Along the rivers in southern Siberia there is a scrappy little cannabis plant that nobody thought 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 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. Specialist sellers 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 walks through a typical autoflower grow week by week, from the moment you choose the pack to the moment 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 rescued by a longer vegetative stage, so the room for error is smaller 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 number of eight weeks refers to eight weeks of life, and that covers germination.
- Generation. First-generation autos were small and harsh; modern releases are several generations on and far closer to their photoperiod parents. A recent release from a known breeder is a better bet than a discount line of unknown age.
- Height range. Autos run from forty centimetres to well over a metre. Match the strain to the space you have, because there is no opportunity to keep the plant small by delaying flower.
- Light tolerance. Some lines are selected for twenty hours light and repay it with heavier yields; others perform better at eighteen. The breeder’s recommendation is worth following.
Each strain on Turbo Autoflower Seeds ships with a grow sheet that states the tested 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 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 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. Experienced growers start the seed directly in its final pot, or at least in a container it will remain in. The medium should be airy and only lightly damp; a seedling drowned in a big wet pot is the commonest autoflower loss of all.
Fourteen Days of Leaves
By the beginning of week two the plant is producing true leaves and gaining size fast. This is the closest thing an autoflower has to a vegetative stage, and it is finished almost before it begins.
Anything that bends the plant has to happen now, and it has to be light. Low-stress training, where branches are pulled sideways and secured, works on most autos and opens the canopy without slowing growth. Topping is more contentious: some strains shrug it off, slower ones sacrifice a week they cannot afford. Stripping leaves at this stage is almost always a net loss. If in doubt, leave the plant alone and accept its natural shape; a slightly untidy autoflower outyields a stressed one.
The Plant Decides on Its Own
At some point between the third and start of the fifth week, small white pistils appear at the nodes and the plant starts to stretch. Nothing on the timer was changed; the genetics made it. This is the point that separates the autoflower: the grower is a spectator to the most important transition in the whole life.
Two things change in practice. Light can remain 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 shifts gradually away from nitrogen towards phosphorus and potassium. Gradually is the key word: an autoflower given a sudden bloom feed in week four frequently develops burnt leaf edges and slows. Light doses, stepped up week by week, suit a plant this small.
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 begin to stack and the grow moves into its single most productive stretch.
- Water volume. The plant uses far more than it did in week two. Pots that dry out between waterings in a day need a bigger volume per watering, not more frequent light ones.
- Light distance. As the canopy rises, lift the lamp to hold the same distance. Light stress at the top of a short plant costs the best flowers.
- Support. Big colas on a slender stem lean by week seven. A ring placed now, rather than after the weight arrives, avoids broken branches.
- Humidity. Dense autoflower buds on a plant this short stay close to moist soil; bringing relative humidity into the forties prevents mould before it starts.
The Last Fortnight
The advertised cycle length is a median, not a contract. Single plants from the same pack ripen a week apart, and conditions push the number further. The plant, not the calendar, says when it is done.
The usual indicators: pistils turn from white to rust and retreat inward; the lowest leaves yellow and fall as the plant draws its resources 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 a few amber heads is the standard compromise; further amber gives a heavier, more sedative result. Flushing for the final week is widely practised and low-risk, regardless of what the forums about its necessity concludes.
Where Autoflower Grows Go Wrong
A photoperiod grower who damages a plant can add a few weeks of veg and allow it catch up. An autoflower grower cannot; the clock keeps running. The following are the mistakes that surface in harvest weight every time.
- Topping a slow or unknown strain. On the slow line it takes a week that the plant never makes up.
- Transplanting after the first week. Every 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 third of its size.
- Cutting the light to twelve hours « because it is flowering ». The plant did not need the signal, and the missing hours convert straight into lost yield.
What the Calendar Is Good For
All of the above sounds like a list of constraints, and in one sense it is. Yet the fixed clock is the reason that makes autoflowers successful, rather than a drawback to tolerate.
A grow that finishes in ten weeks no matter what can be planned to the day: start in April, cut in June, start again. A balcony grower gets a plant that stays below the railing. Someone in a short-summer climate fits two outdoor crops into a window that permits barely one photoperiod plant. A first-time grower learns the whole cycle in under three months instead of six, and makes the second attempt sooner. None of those advantages requires a bigger harvest to be worth it.
Practicalities
Turbo Autoflower Seeds dispatches every order in plain packaging, with the breeder’s seed packs sealed inside and no hint of the contents on the outside parcel. Orders to the United States are not accepted, as seed import is restricted 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 remains the buyer’s responsibility, and nothing in this article is legal advice.
