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 2026-03-05 on 150 seeds.

Germination rate: 96.6% (n=150)
Last QC test date: 2026-03-05
Indoor yield: 478-656 g/m² (avg across 6 verified grower reports)
Outdoor yield: 564-778 g/plant (avg across 5 verified grower reports)

About Grape Gas Feminised

The way to plan Grape Gas is backwards from the day you intend to cut, with Up to 700 g/m² per square metre indoors and Up to 1800 g per plant per plant outdoors as the figures you are working toward, at 28% THC. Count 63-70 days back from that date and you have your flip date. Weight comes on evenly across 63-70 days, with a late surge that punishes impatience. The 60/40 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 Grape Gas — the Up to 700 g/m² indoors and Up to 1800 g per plant outdoors quoted above — is decided in three short stretches of the 63-70 days 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 63-70 days. Stands Medium. Indoors it returns Up to 700 g/m². Outdoors, Up to 1800 g per plant a plant.

Aroma, Flavour and Effect

The first thing Grape Gas does at 28% THC is settle a warm peppery spice at the back of the throat. 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. Limonene sits underneath all of it, adding a brightness that offsets any heaviness.

The Aromatic Three

Leading with Caryophyllene, then Limonene, and Myrcene underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, caryophyllene leads. After three or four weeks in sealed glass at 16-18°C the myrcene 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 myrcene molecules are the first thing you lose.

Suitability and Recommendations

Who does well with Grape Gas? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. It is rated easy, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions. Sent nationwide in plain, unbranded packaging, with sourced grow data on every strain page.
