Know what you are growing
One breeder, one type
Only Barney's Farm 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.
