Pack sizes and rankings

Choose a seed count and seed type on a strain page. We find the cheapest combination of available packs from each listing that meets or exceeds your count, then rank the totals. A combination can contain more seeds than you requested; the row shows what you would buy.

Catalog prices per seed divide the pack price by its seed count. Those figures exclude shipping and coupon codes. The comparison table adds shipping when enabled and applies a listed coupon where available.

Shipping and coupon codes

Shipping figures are our tracked rates or estimates for a US order, with known free-shipping thresholds applied. Optional delivery upgrades, taxes, and address-specific charges are not included. Confirm the final amount at checkout.

When a rate is unknown, the row says “+ shipping.” We use $11.00for ranking that row instead of assuming delivery is free. Turning shipping off compares pack subtotals only. A displayed coupon must be entered at the retailer's checkout; eligibility can change.

Checks and price history

Collection runs regularly, but a retailer may fail a check or change its price between visits. A strain's “checked” time is its most recent recorded price check; it does not mean every retailer was checked at that moment.

History covers recorded in-stock prices from active listings at banks marked as shipping to the US, within a rolling 30-day window. We show the observation dates and number of observed days. The low is the lowest recorded pack price per seed, before shipping and coupon codes. Missing days are gaps, not zero prices.

The trend compares the first and last observed daily low once there are at least five observed days. Different banks or pack sizes can set those lows, so it is not necessarily a price change on one identical pack.

Genetics and growing details

Strain facts are assembled from our catalog and from breeder and seed-bank listings, including automated extraction and name matching. Descriptions retained from the earlier Leafist catalog do not always have an original source URL. Where that is the case, we say so.

Parentage links show reported relationships. A confidence score is an internal assessment of extraction and matching, not a measured genetic percentage, a calibrated probability, or independent verification. Parent order is not recorded, so an “A × B” display does not establish which parent was maternal.

Reported yields, flowering times, cannabinoid values, aromas, and effects can vary by source and growing conditions. We have not independently tested these claims. Unknown facts are left blank. Records may group listings that use the same strain name; check the breeder and product details before ordering.

Affiliate links and corrections

Some retailer links earn Leafist a commission at no extra cost to you. Advertisements are separate from the price ranking, and commission is not a sorting input.
