Along the rivers in southern Siberia there is a scrappy little cannabis plant that nobody thought 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 owes its impatient internal clock to it. Breeders crossed ruderalis into potent indica and sativa lines, and after several decades of refinement 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 fastest line in its range finishes in around 56 days from sprout. This article follows a typical autoflower grow one week at a time, from the day you choose the pack to the day you chop the plant, including the decisions that matter at each stage and the mistakes that cannot be undone later.
Week Zero: The Pack Decides Half the Outcome
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 bears more weight. Three things on the pack deserve a second look.
- Height range. Autos range from forty centimetres to well over a metre. Fit the strain to the space available, because there is no opportunity to hold the plant small by delaying flower.
- Generation. Older autos were small and rough; modern releases are several generations on and far closer to their photoperiod parents. A recent release from a serious breeder is a better bet than a discount line of unknown age.
- Light tolerance. Some lines are selected for twenty hours light and repay it with bigger yields; others do better at eighteen. The breeder’s note is worth following.
- Total cycle length. Autoflower breeders state time from seed, not from flip. A number of eight weeks refers to eight weeks of life, and that covers germination.
Each strain on Turbo Autoflower Seeds comes with a strain guide that states the expected height, light preference and cycle length, which removes most of the guesswork at this stage.
The Quiet First Week
The seed cracks, a pale taproot appears, and within a few days two oval cotyledon leaves push through the surface. Little about this week looks impressive, but the root that forms now is the foundation for everything after it.
The single decision that matters most in week one is where the seed is planted. Autoflowers dislike transplanting; a disturbed root system at this stage costs days of growth that the plant cannot recover. Experienced growers germinate the seed straight in its final pot, or in a pot it will stay in. The medium should be light and only lightly moist; a seedling overwatered in a big wet pot is the commonest autoflower casualty of all.
Fourteen Days of Leaves
By the beginning of week two the plant is producing true leaves and adding size quickly. This is the closest thing an autoflower has to a vegetative stage, and it is finished almost before it starts.
Anything that bends the plant has to be done now, and it has to be light. Tie-down training, where branches are pulled sideways and held, works on most autos and spreads the canopy without checking growth. Topping is more contentious: some strains recover in days, slower ones lose a week they do not have. Stripping leaves at this stage is almost always a mistake. If in doubt, leave the plant be and accept 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 fifth week, tiny white pistils appear at the nodes and the plant starts to stretch. Nothing on the timer was changed; the clock made it. Here is the moment that separates the autoflower: the grower is a spectator to the most important transition in the plant’s life.
Two things shift in practice. Light can stay where it is, commonly eighteen to twenty hours a day for the whole run; there is no reason to drop it to twelve, and doing so only shrinks the harvest. And feeding moves slowly away from nitrogen towards phosphorus and potassium. Gradually is the key word: an autoflower given a sudden bloom feed in week four often shows burnt leaf edges and stalls. Small doses, increased week by week, suit a plant this small.
Weeks Five to Seven: Stretch, Then Stack
The stretch lasts for about two weeks and can nearly double the plant’s height, and that is why the height range on the pack was worth reading in week zero. When it stops, flowers begin to stack and the plant moves into its most productive phase.
- Humidity. Dense autoflower buds on a plant this low stay close to moist soil; dropping relative humidity below fifty percent heads off mould before it starts.
- Support. Heavy colas on a slender stem lean by week seven. A stake put in now, before the weight arrives, avoids snapped branches.
- Water volume. The plant uses far more than it did in week two. Pots that go dry between waterings in a day need a larger volume per watering, not more frequent light ones.
Knowing When to Stop
The advertised cycle length is a median, not a deadline. Individual plants from the same pack finish a week either side, and environment stretch the figure further. The plant, not the calendar, says when it is done.
The reliable signs: pistils turn from white to rust and curl inward; the fan leaves yellow and fall as the plant draws 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, more sedative result. Running plain water for the final week is widely practised and harmless, regardless of what the forums over its value says.
Where Autoflower Grows Go Wrong
A photoperiod grower who stresses a plant can extend a few weeks of veg and let it catch up. An autoflower grower cannot; the clock goes on running. The following are the mistakes that surface in harvest size every time.
- Overwatering a seedling in a large pot. The root stands in saturated medium, stops, and the plant flowers at a third of its size.
- Heavy feeding before week four. Autos are light feeders in the first weeks and burn easily; the setback 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.
- Topping a slow or unknown strain. On the slow line it costs a week the plant never makes up.
- Cutting the light to twelve hours “because it is flowering”. The plant did not need the signal, and the missing hours convert straight into smaller yield.
What the Calendar Is Good For
Everything above reads like a catalogue of constraints, and in one sense it is. Yet the preset clock is the feature that makes autoflowers popular, rather than a defect to work around.
A run that finishes in ten weeks regardless can be planned to the day: sow in April, cut in June, start again. A balcony grower has a plant that stays below the railing. A grower in a northern climate fits two outdoor crops into a window that permits barely one photoperiod plant. A beginner grower sees the whole cycle in under three months instead of six, and gets to make the next attempt sooner. None of those benefits requires a heavier harvest to justify it.
Ordering From Turbo Autoflower Seeds
Turbo Autoflower Seeds sends every order in unmarked 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 accepted, as seed import is restricted there. Seed laws vary widely by country, and in many places buying seeds is legal while germinating them is not; checking the rules where you live is the buyer’s job, and nothing in this article is legal advice.
