About Romulan
Derived from White Rhino and North American Indica, this potent hybrid leans 90% toward its indica roots. The version from Next Generation Seeds produces a piney aroma with sweet and spicy undertones, driven by a terpene profile of myrcene and caryophyllene. It typically tests at 20% THC with 1% CBD, offering a relaxed and sleepy experience that often leads to feelings of euphoria. Growers can expect plants of medium height that flower in 8 to 9 weeks, yielding up to 500 g/m² indoors or 550 grams per plant in an outdoor setting. Because of its sedating qualities, it is frequently used by those dealing with insomnia or chronic pain. The cultivation process is moderately challenging, but the resulting harvest provides a potent, uplifting effect that eventually settles into a calm, sleepy finish.
