Ethos Genetics Seeds: Feminized Strains, Autos Included

Six strains, six decisions. That's the full Ethos Genetics selection we carry, which makes it a short list to work through instead of a wall of near-identical names. If none of them fit your space, the wider cannabis seeds range is the next stop.

R1, R2, RF3 and RBX2: Part of the Name, Not a Riddle

Ethos Genetics tags releases with letters and numbers after the strain name: Psy-op R1, Grandpa's Stash R2, Banana Jealousy Auto RF3, Lilac Diesel Auto RBX2. Treat those codes the way you treat "Auto", as part of the name on the pack. We don't have the breeder's own definition for each tag, so we're not going to guess at one for you. What we do know is that Grandpa's Stash R2 came from two selected Grandpa's Stash phenos, 5 and 12, crossed and tightened up so the seeds run more alike than a pheno hunt would.

Three Autos That Wrap Up in 10 to 12 Weeks

Lilac Diesel Auto RBX2 crosses Lilac Diesel 22 with Pluto Auto and finishes 10-12 weeks from seed, staying at 70-100cm indoors with 100-200g per plant outdoors and 25% THC. Bubble Gummy Auto (Gummies x Lilac Diesel Auto F4) takes 11-12 weeks, sits at 30% THC, and opens candy-sweet like a handful of gummy bears before the diesel and woody notes hit on the exhale. Cool nights late in flower can push it purple, though that's a bonus, not a promise. Banana Jealousy Auto RF3 crosses Banana Jealousy with Banana Daddy Auto for 28% THC, 450-550g/m² indoors, 150-350g per plant outdoors, and genuine mould resistance if your airflow is average at best.

Photoperiods for a Tight Indoor Rotation

Psy-op R1 is the workhorse: Crescendo x Bubba Kush, short to medium, easy to grow, 7-9 weeks of flowering, 500-600g/m² indoors and up to 1000g per plant outdoors, at 25-30% THC. Its high bract-to-leaf ratio means less time with the scissors. Grandpa's Stash R2 leans on Afghan, Kush and Skunk stock, flowers in 8-8.6 weeks, resists mould and mildew, and goes sweet pine first, then chem, diesel and skunk. 10th Planet R1 crosses Planet of the Grapes R1 with the Pluto Cut of Quattro Kush for 30% THC, medium height and 8-8.5 weeks.

What We'd Grow First, and What We'd Save

For a first Ethos Genetics run we'd take Psy-op R1. Easy, fast, and it fills out without training. Watch out for 10th Planet R1: grow difficulty is moderate, so it wants a grow or two of experience behind you, and the autos here give you less room to fix a mistake since there's no stretching the veg to recover. Chasing raw strength? Bubble Gummy Auto and 10th Planet R1 both land at 30%. If you'd rather compare across breeders before committing, the autoflowering cannabis seeds category has a much longer list of quick finishers.

Store the Spares Cool, Dark and Dry

Germinate between damp kitchen paper or straight into moist soil, keep it warm and out of direct light, and leave the rest of the pack alone. Seeds keep for years in a sealed container at the back of the fridge, and they hate damp and temperature swings more than anything. Buying one pack this season and one next works fine, so there's no need to run all six at once. Our pick for a single tent, single season: Psy-op R1 indoors, Lilac Diesel Auto RBX2 on the balcony.
