About Silverfalls Kush Auto
Days 1 to 14, seed to fourth node: Expect Silverfalls Kush to crack in roughly 48 hours on damp paper towel and to break soil by day three. Growth is even and unhurried — four solid nodes by day 14, spaced somewhere between the two parent types. Damping off is rare if you hold near 70% humidity through this stage.
Weeks 3 to 6, building the frame: One top at node four and a light tie-down is all it asks for. Six leaders and an even canopy across roughly 70 x 70 cm, then it is ready to flip.
Bloom, weeks 1 to 65: The 40/60 character becomes obvious here. Limonene usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: up to 400 g/m2. Height: 80–120 cm. Tested at 15% THC. Difficulty: easy.
Bloom Through to Jar
Weeks 4 to 6. This is where the plant stops looking like a frame and starts looking like a crop. Development stays even across the bud sites, and the canopy work done in veg pays off now — eight comparable colas rather than one dominant top over a set of also-rans. Trichomes should be visible without magnification from about week four.
Weeks 63 to 65, ripening. Drop to plain water for the final ten days. The limonene carry gets strong enough that carbon filtration stops being optional in a residential street. Trichomes run clear to milky across the last fortnight, amber showing on sugar leaves before it reaches the calyxes; around 15% amber on the calyxes themselves is a common place to cut.
Drying and curing. Whole-plant hang in the dark at 17°C and 58% humidity for roughly 12 days — when stems snap instead of bending, it is ready for glass. Burp twice daily for the first fortnight, then once daily through weeks three and four. Finished weight should land near the up to 400 g/m2 estimate. The caryophyllene note comes through markedly stronger after curing than it did at harvest, which is the clearest evidence that a cure builds flavour rather than merely preserving it.
Difficulty: easy. In flower for 55-65 days. Stands 80–120 cm. Indoors it returns up to 400 g/m2. Outdoors, up to 400 g/plant a plant. Regular seeds with autoflowering genetics.
Aroma, Flavour and Effect
The first thing Silverfalls Kush does at 15% THC is lift it with a bright, nearly effervescent citrus. The relaxed, happy, euphoric effects follow within minutes, across head and body at once. Thinking stays clear while muscle tension drains off, which leaves the dose as the deciding factor — light for the afternoon, heavier and it moves into the evening without a jolt. Caryophyllene sits underneath all of it, adding a grounding warmth that keeps the whole thing anchored.
The Aromatic Three
Leading with Limonene, then Caryophyllene, and Linalool underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, limonene leads. After three or four weeks in sealed glass at 16-18°C the linalool undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile linalool molecules are the first thing you lose.
Suitability and Recommendations
Who does well with Silverfalls Kush? People growing on flat balconies from Cape Town to Johannesburg. Smallholders after a fast outdoor crop. Indoor growers short on headroom. Autoflowering genetics run to their own clock, so there is no light schedule to hold, no worrying about light leaks, and harvest lands 10-12 weeks from germination whatever the season is doing. It is rated easy, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions.
