Pack prices exclude delivery and tax, and bonus seeds are not counted in the per-seed price. Some retailers open their product page on the smallest pack, so pick the pack shown here before comparing. Opening this page does not recheck a price.
Delivery to the United States
What it costs to get them home
Taken from each retailer’s own delivery policy, checked 15 Oct. Pack prices exclude delivery and tax; the retailer’s checkout is final.
Price history, not guesswork
Is now a good time to buy?
The recorded price of one exact pack at one retailer, in the retailer’s own currency. No mixing of pack sizes, shops or exchange rates.

One pack · original retailer currency
Trend averages use the last recorded price per UTC day and need at least 80% daily coverage across the period. Missing days are never invented.
One breeder, one type
Only Advanced Seeds Feminized listings appear here, so a reused strain name from another breeder never sneaks in.
Price per seed
A bigger pack can cost more at checkout and still be the better buy. Every pack is reduced to the same unit.
Dated evidence
Every price shows when we last saw it. Older prices stay visible and labelled, and never lead the page.
