Autoflower Seeds, Week by Week

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 in its home climate the summer is too short to wait for a signal from the sun. That plant is Cannabis ruderalis, and nearly every autoflower seed sold today carries its impatient internal clock to it. Breeders folded ruderalis into potent indica and sativa lines, and after a few decades of refinement the result is a seed that completes its whole life on a fixed schedule. Shops such as https://turboautoflowerseeds.com trade 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 choose the pack to the moment you chop the plant, with the decisions that matter at each stage and the errors that cannot be reversed later.

Week Zero: The Pack Decides Half the Outcome

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. Three things on the pack are worth a closer look.

• Height range. Autos run from forty centimetres to well over a metre. Fit the strain to the space available, because there is no opportunity to keep the plant small by delaying flower.
• Generation. First-generation autos were weak and harsh; modern releases are many generations removed and far closer to their photoperiod parents. A recent release from a serious breeder is a better bet than a bargain line of unknown age.
• Total cycle length. Autoflower breeders quote time from seed, not from flip. A figure of eight weeks means eight weeks of life, and that includes germination.

Each strain on Turbo Autoflower Seeds ships with a grow sheet that states the expected height, light preference and cycle length, which removes most of the guesswork at this stage.

Week One: The Taproot Sets the Pace

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

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

The Short Vegetative Sprint

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

Anything that shapes the plant has to happen now, and it has to be light. Tie-down training, where branches are pulled sideways and secured, is fine on most autos and spreads the canopy without slowing growth. Cutting the main stem is riskier: fast strains recover in days, others lose a week they cannot afford. Stripping leaves at this stage is nearly always a net loss. If in doubt, let the plant alone and settle for its natural shape; a somewhat untidy autoflower outyields a checked one.

The Plant Decides on Its Own

At some point between the end of the third and start of the fifth week, small white pistils show at the nodes and the plant begins to stretch. Nothing on the timer was changed; the clock did it. This is the point that defines the autoflower: the grower is a spectator to the most important transition in the plant’s life.

Two things change in practice. Light can remain where it is, commonly eighteen to twenty hours a day for the whole grow; there is no need to drop it to twelve, and doing so only shrinks the harvest. And feeding shifts gradually away from nitrogen towards phosphorus and potassium. Slowly is the key word: an autoflower hit a hard flowering feed in week four frequently shows burnt leaf edges and stalls. Light doses, increased week by week, suit a plant this small.

The Middle of the Run

The stretch lasts for roughly two weeks and can nearly double the plant’s height, and that is why the height range on the pack mattered in week zero. When it slows, flowers begin to fill out and the plant moves into its most productive phase.

• Support. Heavy colas on a thin stem lean by week seven. A stake placed now, before the weight arrives, avoids broken branches.
• Light distance. As the canopy climbs, raise the lamp to keep the same distance. Light stress at the top of a short plant costs the best flowers.
• Humidity. Dense autoflower buds on a plant this short sit close to damp soil; dropping relative humidity into the forties heads off mould before it starts.

Weeks Eight to ten: Reading the Finish

The advertised cycle length is a median, not a contract. Individual plants from the same pack finish a week apart, and conditions push the number further. The plant, not the pack, tells you when it is ready.

The usual indicators: pistils go from white to amber and curl inward; the lowest leaves yellow and fall as the plant pulls its reserves into the flowers; and under a loupe the resin glands shift from clear to cloudy, with a scattering of amber. Cutting at mostly cloudy with some amber heads is the standard target; more amber means a heavier, sleepier result. Running plain water for the final week is widely practised and harmless, regardless of what the debate over its necessity concludes.

Where Autoflower Grows Go Wrong

A photoperiod grower who stresses a plant can extend a few weeks of veg and let it recover. An autoflower grower has no such option; the clock goes on running. The following are the mistakes that surface in harvest weight every time.

• Heavy feeding before week four. Autos are small feeders early on and burn easily; the setback lands exactly when the plant should be building size.
• Topping a slow or untested strain. On the wrong line it costs a week that the plant never makes up.
• Cutting the light to twelve hours “because it is flowering”. The plant never needed the signal, and the lost hours convert straight into lost yield.
• Transplanting after the first week. Each day of root recovery 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 flowers at a fraction of its size.

What the Calendar Is Good For

All of the above sounds like a catalogue of constraints, and in one sense it is. Yet the fixed clock is the reason that makes autoflowers popular, rather than a defect to work around.

A run that ends in eleven weeks no matter what can be planned to the day: start in April, harvest in June, sow again. A balcony grower has a plant that stays below the railing. Someone in a short-summer climate fits two season crops inside a window that permits barely one photoperiod plant. A beginner grower sees the whole cycle in less than three months instead of six, and gets to make the second attempt sooner. None of those advantages needs a heavier harvest to be worth it.

Ordering From Turbo Autoflower Seeds

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