The Autoflower Calendar: Seed to Harvest in eleven Weeks

Along the rivers in southern Siberia there is a scrappy little cannabis plant that nobody bothered to cultivate for most of history. It blooms whether the days are long or short, because where it lives the summer is too short to wait for a signal from the sun. That plant is Cannabis ruderalis, and almost every autoflower seed sold today owes its impatient internal clock to it. Breeders crossed ruderalis into modern indica and sativa lines, and after several decades of refinement the result is a seed that completes its whole life on a fixed schedule. Shops 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 walks through a typical autoflower grow one week at a time, from the moment you choose the pack to the day you chop the plant, with the decisions that count at each stage and the mistakes that cannot be undone later.

The Grow Starts at Checkout

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

• Total cycle length. Autoflower breeders quote time from seed, not from flip. A figure of eight weeks means eight weeks of life, and that covers germination.
• Height range. Autos range from forty centimetres to well over a metre. Fit the strain to the space you have, because there is no chance to keep the plant small by delaying flower.
• Generation. First-generation autos were small and rough; current releases are several generations on and far closer to their photoperiod parents. A new release from a known breeder is a safer bet than a bargain line of unknown age.

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

Days 1–7: Nothing to See, Everything Happening

The seed opens, a pale taproot appears, and within a few days two oval cotyledon leaves break through the surface. Nothing about this week looks impressive, but the root that forms now is the base for everything after it.

The one decision that matters most in week one is where the seed is planted. Autoflowers resent transplanting; a damaged root system at this stage costs days of growth that the plant cannot recover. Most growers start the seed straight in its final pot, or in a pot it will remain in. The medium should be light and only slightly moist; a seedling overwatered in a large wet pot is the commonest autoflower casualty of all.

Weeks Two and Three: The Only Window for Training

By the beginning of week two the plant is producing 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 begins.

Anything that bends the plant has to be done now, and it has to be light. Low-stress training, where branches are pulled sideways and held, works on most autos and spreads the canopy without checking growth. Cutting the main stem is more contentious: fast strains recover in days, others sacrifice a week they cannot afford. Stripping leaves at this stage is nearly always a mistake. If in doubt, leave the plant alone and settle for its natural shape; a somewhat untidy autoflower outyields a checked one.

Week Four: The Switch Nobody Flips

Somewhere between the third and start of the fifth week, tiny white pistils appear at the nodes and the plant begins to stretch. Nothing on the timer was changed; the clock made it. Here is the point that defines the autoflower: the grower is a spectator to the most important transition in the whole life.

Two things change in practice. Light can stay where it is, commonly eighteen to twenty hours a day for the whole run; there is no need to drop it to twelve, and doing so simply reduces the harvest. And feeding moves gradually away from nitrogen towards phosphorus and potassium. Slowly is the key word: an autoflower hit a hard flowering feed in week four often develops burnt leaf edges and slows. Light doses, stepped up week by week, fit a plant this size.

The Middle of the Run

The stretch continues for roughly two weeks and can nearly double the plant’s height, which is why the height range on the pack mattered in week zero. When it slows, flowers begin to stack and the grow settles into its single most productive phase.

• Water volume. The plant drinks far more than it did in week two. Pots that dry out between waterings in a day need a larger volume per watering, not more frequent light ones.
• Humidity. Tight autoflower buds on a plant this low sit close to moist soil; dropping relative humidity below fifty percent prevents mould before it starts.
• Support. Big colas on a thin stem bend by week seven. A stake placed now, rather than after the weight arrives, saves broken branches.

The Last Fortnight

The quoted cycle length is a median, not a contract. Individual plants from the same pack ripen a week either side, and environment push the figure further. The plant, not the pack, says when it is done.

The reliable signs: pistils turn from white to rust and retreat inward; the fan leaves yellow and drop as the plant pulls its reserves into the flowers; and under a loupe the resin glands change from clear to cloudy, with a proportion of amber. Harvesting at mostly cloudy with some amber heads is the conventional compromise; more amber means a heavier, sleepier result. Running plain water for the final week is commonly done and harmless, whatever the forums over its necessity says.

Errors Without a Reset Button

A photoperiod grower who stresses a plant can add a few weeks of veg and allow it catch up. An autoflower grower has no such option; the clock goes on running. These are the mistakes that surface in harvest weight every time.

• Overwatering a seedling in a large pot. The root stands in saturated medium, stalls, and the plant flowers at a fraction 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 lost yield.
• Topping a slow or unknown strain. On the slow line it takes a week that the plant never gets back.
• Heavy feeding before week four. Autos are light feeders in the first weeks and burn easily; the setback lands exactly when the plant needs to be stretching.
• Transplanting after the first week. Each day of root repair is a day of flower lost.

The Point of a Schedule

All of the above sounds like a catalogue of limitations, and in one sense it is. But the preset clock is the feature that made autoflowers successful, not a defect to tolerate.

A grow that ends in eleven weeks regardless can be scheduled to the week: sow in April, harvest in June, start again. A balcony grower gets a plant that remains under the railing. Someone in a short-summer climate fits two season crops inside a window that permits only one photoperiod plant. A beginner grower sees the whole cycle in less than three months instead of six, and gets to make the next attempt that much earlier. Not one of those advantages needs a bigger harvest to justify it.

Ordering From Turbo Autoflower Seeds

Turbo Autoflower Seeds dispatches every order in plain packaging, with the breeder’s seed packs sealed inside and no indication of the contents on the outside parcel. Orders to the United States are not taken, as seed importation is not permitted there. Seed laws vary sharply 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 job, and nothing here is legal advice.
