About CLTVRS
CLTVRS is short for cultivars, plant varieties that growers have selected and refined over generations. Finding, keeping and sharing great cultivars is what we're about.
The seed bank
Since 2021, CLTVRS has been a small, grower-run seed bank. We focus on regular seeds from small-batch breeders we know and trust, including Mountain Fire Genetics, Exotic Alchemy, Raw Genetics, Future Genetix, Holy Anointed Genetics, Osiris Genetics and Keys To The Kingdom, alongside classics from established houses.
Why regulars? Because males matter. Regular seeds let you hunt every phenotype, make your own crosses and keep a line going for years. That's how great cultivars are made in the first place.
- Breeder freebies with orders while they last
- Discreet packaging and fast shipping within the U.S.
- We never sell or share your information
The strain database
We also run a free, open encyclopedia of more than 9,000 cannabis strains: lineage, breeders, lab-tested THC and terpene results from state registries, effects and flavors, and reviews and photos from real growers. Every description is written by us from the facts, and the data is refreshed weekly. See where our data comes from.
