About CBD Sour Lemon Feminised
Read CBD Sour Lemon backwards from the harvest: 350-400 g/m2 under lights, 550-600 g/plant outdoors, with resin filling out towards 8% THC. Weight goes on evenly across the 10-12 weeks of bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 44/56 split gives you calyx density and an even spread of resin rather than one at the cost of the other. Outdoors, late September to mid-October is the window that misses the wettest of the finish across most of the country while still letting the myrcene arrive.
Getting the weight out of this plant
Three stretches of the 10-12 weeks of bloom decide whether you reach the top of this strain's range (350-400 g/m2 indoors, 550-600 g/plant outdoors). The rest is maintenance.
The first ten days of flower. What the plant does during the stretch sets canopy height, and canopy height sets how evenly the light lands. Somewhere around a third is typical. One pass of low-stress training over the tallest shoots keeps the top flat.
Weeks three to five. Myrcene production climbs through here, and it responds to a day-night temperature gap of 6-8°C. British autumn nights hand that to outdoor growers for free from September; indoors you have to build it, at roughly 25-26°C lights-on and 18-20°C lights-off. Bloom feed goes potassium-heavy around EC 1.6-1.8.
The last ten to fourteen days. Stop feeding and run pH-corrected water. Check trichomes daily under a 60x loupe — cut at 10-15% amber for the middle of the range. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.
Flowering: 10-12 weeks. Indoor yield: 350-400 g/m2. Outdoor yield: 550-600 g/plant. Plant height: 1.5 m. Rated intermediate difficulty.
Flavour, aroma and effect
CBD Sour Lemon arrives in stages. The first draw at 8% THC brings a musky earthiness that coats rather than cuts. The focused, calm character follows within minutes, as a head and body effect at once. The mind stays clear while the muscles let go by degrees, which is what makes it adaptable — a small dose carries an afternoon, a larger one turns into an evening. The bisabolol underneath adds a complementary note that fills out the middle.
Terpene breakdown
Primary: Myrcene · Secondary: Bisabolol · Tertiary: Linalool. This combination turns up often in cultivars that win things, and it is usually the one growers comment on when a jar is opened for the first time after curing. Myrcene anchors the aroma, bisabolol occupies the middle, and linalool sits behind both — which is the part that separates this strain from others sharing its primary terpene.
Who it suits
Who does well with CBD Sour Lemon? Indoor growers who want the timeline under their own control. Outdoor growers who want to choose when flowering starts. Anyone with the room and the patience to veg it properly before flipping. Difficulty is rated intermediate, which means a moderate learning curve that rewards attention without demanding a laboratory.
