Doppler is a feminized, photoperiod-dependent hybrid created as an S1 self-cross of Mendo Breath, resulting in a stable and homogeneous expression of the cultivar’s dominant traits.Plants develop a compact, bushy structure with minimal stretch, producing dense, resin-heavy buds that display purple hues in both foliage and flowers alongside thick orange pistils.The aroma intensifies throughout flowering, combining sweet and earthy tones with subtle skunky notes. Indoors, Doppler stays below 80 cm, benefits from apical pruning to promote lateral branching, and requires humidity control below 60–65 percent due to the density of its colas; recommended practices include lollipopping lower growth before flowering. Indoor yields range from 400–450 g/m². Outdoors, the cultivar performs well but requires caution in rainy or humid climates, while its Mendo Breath lineage provides resilience against pests and environmental stressors; outdoor production can reach 800 g per plant. The flowering period is 50–55 days.THC levels range from 22–26 percent, producing a swift, strong body-centered effect characterized by deep relaxation and suitability for evening use, while some uplifting sensations may appear early in the experience. Medical users may find applications for pain relief, appetite stimulation, and general relaxation.As an S1, Doppler expresses reduced vigor compared to non-selfed hybrids but compensates with uniformity and consistent phenotypic traits.
