Residents may grow up to six plants per household, but these must be kept in a locked and inaccessible area. Unlicensed sales remain illegal, and smoking in public spaces is prohibited.
There are numerous dispensaries in San Jose; however, local regulations may vary, so it's advisable to familiarize yourself with the current city ordinances before making a purchase or growing cannabis.

What to Consider When Buying Weed Seeds in San Jose
If you are going to buy pot seeds in San Jose, it's essential to first decide where you intend to cultivate them – indoors or outdoors. For indoor growing, shorter and quick-flowering strains are more suitable, as they can be easily managed in confined spaces. On the other hand, if you plan to grow outdoors, the climate in San Jose allows for experimentation with even long-maturing Sativas and high-yield hybrids. Now let’s take a look at what to consider before searching for cannabis seeds for sale in San Jose.
Climate in San Jose
San Jose is renowned for its warm and dry climate, which allows for almost year-round cannabis cultivation. The summers here are hot, while the winters are mild, making the region an excellent location for growing.
Despite the favorable conditions, it’s essential to keep in mind that cannabis cannot endure prolonged periods of temperatures below 12°C. Thus, seedlings can be started indoors in February and then transplanted outdoors in late March to early April.
From April to November, the plants thrive particularly well. This period provides an opportunity to experiment with exotic strains or to harvest multiple crops of autoflowers. However, if your strain matures at the end of summer, it's crucial to protect it from overheating during the hottest parts of the day by providing shade or additional watering.
Where to Buy Marijuana Seeds in San Jose
While it's easy to find finished products in California, locating weed seeds in San Jose is more challenging. Even in major cities like San Jose, it can be difficult to discover a good variety in local stores.
