Frequently Asked Questions
Quick answers about buying cannabis seeds in the UK, delivery, seed types, and our service at Rhino Seeds.
What are autoflowering seeds?
Autos flower by age rather than light cycle, finishing fast and staying compact — ideal for quick, low‑maintenance runs.
How long do autos take?
Most finish in 9–11 weeks from seed. Some fast lines are ~8–9 weeks depending on phenotype and environment.
Are autoflowers potent?
Yes. Modern autos rival photoperiods for potency and flavour — strains like Gorilla Cookies Auto and Lemon Cherry Cookies Auto hit hard.
