What a cannabis seed bank is
A cannabis seed bank is a seller that stocks cannabis seeds and ships orders to buyers. The term covers two groups: breeders who make the seeds, and resellers who hold stock from many breeders. A buyer picks a strain, pays, and gets seeds by mail or pickup. Convenience, meaning payment speed, shipping time, and delivery to a door, now drives repeat business in this market.

What the seller stocks
Two product types sit under one label. Photoperiod seeds flower when light drops below about 12 hours per day. Autoflower seeds flower on a fixed timer, near 8 to 10 weeks from sprout. Sellers also split stock by sex: feminized seeds are bred to produce female plants, and regular seeds produce both sexes at about a 50/50 ratio. Pack sizes run from 1 seed to 100 seeds. Price per seed runs from $2 for common lines to $30 or more for limited releases.

US law and seeds
Cannabis is a Schedule I substance under the Controlled Substances Act. Seeds that grow into plants above 0.3 percent delta-9 THC by dry weight fall under that schedule. The 2018 Farm Bill removed hemp from the schedule, and hemp seed is legal under federal law. State rules differ. Some states allow seed sales at licensed shops, some allow online sales, and some ban seeds. USPS Publication 52 lists marijuana as nonmailable, and Customs and Border Protection can seize seed shipments that cross a border. No federal agency certifies seed banks.
Payment and shipping
Card networks block most cannabis transactions. Seed banks route payment through bank transfers, cash app transfers, crypto, or cash by mail. Shipping takes 3 to 10 days inside one country and 1 to 4 weeks across borders. Orders carry a tracking code. Delivery to a home address, not a store trip, is the core selling point.

How convenience changed the market
Seed banks compete on four numbers: price per seed, days to delivery, share of orders that arrive, and germination rate, which is the share of seeds that sprout. Buyers moved from walk-in shops to web stores, then to sellers with same-week shipping. Convenience did not change the law. It changed which sellers get repeat orders.
