Description
Rooted in a lineage that reads like a citrus lover's dream, Orange Velvet Underground RBX Feminised from Ethos Genetics crosses Sour Tangie and Mandarin Sunset before stacking the result against the legendary clone-only Orange Velvet. The nose moves through layers of fruity and earthy depth, with skunky and spicy undertones that keep it from ever reading as one-dimensional. Effects land firmly in very high THC territory, above 25%, with the kind of presence that commands respect from the first session.
On the cultivation side, these feminised photoperiod plants grow large, so growers should plan vertical space accordingly, whether that means low-stress training in a tent or extra canopy management in a greenhouse run. Flowering runs 8 to 10 weeks, a window that suits both dedicated indoor schedules and outdoor finishing in temperate climates. Indoor yields come in at 350 to 450 grams per square meter, with outdoor plants capable of producing 200 to 450 grams each given room to express themselves. For growers ready to manage a vigorous, large-statured plant, this one rewards the effort generously.

FAQ
All you need to know
about this product
Orange Velvet Underground RBX delivers a rare clone-only citrus lineage and 25%+ THC in feminised form, ready for growers who demand something genuinely special.
Orange Velvet Underground RBX is rated moderate to advanced, so it's best suited to intermediate or experienced cultivators who are comfortable managing large, vigorous photoperiod plants. The complex genetics reward growers who understand training techniques and can dedicate close attention throughout the flowering window. First-time growers would find the plant's size and demands a steep introduction.
The lineage stacks three heavily citrus-leaning parents — Sour Tangie brings a sharp tangerine bite, Mandarin Sunset contributes a warmer, sweeter orange depth, and the clone-only Orange Velvet ties it together with earthy, skunky complexity. The result is a multi-layered nose that moves from bright fruit into spicy, dank undertones rather than sitting flat as a simple citrus strain. It's a profile that reflects genuine genetic intention from Ethos, not just a marketing name.
The high is described as both relaxing and uplifting, which reflects the balanced indica-sativa hybrid structure rather than a one-sided sedative or purely cerebral experience. That said, very high THC levels above 25% mean the onset carries real weight, and even experienced consumers should approach with measured sessions. It's the kind of potency that earns its reputation over time rather than on the first encounter.
Indoors, Orange Velvet Underground RBX runs 8 to 10 weeks in flower and delivers an average indoor yield of 350–450 grams per square metre. Per-plant output sits in the 200–450 gram range, which reflects the plant's large structure and the variability that comes with how aggressively you train and manage canopy. Planning for space and vertical growth management will go a long way toward hitting the upper end of that window.
