SAD Fast Version Feminized Seeds · Sweet Seeds Ultra-Fast Indica · Sweet Afgani Delicious F1

SAD Fast Version by Sweet Seeds is a photoperiod-dependent, ultra-fast flowering feminized cannabis strain that guarantees top-tier Indica yields in record time.

Growing premium Indicas outdoors often means racing against the clock before the autumn rains arrive, leaving your dense buds vulnerable to mold and rot.

There is nothing more frustrating than spending months nurturing your plants, only to watch botrytis ruin your thickest colas just days before harvest. The stress of checking the weather forecast every morning and the anxiety of losing half your crop to humidity can turn a relaxing hobby into a nightmare.

SAD Fast Version eliminates that harvest anxiety by finishing its flowering cycle in just 6 to 7 weeks, allowing you to chop down heavy, resin-coated branches by early September, long before the bad weather hits.

Before growing SAD Fast Version

Prepare your space for a vigorous F1 hybrid that grows fast and demands a solid nutritional base. Whether you are setting up an indoor tent or preparing your outdoor guerrilla spot, having your soil and pots ready is crucial for this 90% Indica powerhouse.

• Choose 11–20 L (2.9–5.3 gal) pots for optimal root expansion.
• Prepare a well-aerated soil mix to prevent waterlogging.
• Set up your indoor timers for a standard 18/6 vegetative cycle.
• Ensure your carbon filter is ready, as the sweet Afghan aroma gets loud early on.

During cultivation

Once you flip the lights to 12/12 indoors, this strain shifts gears incredibly fast. You will notice rapid pistil development and a sudden burst of sweet, musky aromas filling your grow room. Because of its Black Domina heritage, the plant stays relatively compact but develops thick, heavy lateral branches that might need some support as the buds pack on weight.

Keep a close eye on your humidity levels during weeks 4 and 5 of flowering. Even though it finishes fast, those dense Indica nugs need good airflow to thrive. Defoliating the lower third of the plant will help direct all that explosive energy into the top colas, maximizing your final yield.

After: results and maintenance

When harvest day arrives in early September (or after 6-7 weeks indoors), you will be rewarded with rock-hard, frosty buds that reek of sweet musk and earthy Afghan hash. The trimming process is a breeze thanks to its high calyx-to-leaf ratio, saving you hours of sticky scissor work.

After a proper 2-week cure, the terpene profile matures into a mouth-watering candy-like sweetness. Maintenance of your grow space is minimal post-harvest, just a quick wipe down of your tent and a fresh carbon filter for the next run, as this strain leaves a lingering, delicious scent behind.

Short- and long-term advantages and benefits

• Because it flowers in just 6-7 weeks, you can harvest before autumn rains, which means you avoid bud rot and secure your crop safely.
• Thanks to its 90% Indica dominance, you enjoy a deeply relaxing body effect, which means it is the perfect smoke to chill out after a long day.
• Because it yields up to 500 g/m² (1.64 oz/ft²), you get a massive return on your indoor space, which means fewer runs to fill your stash jars.
• Thanks to its F1 hybrid vigor, the plants grow strong and resilient, which means less stress for you and a more forgiving grow cycle.
• Because of its sweet, musky terpene profile, every hit tastes like premium Afghan hash, which means a top-tier sensory experience every time you roll up.

Get ready for a lightning-fast Indica that thrives in both indoor tents and sunny outdoor spots.

• Use 11–20 L (2.9–5.3 gal) pots for photoperiod growth.
• Keep germination temps around 22–25 °C (71–77 °F).
• For a hassle-free start, Clonex Pro Start Rooting Nutrient Solution speeds up rooting.

Vegetative Stage

Maintain an 18/6 light cycle and build a strong structure before the quick flip.

• Keep humidity around 50–60% for optimal transpiration.
• Apply gentle LST to open up the dense Indica canopy.
• Feed a balanced nitrogen base to support thick stems.

Flowering Phase

Switch to 12/12 indoors and watch the explosive bud development over just 6–7 weeks.

• Lower humidity to 40–50% to protect dense colas.
• Ensure strong airflow through the lower branches.
• At the end of flowering, OG Organics Big Bud Advanced Nutrients helps with density.

Harvest & Curing

Chop in early September outdoors or when trichomes hit your desired milky/amber ratio.

• Flush the substrate 7–10 days before chopping.
• Dry slowly at 18–22 °C (64–71 °F) for 10-14 days.
• Cure in glass jars for at least 2 weeks.

Personal Experience of Pevgrow’s CEO (Alan)

Whenever I want to secure a top-quality Indica stash without the long wait, SAD Fast Version is one of my go-to choices. Before popping these seeds, I always make sure my indoor setup is dialed in for a fast transition. I usually veg them for about 3 to 4 weeks in 11 L (2.9 gal) pots, topping them once to encourage a more even canopy.

During the grow, the sheer speed of this F1 hybrid always blows my mind. By week 3 of flowering, the resin production is already off the charts, and the sweet, earthy Afghan smell takes over the room. I highly recommend keeping your humidity strictly under 50% during the final weeks; those buds get incredibly dense, and you don't want to risk any mold.

After harvest, the results speak for themselves. The buds are rock-solid and sticky as glue. I love vaping this strain after a long day at the office—it melts away the stress instantly and leaves a delicious, sweet hash taste on the palate. It’s a bulletproof genetic that never disappoints.
