Our Germination Guarantee
If fewer than 80% of your seeds germinate within 90 days, when you follow our germination instructions, we replace them. That is the whole promise. This page explains how it works in practice, because what people actually worry about is not the percentage — it is what happens when something goes wrong.
Why 80% and not 90% or 99%
Plenty of seed banks advertise higher numbers. We guarantee 80% because it is a figure we can stand behind on every strain we sell, in every season, including older genetics and small batches. A guarantee you can rely on is worth more than a number that looks good until the day you need it. The same thinking runs through our honesty policy.
How to claim
- Follow our germination instructions. This matters — the guarantee covers seeds that fail despite correct handling.
- Get in touch within 90 days of receiving your order.
- Tell us what happened: how many seeds you planted, how many came up, and the method you used.
- We send replacements. No lab report, no photographs of your grow, no argument.
We replace seeds rather than refunding. There is no refund or store credit.
Shipping problems are covered separately
Seeds that never arrive are a different problem from seeds that do not sprout, so they have their own cover. Our 100% shipping guarantee applies if an order arrives damaged, wrong or incomplete, or never arrives at all: we replace it or send a new order. The details are on our shipping page.
Giving your seeds the best chance
Most germination failures come down to a few avoidable things: seeds left soaking too long, a medium that is too wet, temperatures that are too low, or seedlings handled before they are ready. Follow the instructions that come with your order, keep the medium damp rather than soaked, and leave them alone while they work.
Frequently Asked Questions
What is your germination rate guarantee? 80% within 90 days, when our instructions are followed.
What if my package never arrives? Our 100% shipping guarantee covers it. We replace the order or send a new one.
Do you offer refunds? No. We replace seeds or orders rather than refunding, and we say so up front.
How long do I have to make a claim? 90 days from receiving your order.
What do I need to provide? How many seeds you planted, how many germinated, and the method you used. Nothing more.
Why don’t you advertise a higher germination rate? Because 80% is what we can guarantee across every strain we sell. We would rather promise less and honour it than quote a number we cannot back.
Does the guarantee cover seized packages? Our shipping guarantee covers orders that do not arrive, whatever the reason.
