RP 43’ S1
Dank, gassy, indica-dominant S1 strain.
RP43 S1 is an indica-dominant S1 strain. The process for creating S1 strains (or selfing) is to stress a female plant into producing male flowers, harvesting the pollen, and subsequently using this for fertilisation purposes. RP43 S1 is named after legendary NASCAR racing driver Richard Perry.
RP43 S1 grows into a short, stocky plant indoors, reaching a height of approx. 120cm. Outdoor-grown plants can grow considerably taller than this. Indoor flowering time is about 9 weeks with yields up to 500gr/m2. Outdoors, in the northern hemisphere, harvest will be ready in early October.
Terpenes include humulene, caryophyllene, limonene, and myrcene. The aroma is earthy, fruity-citrus, and diesel fuel. Its high THC gives a potent effect that begins in an uplifting manner but which evolves into a much more relaxed, even sleepy, feeling.
Therapeutic uses include treating insomnia and increasing appetite.
