About Big Smooth Feminised

Growing Big Smooth in Ireland is a question of rain and wind rather than of heat or latitude. The whole island runs temperate oceanic, so nowhere is meaningfully warmer than anywhere else — what changes as you move west is how many wet days land on the plant while it is in flower. Outdoors that makes bud structure and the 55 to 66 days of bloom the two things worth reading before anything else, because a dense cola and a wet October are a poor combination. Under a tunnel or under lights the argument disappears: Big Smooth is then judged on its genetics and on nothing else.

Growing it on this island

The pressures here are consistent and they are nearly all about water. Botrytis in dense flower from September onwards is the first, and it is answered with open structure, moving air and a roof — not with anything sprayed on afterwards. Indoors, spider mite and thrips arrive the way they always do, and humidity above 60% in late bloom is what turns a manageable problem into a lost room. Outdoors in a wet spring the slugs do more damage to seedlings than every insect on the plot, and they do it in a single night.

A polytunnel changes the arithmetic on Big Smooth more than any other single purchase. It adds a fortnight at both ends of the season, keeps the rain off the flower during the weeks that matter, and turns a marginal outdoor crop into a reliable one.

Flavour, aroma and effect

Big Smooth arrives in order. The first draw at 26% THC gives peppercorn heat that lands at the back of the throat. The relaxed, happy, euphoric character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Limonene underneath contributes a lift that stops it going heavy.

Terpene breakdown

Primary: Caryophyllene · Secondary: Limonene · Tertiary: Myrcene. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps limonene and myrcene audible over the caryophyllene; run it hotter, or burn it, and all three collapse into one note that is pleasant enough and tells you nothing.

Who it suits

Who does well with Big Smooth? Indoor growers who want to choose their own timeline. Tunnel growers who want to decide when flowering starts rather than letting August decide it. Anyone with the space to veg it properly first. Rated moderate, which means a moderate learning curve that rewards attention without needing specialist kit.

Breeding Programme
Royal King Genetics Backcross Line — BX2 modern hybrid stabilisation
Stabilisation Notes — What This Means for Your Grow

Big Smooth carries clone-derived parents from the mid-2010s. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and trichome production run uniform across the population.

Breeding Goal

Pin the trichome production that came out of the original Big Smooth cross.

Selection Focus

Chosen for vigour, terpene saturation and a tight finish window that allows production planning.

Pollen / Mother Source

Royal King Genetics in-house mother stock — pollen taken from a sibling male drawn from the same selected pheno population.
