The Autoflower Calendar: Seed to Harvest in eleven Weeks

Somewhere in central Siberia there is a scrappy little cannabis plant that nobody bothered to cultivate for most of history. It flowers whether the days are long or short, because where it lives the summer is too brief to wait for a signal from the sun. That plant is Cannabis ruderalis, and nearly every autoflower seed sold today carries its stubborn internal clock to it. Breeders crossed ruderalis into modern indica and sativa lines, and after a few decades of selection the result is a seed that completes its whole life on a fixed schedule. Specialist sellers such as https://turboautoflowerseeds.com deal in exactly that kind of seed, and the quickest line in its range is harvestable in around 56 days from sprout. This article follows a typical autoflower grow week by week, from the day you pick the pack to the day you chop the plant, including the decisions that count at each stage and the errors that cannot be undone later.

The Grow Starts at Checkout

An autoflower cannot be rescued by a longer vegetative stage, so the room for error is narrower than with a photoperiod plant and the choice of seed carries more weight. A handful of things on the pack deserve a second look.

• Height range. Autos run from forty centimetres to well over a metre. Match the strain to the space you have, because there is no chance to hold the plant small by delaying flower.
• Light tolerance. Some lines are selected for near-continuous light and repay it with heavier yields; others do better at eighteen. The breeder’s recommendation is not decorative.
• Total cycle length. Autoflower breeders quote time from seed, not from flip. A number of eight weeks refers to eight weeks of life, and that includes germination.
• Generation. First-generation autos were weak and harsh; modern releases are several generations on and much closer to their photoperiod parents. A new release from a known breeder is a safer bet than a bargain line of uncertain age.

Each strain on Turbo Autoflower Seeds comes with a strain guide that gives the tested height, light preference and cycle length, which takes away most of the guesswork at this stage.

The Quiet First Week

The seed cracks, a white taproot appears, and within a few days two round cotyledon leaves push through the surface. Nothing about this week looks impressive, but the root that develops now is the base for everything after it.

The one decision that counts most in week one is where the seed goes. Autoflowers resent transplanting; a disturbed root system at this stage costs days of growth that the plant cannot get back. Experienced growers start the seed directly in its final pot, or in a pot it will stay in. The medium should be light and only slightly damp; a seedling overwatered in a big wet pot is the commonest autoflower casualty of all.

The Short Vegetative Sprint

By the beginning of week two the plant is growing true leaves and gaining size fast. This is the nearest thing an autoflower has to a vegetative stage, and it is over almost before it starts.

Anything that bends the plant has to happen now, and it has to be gentle. Tie-down training, where branches are pulled sideways and held, works on most autos and spreads the canopy without checking growth. Topping is riskier: some strains recover in days, others lose a week they cannot afford. Defoliation at this stage is nearly always a mistake. If in doubt, let the plant alone and accept its natural shape; a somewhat untidy autoflower outyields a checked one.

When Preflowers Appear

Somewhere between the end of the third and fifth week, small white pistils show at the nodes and the plant starts to stretch. No timer was changed; the clock made it. Here is the point that defines the autoflower: the grower is a spectator to the single most important transition in the whole life.

Two things change in practice. Light can remain where it is, typically eighteen to twenty hours a day for the whole run; there is no need to cut it to twelve, and doing so simply reduces the harvest. And feeding shifts gradually away from nitrogen towards phosphorus and potassium. Slowly is the operative word: an autoflower hit a sudden bloom feed in week four often shows burnt tips and stalls. Small doses, stepped up week by week, suit a plant this size.

Where the Yield Is Made

The stretch lasts for about two weeks and can nearly double the plant’s height, which is why the height range on the pack was worth reading in week zero. When it slows, flowers start to fill out and the plant moves into its single most productive stretch.

• Support. Heavy colas on a thin stem bend by week seven. A stake placed now, before the weight arrives, saves snapped branches.
• Humidity. Dense autoflower buds on a plant this low stay close to moist soil; bringing relative humidity into the forties heads off mould before it starts.
• Water volume. The plant drinks far more than it did in week two. Pots that go dry between waterings in a day need a bigger volume per watering, not more regular small ones.

Weeks Eight to eleven: Reading the Finish

The quoted cycle length is a median, not a contract. Single plants from the same pack ripen a week apart, and environment push the number further. The plant, not the calendar, says when it is ready.

The usual indicators: pistils go from white to amber and curl inward; the fan leaves yellow and drop as the plant draws its reserves into the flowers; and under a loupe the resin glands shift from clear to cloudy, with a scattering of amber. Harvesting at mostly cloudy with a few amber heads is the conventional compromise; further amber gives a heavier, more sedative result. Flushing for the final week is widely done and harmless, whatever the forums about its necessity concludes.

The Mistakes That Cannot Be Undone

A photoperiod grower who stresses a plant can add a few weeks of veg and let it catch up. An autoflower grower has no such option; the clock keeps running. These are the mistakes that surface in harvest size without exception.

• Heavy feeding before week four. Autos are light feeders in the first weeks and scorch easily; the damage lands exactly when the plant should be building size.
• Transplanting after the first week. Every day of root repair is a day of flower that never comes.
• Overwatering a seedling in a large pot. The root sits in wet medium, stalls, and the plant blooms at a third of its size.
• Cutting the light to twelve hours “because it is flowering”. The plant never needed the signal, and the missing hours convert directly into smaller yield.

Who the Fixed Clock Suits

All of the above reads like a list of limitations, and in one sense it is. Yet the preset clock is the feature that made autoflowers popular, not a drawback to tolerate.

A run that finishes in ten weeks no matter what can be scheduled to the week: sow in April, harvest in June, sow again. A balcony grower has a plant that stays below the railing. A grower in a northern climate fits two season crops inside a window that permits barely one photoperiod plant. A first-time grower learns the whole cycle in less than three months instead of six, and makes the second attempt sooner. None of those benefits needs a bigger harvest to justify it.

How the Seeds Reach You

Turbo Autoflower Seeds sends every order in plain packaging, with the original seed packs sealed inside and no indication of the contents on the outer parcel. Orders to the United States are not accepted, as seed import is restricted there. Seed laws vary widely by country, and in many places buying seeds is permitted while germinating them is not; knowing the rules where you live is the buyer’s responsibility, and nothing in this article is legal advice.
