10th Planet R1 is an Ethos Genetics first-generation cross from Colorado, part of a catalogue that favours dessert and fruit terpene profiles on potent frames. Like all Ethos R1 drops it is bred for phenotype hunting rather than uniformity, and it suits growers who already know what they are looking for.

Genetics and lineage
10th Planet R1 is a feminised photoperiod variety from Ethos Genetics, classed as indica / sativa hybrid. The breeder lists its parentage as Planet of the Grapes R1 x Quattro Kush (Pluto cut). Potency is rated very high THC (25%+), which places it at the top end of the current catalogue — not a strain for a first grow or a first smoke.
Planning a grow of 10th Planet R1
Indoors, plan on roughly 11–13 weeks from seed to harvest: about 4 weeks of vegetative growth before switching to 12/12, then 7–9 weeks of flowering.
Outdoors in central and northern Europe (Netherlands, Germany, northern France) this flowering length is comfortable: plants started in May are usually ready in late September to early October, ahead of the wet weeks that cause bud rot.
Medium height: fits a standard 1.2 m tent without training, though a single topping evens out the canopy.
What yield to expect
The breeder rates indoor yield as high yield (450-600gr/m2). Outdoors the rating is high yield (450-750gr/plant), which assumes a full season in good sun and a large container or open soil. Treat these as the ceiling under experienced hands; a first grow typically lands at half to two-thirds of the figure.
Aroma and effect
Growers describe the terpene profile as fruity, skunky and spicy.
