Royal King Genetics — Seed-Lot Testing
Figures below come from our own seed-lot testing rather than breeder marketing, taken from a single batch tested 2026-02-19 on 400 seeds.
About Do-Si-Dos Auto
The way to plan Do-Si-Dos is backwards from the day you intend to cut, with 550-650 g/m2 per square metre indoors and 280-350 g/plant per plant outdoors as the figures you are working toward, at 22% THC. Count 70-75 days seed to harvest back from that date and you have your flip date. Weight comes on evenly across 70-75 days seed to harvest, with a late surge that punishes impatience. The 50/40 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot — after the summer humidity has broken, before the first Highveld frost.
Where the Weight Actually Comes From
Yield on Do-Si-Dos — the 550-650 g/m2 indoors and 280-350 g/plant outdoors quoted above — is decided in three short stretches of the 70-75 days seed to harvest bloom rather than evenly across it.
The first ten days after the flip. Whatever stretch happens here sets your canopy, and an uneven canopy wastes light for the remainder of the grow. Stretch of 30-40% is normal. One round of low-stress training on the tallest shoots levels it out.
Weeks three to five. This is when caryophyllene production climbs, and it answers to the gap between day and night temperature rather than to either number on its own. Keep at least 6-8°C between them. Outdoor growers in the interior provinces get that swing free in March and April; indoors, aim for 25-26°C lights-on against 18-20°C lights-off, with potassium-led bloom feed at EC 1.6-1.8.
The last ten to fourteen days. Stop feeding, flush with pH-corrected water, and read trichomes daily under a 60x loupe. Cut at 10-15% amber to keep both sides of the hybrid in play. Outdoors that usually lands between late March and mid-April.
Difficulty: easy. In flower for 70-75 days seed to harvest. Stands 80-110 cm. Indoors it returns 550-650 g/m2. Outdoors, 280-350 g/plant a plant.
Aroma, Flavour and Effect
The first thing Do-Si-Dos does at 22% THC is settle a warm peppery spice at the back of the throat. The euphoric, happy, relaxed 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. Limonene sits underneath all of it, adding a brightness that offsets any heaviness.
The Aromatic Three
Leading with Caryophyllene, then Limonene, and Myrcene underneath. This trio turns up repeatedly in cultivars that win things, and it is why a jar of Do-Si-Dos tends to get a reaction the first time it is opened after curing. Caryophyllene sets the anchor, limonene fills the middle, and myrcene sits in the background doing the work that separates this from every other strain built on the same primary terpene.
Suitability and Recommendations
Who does well with Do-Si-Dos? 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.
