How to Grow AK 47 Fast Version
AK 47 Fast Version is a sativa-dominant strain (65% sativa), a fast-flowering cross of AK 47 with an undisclosed hybrid to speed up the bloom. It carries a 19 to 22% THC level, a fruity, woody flavor, and an energetic, euphoric and uplifted effect. As a fast version it keeps photoperiod genetics but races through flowering, so you still flip it to 12/12 but finish sooner. This guide walks you through the whole grow, from germinating the seeds to the final cure.
It reaches 1.5 m, flowers in 8 to 10 weeks, and its fast genetics let it run across the season outdoors with a high yield. That speed, strong AK potency and forgiving nature are a big part of its appeal.

How to Germinate AK 47 Fast Version Seeds
A healthy harvest starts at germination. The paper towel method is hard to beat: fold the AK 47 Fast Version 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 two to five days.
Once the taproot is a few millimeters long, move each seed root-down about 1 cm deep into a small pot of light, airy medium. Keep it lightly moist rather than soaked, hold humidity around 65 to 70%, and give soft light while the first true leaves open. Its vigorous, forgiving genetics make for a strong seedling that is easy to get going, even on a first grow.
Starter tips
- Use plain, lightly pH-balanced water (pH 5.5 to 6.5) for the first week.
- Keep seedlings warm and humid, but never waterlogged.
- Hold off on nutrients until the second set of serrated leaves appears.
Growing AK 47 Fast Version in the Vegetative Stage
As a fast version it keeps photoperiod genetics, so you control the veg stage with the light schedule. Keep AK 47 Fast Version on 18 hours of light a day, aim for day temperatures of 68 to 79°F, and hold humidity around 50 to 60%. It suits a temperate climate, so steady, moderate conditions work in its favor. As a 65% sativa it grows into a lively, slightly stretchy plant, settling around 1.5 m with management.
Because it races through flowering, keep the veg stage a little shorter than usual and have the plant where you want it before the flip. Topping early and using low-stress training to spread the lower branches opens up the canopy, improves airflow, and keeps the stretchy sativa frame even. Because it is a forgiving, beginner-friendly plant, it bounces back well if your timing or training is not perfect.
Flowering and Buds of AK 47 Fast Version
Indoors, flip AK 47 Fast Version to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks thanks to its fast genetics. Outdoors its speed lets it finish across the season, even fitting more than one cycle in warm climates. As a sativa-dominant plant it forms long, resinous colas and reaches a high yield given room.
Through bloom, keep air moving and watch humidity so the buds stay dry and mold-free. The flowers build a sweet, fruity aroma over a dry, woody base, a bright profile with the resinous punch of its AK side.
At 19 to 22% THC it sits in the medium range, giving an energetic, euphoric and uplifted effect, a bright, upbeat feel that is genuinely strong, so pace yourself.
Common Problems and Pro Tips
AK 47 Fast Version is a forgiving, beginner-friendly grow, but its sativa stretch, fast pace and potency point to a few things worth watching.
- Mind the speed: because it flowers fast, train and shape it early, since you have less time to fix a tall or uneven canopy before buds set.
- Manage the stretch: as a 65% sativa it reaches for the light early in flower, so give it headroom and keep the canopy even.
- Mind the potency: at 19 to 22% THC it is strong, so pace yourself even though it grows easily.
Expert tip: with a fast finish, do not rush the back end. Train for an even canopy, and dry and cure slowly so the fruity, woody notes hold up.
Aroma, Flavor and Effects
The nose is bright and fruity: a sweet, ripe-fruit lift over a dry, woody base. It leans juicy yet grounded rather than sharp, a lively profile that matches its upbeat, energetic character.
The flavor follows the nose, sweet fruit with a woody finish on the exhale. On the effect side it is energetic, euphoric and uplifted, a bright, functional feel with a strong sativa lift. Because THC runs 19 to 22%, it hits harder than its easy grow suggests, so start low.
Dominant terpenes
AK 47 Fast Version carries a focused terpene profile built on five players. Limonene drives the bright, fruity lift at the heart of its flavor, Bisabolol adds a soft, sweet, chamomile-like warmth, and Caryophyllene a warm, peppery kick. Pinene brings a fresh, woody pine note, and Linalool a gentle floral sweetness. Together they frame the fruity, woody character the strain is known for, bright and juicy over a dry, woody base.
Nutrient Schedule
Treat the figures below as a starting map, not a rulebook. As a fast, high-yielding sativa AK 47 Fast Version is a willing feeder, so read the plant first: tip burn means back off, while pale, slow growth means it wants a little more. All values use EC.
| Stage | EC |
|---|---|
| Seedling | 0.4–0.6 |
| Growth | 0.8–1.2 |
| Early flower | 1.2–1.4 |
| Full flower | 1.4–1.6 |
| Flush | 0.0–0.4 |
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
AK 47 Fast Version builds a good coat of resin, so its trim is worth keeping rather than tossing. The sugar leaves you take off while manicuring hold trichomes and suit Ice Water Hash, where cold water and agitation separate the resin heads into a clean, solventless concentrate. Pressing that hash into rosin keeps the fruity, woody 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 AK 47 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. Indoors this lands 8 to 10 weeks after the flip, and outdoors its fast genetics bring it in across the season.
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: drying over 10 to 14 days protects the fruity, woody aromas 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 is where the sweet fruit and dry wood really come together, and it is the step most growers rush.
