How to Grow White Widow x Ak47 Fast Version

White Widow x Ak47 Fast Version is a 70/30 indica-leaning Fast Version that pairs the frosty White Widow with the legendary AK47, plus a secret fast-flowering parent added for speed. It is a photoperiod plant, so you still flip it to flower, but it finishes quickly in 8 to 10 weeks, with earthy, herbal and woody flavors and THC from 16 to 20%. This guide covers the full grow, from germinating the seeds to the final cure.

At around 4.27 ft it stays manageable and still gives a high yield, and the fast flowering makes it a great pick for short seasons. If you want the standard, non-fast version, Blimburn also offers the feminized White AK 47, and for another quick finisher there is Somango Fast Version.

White Widow x Ak47 Fast Version at a Glance

Before you plant anything, it helps to see the full picture in one place. Here is the quick profile for this fast-flowering indica hybrid, taken straight from the strain’s grow data.

As the name says, this is a fast finisher, so it sits among the fast flowering seeds, and its 70% indica makeup places it with the indica seeds for growers who want a quick, relaxed, resinous crop.

How to Germinate White Widow x Ak47 Fast Version Seeds

A healthy harvest starts at germination. The paper towel method is hard to beat: fold the seeds inside two damp sheets, slide them between two plates, and keep them somewhere dark at 70 to 79°F. A taproot usually appears in one to five days.

Once the root is a few millimetres long, move each seed into its starter pot with the root pointing down and cover it with about 2 cm of soil. Keep the medium lightly moist, not soaked, and hold humidity around 65 to 70% while the first true leaves open. These are feminized seeds, so every plant will flower and there are no males to sort out.

Starter tips

• Use plain, lightly pH-balanced water (pH 5.5 to 6.5) for the first week.
• Give seedlings gentle light, not a full-power lamp pressed overhead.
• Hold off on nutrients until the second set of serrated leaves appears.

Growing White Widow x Ak47 Fast Version in the Vegetative Stage

Unlike an autoflower, a Fast Version is a photoperiod plant, so you control the timing: it stays in veg until you switch the light cycle, and then it flowers fast. That means you can top and train it just like any feminized photoperiod. It likes a temperate climate, so aim for day temperatures of 68 to 81°F and keep veg humidity in the 50 to 60% band, with an airy substrate of perlite, peat or coco coir.

Because it finishes fast, it is a smart choice for shorter US growing seasons:

• Pacific Northwest (Portland or Seattle): the quick finish lets it beat the autumn rains that catch slower photoperiod plants.
• New England (Vermont or Maine): a short season with early frost suits a Fast Version, which can ripen in time where a standard photoperiod might not.
• Upper Midwest (Michigan): warm summers give way to an early autumn, so the faster flowering helps it finish before the cold sets in.

At around 4.27 ft this is a compact, sturdy indica. Top it once it has five or six nodes and use low-stress training to spread the canopy and make the most of its high yield before you flip it into flower.

Flowering and Buds of White Widow x Ak47 Fast Version

Switch to a 12/12 light cycle and this Fast Version gets to work, finishing in 8 to 10 weeks, which is quicker than a standard photoperiod thanks to its fast-flowering parent. From there it frosts over with the dense, resin-rich buds you expect from White Widow and AK47 genetics.

Drop humidity to 40 to 45% during flower to protect the tight buds from rot, and keep airflow moving through the canopy. Outdoors, the quick finish is the whole point: you harvest earlier than a regular photoperiod, which is a real advantage in a short or wet season.

At a medium 16 to 20% THC it still lays down a thick trichome coat, so judge ripeness by the resin heads rather than the calendar.

Common Problems and Pro Tips

White Widow x Ak47 Fast Version is hardy and quick, but its dense, resinous buds mean a couple of things are worth watching.

• Mould in dense buds: the frosty White Widow trichome coat and tight indica structure trap moisture, so keep humidity down in flower and air moving against bud rot and powdery mildew.
• Pests: check leaf undersides weekly for spider mites, which like warm, dry rooms, and keep the grow space clean.
• Substrate and feeding: use an airy mix with perlite, peat or coco coir, and feed moderately, reading the plant rather than following a fixed dose.

Expert tip: a Fast Version gives you the best of both worlds, the control of a photoperiod with the speed of a fast finisher. Top and train it hard in veg, time the flip to suit your season, and you get an early, heavy harvest. Its frosty White Widow and AK47 resin also makes it a strong choice for hash and concentrates.

Aroma, Flavor and Effects

The nose is classic and grounded: earthy and woody with a herbal, slightly spicy edge. It reads old-school and savoury rather than sweet, and it sharpens as the buds cure in the jar.

The flavor follows, earthy and woody with that herbal note. On the effect side it is uplifting and energetic at first, then eases into a soothing, relaxed calm from its 70% indica side, which makes it a well-rounded, versatile smoke.

Terpene profile

Five terpenes shape this one. Caryophyllene brings a peppery, spicy kick; Limonene adds a bright citrus lift against the earthy base; Pinene drives a fresh, piney note; Linalool lends a soft floral touch; and Bisabolol rounds it out with a gentle, chamomile-like softness that plays into the soothing, herbal character. Together they frame the earthy, woody flavor.

Nutrient Schedule

Treat the figures below as a starting map, not a rulebook. White Widow x Ak47 Fast Version takes a moderate feed well, but read the plant first: tip burn means back off, while pale, slow growth means it wants a little more. All values use EC.

Keep the pH around 6.0 to 6.5 in soil and 5.5 to 6.0 in hydro so the roots can actually take up what you feed.

What to Do With Your Trim: Extracts and Hash

With White Widow and AK47 in its lineage, this Fast Version is a frosty, resin-rich plant, so its trim is prime material for concentrates. The sticky sugar leaves you take off while manicuring are loaded with trichomes and were practically made for Ice Water Hash, where cold water and agitation separate the resin heads into a clean, solventless concentrate. Pressing that hash into rosin keeps the earthy-herbal flavor intact, or you can run a solvent extraction if that is your setup. The bare stems will not extract, but chopped and composted they feed organic matter back into the soil for your next grow.

Harvesting, Drying and Curing White Widow x Ak47 Fast Version

Timing the harvest comes down to the trichomes. Grab a loupe and watch the heads turn from clear to milky white; a scattering of amber signals peak ripeness. Thanks to the fast flowering, that point comes early, at the end of the 8 to 10 week window indoors, and sooner than a standard photoperiod outdoors.

After the cut, hang the branches in a dark room at 59 to 68°F with humidity near 50% and gentle air movement. Slow beats fast here: drying over 10 to 14 days protects the earthy, herbal terpenes that define this strain. When the small stems snap instead of bending, move the buds into jars.

Cure in sealed glass, opening the jars daily for the first week to let moisture escape, then easing off as the aroma deepens. Two to four weeks of patience here turns a good harvest into a genuinely smooth one, and it is the step most first-time growers rush.
