California has long been the heart of cannabis culture, and today, buying seeds here is completely legal for adults 21 and over. Whether you’re a home grower looking to cultivate your own plants or a collector building a seed library, the Golden State gives you plenty of freedom to get started.
Since Proposition 64 legalized adult-use cannabis, Californians have been able to buy, possess, and grow cannabis at home. The key is knowing the limits and following state guidelines. For many residents, ordering from a trusted online seed bank like Growers Choice Seeds is the easiest way to explore high-quality genetics without leaving home.
Cannabis Laws in California
Is it Legal to Buy Cannabis Seeds in California?
Yes. Cannabis seeds are legal to purchase in California. Adults 21 and older can buy seeds for personal use from licensed dispensaries or online seed banks. Proposition 64 made cannabis legal for both medical and recreational purposes, so there’s no penalty for owning or buying seeds as long as they’re for personal use.
Age and Purchase Restrictions
You must be 21 years of age or older to purchase cannabis seeds for recreational purposes. Medical patients can also buy seeds with a valid medical marijuana card, regardless of age, if authorized by a physician.
Home Growing Regulations
California law allows adults to grow up to six cannabis plants per household for personal use. These plants must be kept in a secure, private space out of public view. While local municipalities may impose additional restrictions, home growing is legal statewide under state law.
Types of Cannabis Seeds Available
Autoflowering vs Feminized vs Regular Seeds
Feminized seeds grow into female plants, which is ideal for maximum yield and no male surprises. Autoflower seeds switch to flower based on time rather than light schedules, which makes them fast and beginner friendly. Regular seeds produce both male and female plants and are used by breeders who want to work with new crosses and keep genetics stable.
Best Cannabis Strains for California’s Climate
California’s Mediterranean climate suits a wide range of cultivars. Coastal zones favor sativa-leaning hybrids that love long sunny days, while inland areas excel with fast-flowering indicas and balanced hybrids. Local favorites include Blue Dream, OG Kush, and Gelato, all proven cultivars in California’s warm, dry summers.
Where to Buy Cannabis Seeds in California
Californians have more options than most states when it comes to buying cannabis seeds. Because both recreational and medical cannabis are legal, you can buy seeds from licensed dispensaries, online seed banks, or directly from trusted U.S. suppliers like Growers Choice Seeds.
Buying Seeds at California Dispensaries
Many dispensaries across the state sell cannabis seeds alongside flower, clones, and other products. Larger dispensaries in cities like Los Angeles, San Francisco, and San Diego often partner with local breeders or carry well-known cultivars such as Blue Dream, OG Kush, and Gelato. When buying in person, you can ask staff for recommendations on strain type, climate compatibility, and ideal grow setups. The benefit of buying from a dispensary is immediate access and the ability to see packaging, labeling, and freshness firsthand.
However, not all dispensaries stock seeds, and when they do, the selection is usually limited. Availability often depends on local supply chains and seasonal demand. Because of this, many growers prefer to shop online where there’s a wider variety and more consistent availability.
Buying Cannabis Seeds Online in California
Ordering seeds online from a reputable seed bank like Growers Choice Seeds gives you access to hundreds of cultivars from across the U.S. and beyond. Online shops typically carry both feminized and autoflower options, along with high-THC, high-yield, and CBD-dominant varieties. Buying online is also more convenient—especially for those who live in rural areas or regions with limited dispensary access.
