Pluto Cut RF3 Auto takes one of the most decorated Kush cuts around and packs it into an easygoing autoflower. Ethos Genetics built her from the Pluto Cut of Quattro Kush, a multiple-cup-winning clone, crossed with its own OG Kush Auto F4, then worked the line forward to a reversed third generation. The result is a squat, heavy-flowering auto with classic indica weight and a seed-to-harvest window of roughly 80 to 90 days.
Her aroma is pure old-school Kush with a twist: incense and sweet flowers drift over a sharp gasoline base. Ethos Genetics rates her at TAC up to 25-30%+ and points to her alternative cannabinoids as the reason her effects feel so intense. If you know the Pluto Cut strain by reputation, this is a way to grow that character on a fast, light-independent schedule.
Beginner friendly, high yielding and comfortable indoors or outdoors, Pluto Cut RF3 Auto is one of the most approachable Ethos seeds for growers who want serious Kush flower without a long photoperiod run.
Lineage and the RF3 Generation
The Pluto Cut is a celebrated selection of Quattro Kush that has collected multiple cups. Ethos Genetics paired it with OG Kush Auto F4, an autoflowering OG line the breeder had already carried through four filial generations. That OG Kush Auto parent supplies the autoflowering trait and a dense Kush structure, while the Pluto Cut contributes its terpene depth and unusual cannabinoid profile.
RF3 means reversed F3. In practice, Ethos selected the top females in the early generations and used reversed females to make the next round, so every seed is feminized and the line is three generations deep. Each generation of selection tightens the expression, and by the third the plants carry the autoflowering habit and the Pluto Cut flavor far more reliably than a first-generation cross would.
It is a good example of what Ethos cannabis genetics do so well: taking an elite clone-only plant and translating its character into a stable seed line that home growers can actually pop.
Aroma, Flavor and Effect
The bouquet opens with temple incense and sandalwood, warm and resinous, before a layer of sweet flowers softens it. Underneath it all runs a cutting gasoline note with a sour, chemical edge. On the palate the smoke is thick and earthy-sweet, with pine and fuel lingering long after the exhale.
Ethos describes her effect as classic indica and adds that she packs a heavy punch. The breeder also lists a euphoric effect among her benefits, so expect a warm, happy head change that gradually spreads into a deep, heavy body feel. This is an evening strain: put on a movie, settle into the couch and let her do the work.
Growing Pluto Cut RF3 Auto Indoors and Outdoors
Like every autoflower, she starts blooming on her own as she ages. There is no need to switch the lights to 12/12; most growers keep an 18/6 or 20/4 schedule from germination to harvest. Ethos says that depending on the environment, flowers are often well developed before day 80, while the full life cycle runs about 80 to 90 days.
Her frame is short with medium to short internodes, and she builds big flowers that pack out every bud site. That makes her ideal for small tents, closets and low-ceiling rooms. Light LST in the first three weeks keeps the canopy flat so that every bud site gets direct light.
One useful note from the breeder: she will keep growing for 100+ days if left alone, but her appearance can start to decline past her prime. Watch the trichomes and harvest on time instead of waiting for more bulk.
Outdoors and in greenhouses she thrives in full sun and a loose, well-aerated soil. Her compact size keeps her discreet in the garden, and her short cycle allows more than one run in a long season.
