About Crystal Feminised
Days 1 to 14, seed to fourth node: Expect Crystal to crack in roughly 48 hours on damp paper towel and to break soil by day three. Early growth comes in low and wide — broad seed leaves first, then the dark fan leaves the indica side is known for. Four nodes by the end of week two, stacked close together. Damping off is rare if you hold near 70% humidity through this stage.
Weeks 3 to 6, building the frame: Top at the fourth node and the laterals take over fast. A 60 x 60 cm footprint filled by week five is normal, still under 40 cm tall, which is what makes this workable in a small tent.
Bloom, weeks 1 to 10: The 66/34 character becomes obvious here. Linalool usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: 400-500 g/m2. Height: 150 cm. Tested at 21% THC. Difficulty: beginner.
Bloom Through to Jar
Weeks 4 to 6. This is where the plant stops looking like a frame and starts looking like a crop. Density climbs almost daily — by week five a developing cola should feel firm rather than springy under light pressure. Pull the fan leaves shading the lower canopy at the start of week four, which matters more than usual if the room is sitting near 55% humidity through a damp autumn.
Weeks 8 to 10, ripening. Drop to plain water for the final ten days. The linalool 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 400-500 g/m2 estimate. The myrcene 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: beginner. In flower for 8-10 weeks. Stands 150 cm. Indoors it returns 400-500 g/m2. Outdoors, 500 g/plant a plant. Feminised seeds.
What Crystal Is Like to Use
The effects most commonly reported for this cultivar are focused, calm. At 21% THC it sits in a bracket where the dose does most of the work. A single bowl vaporised at 185°C gives a manageable body relaxation with your head still intact — enough to close out a long day in the summer heat. Push the dose and it moves decisively toward physical sedation, which is how it tends to end up as a winter evening cultivar. The Linalool/Myrcene pairing leaves a shifting profile that keeps turning up new notes on the palate.
Where it fits: quiet evenings, a film, recovery after exercise, and the hours before sleep.
The Aromatic Three
Leading with Linalool, then Myrcene, and Caryophyllene underneath. This trio turns up repeatedly in cultivars that win things, and it is why a jar of Crystal tends to get a reaction the first time it is opened after curing. Linalool sets the anchor, myrcene fills the middle, and caryophyllene sits in the background doing the work that separates this from every other strain built on the same primary terpene.
Suitability and Recommendations
Crystal is a reasonable fit for anyone, a first outdoor season included. The genetics absorb the usual early mistakes — overwatering, drifting pH, an erratic feeding schedule — without turning a harvest into a write-off. Photoperiod genetics leave size and timing in your hands — hold it in veg for a bigger plant, or flip early when headroom is the constraint. A September-to-May outdoor season comfortably covers a 8-10 weeks bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.
