultraviolet exposure is heavy, the wind is relentless and each centimetre of stem over the soil costs water the plant cannot spare. A tall plant on that ground loses more, snaps sooner and gains little for its extra height, because there is no canopy to clear.

The population which survived is compact: tight internodes, a single dense central stem, side branches held close, frequently broader than it is tall. In a tent that carries over straight: a true indica seed stretches perhaps half its height over through flower whereas a sativa doubles, fits under a light at a modest modest gap and seldom requires tying at all. Anyone with limited headroom choose indica for this reason, and it is the mountain, not the breeder, that those growers are thanking.

The Fat Leaf

The indica fan leaf is wide, thick and dark, and few broad fingers whereas a sativa fan leaf has many narrow ones. Both pressures about the terrain favour that form. Thin air and intense sun mean a high light load on each square centimetre, so a wide leaf catches enough and does not need needing a lot of surface; a large narrow-fingered leaf would just scorch. And steady wind tears fine foliage, while a thick, short-petioled leaf holds.

The deep colour is chlorophyll loaded thickly in a thick leaf, which is part of the same adaptation. To the tent the leaves count in a single practical respect: a dense indica canopy blocks light from all growth beneath the top tier far more thoroughly than a sativa’s, which means lower flowers on an untrained indica come in airy and weak. Growers that remove a fan leaves at week three are undoing, carefully, something the range put there over many thousands of years.

Resin as Sunscreen and Sealant

The old zone is dry: low humidity, hard sun, little rain in the late season. A plant there has two pressures that resin answers at once. It needs to protect its reproductive tissue from UV exposure, and it must hold moisture inside the flower through a long stretch of desiccating wind. Trichomes do both: the resin heads block UV and their coating slows moisture loss. Selection for hashish on top of that drove the resin even harder, because resin was always the product.

Dense flower form belongs with the same story: a closely packed bud loses less water than an airy one in dry air. In a tent those same traits arrive as a pair, and just one of them is unconditionally an advantage. The resin is. The density becomes a liability the instant the room is humid: a bud shaped to retain water in a desert retains it just as well in a wet tent, and botrytis moves in a hard indica cola faster than in anything the equator ever made. The quality that moves the seed is the one that needs a dehumidifier during the final three weeks.

The Short Season: Why It Flowers Fast

Above two thousand metres the frost-free window is brief, and the autumn arrives quickly and comes hard. A plant that took fourteen weeks to finish after the days started to shorten never set seed in such ground, so its genes left the population. What remained reacts sharply to the first shortening days and finishes in about seven to nine weeks from the signal.

Indoors that reflex is the one most frequently valued indica quality. Switch to twelve hours and the plant moves at once, grows for a couple of weeks and fills flower over the remainder of a brief cycle. The fastest lines at Kush Indica Seeds finish in about 7 weeks from the switch, and that permits as many as five or six cycles a year out of one space where a classic sativa gives perhaps two. This difference is no efficiency on the breeder’s side; it is the snowline written into the plant’s calendar.

The Valley Names on the Pack

The great majority of indica seed names carry place places or derive from one, and the places are more informative than they look. “Afghani” generally refers to stock from the Mazar-i-Sharif of Afghanistan, and the typical squat, hash-plant, fast-finishing type. “Hindu Kush” on a name points to the high range itself and often to material taken on the eastern side. “Chitral” and “Mazar” point to particular valleys with their own recognisable types, the former often purpling and the second heavy and slower for an indica. Kush Indica Seeds gives the collection area on each pack where it is documented, and that turns the name from a brand into a fact the grower can use.

Almost all indica seed on sale are hybrid stock many generations removed from the valley, selected for uniformity and not for the spread a true landrace carries; a buyer that wants the spread has to look for lines labelled as unselected reproductions and expect the variation which come with them.

What Changes in a Tent

Every adaptation described above was a answer to the condition which a tent does not impose, and a trait that has lost its pressure behaves either of two ways: it turns into a free bonus or it becomes a hazard. The speed and the low stature become bonuses, because no condition in a tent punishes a plant for them. The density and the heavy canopy are costs, because the dry air that justified them is absent and the damp atmosphere of a closed room has precisely the reverse influence.

This is why an indica grow goes well or goes wrong on one factor far more than on any other: humidity during the last three weeks. A person that holds it low is rewarded with the dense, frosted, fast flower the mountain built; one that does not gets mould in the thickest colas, where exactly where the mountain had arranged the plant to keep moisture in. In a room, the mountain has to be reconstructed for the final two weeks: cool, dry, with moving air. All else about running indica is forgiving precisely because the population was bred for a place hard.

Kush on the Label

The word that lent the mountains its name has moved further from it than almost any other in cannabis. “Kush” in a current pack name may refer to a true Hindu Kush landrace, a Californian Coast hybrid carrying one Afghan ancestor, or a strain called Kush because the breeder liked the sound would sell. A famous OG Kush family, which accounts for most of the appearances of the word in the market, is most likely as much sativa-influenced than many of the stock it borrows the name from, while its stretch, flowering time and leaf shape say as much.

A practical reading is the same one which applies across this page: ignore the word and read the terrain. A listing which states an low stretch, a finishing time below nine weeks, a dense flower and a wide leaf is selling a mountain plant regardless of what it is named; one that states a lanky habit, twelve weeks and airy flowers is selling a plant from else with a borrowed name. The seed remembers where it was shaped by; the name frequently does not.
