What other growers say
Common Questions
Is this legal to buy?
Our seeds are sold as collectibles to U.S. customers. They ship as seed-only in plain packaging with a neutral business name on your bank statement. We do not talk about growing, using, or selling cannabis on the site or in email.
How do the free seeds and Vault Bonus Stack work?
Every seed pack you add to your cart counts toward the Vault Bonus Stack tiers. When your cart hits $120 / $150 / $180 / $210, we add 18 / 30 / 42 / 63 bonus seeds on top of your main packs. Your cart shows which tier you are in and how far you are from the next one, and the bonus seeds are added automatically at checkout. No coupon codes and no fine print.
What happens if my seeds do not germinate?
We have a 100% germination promise. If you have an issue, reach out with your order number and what happened. We troubleshoot with you and replace or credit according to our policy. The short version is: if something is off and you are acting in good faith, we make it right without a fight.
