Cannabis Seeds in California

Recently, California has emerged as one of the best places in the world to purchase weed seeds and grow them. In this post, we’ll tell you how to take this to the next level by buying the best cannabis seeds in California. We’ll also briefly touch on legal issues and climate conditions. Read on.
Is it Legal to Buy Cannabis Seeds in California?
Under California state law, adults 21 and older may legally purchase, possess, and use cannabis seeds with the explicit purpose of growing them for personal medical or recreational use.
The 2018 Farm Bill legalized hemp at the federal level, defining it as Cannabis sativa L. and any part of that plant, including seeds, as long as the THC content does not exceed 0.3% delta-9 THC on a dry-weight basis. Because of this definition, hemp seeds are federally legal.
However, marijuana remains illegal under U.S. federal law, where “marijuana” is still defined to include viable cannabis seeds, unless they qualify as hemp or are sterilized and incapable of germination. In practice, cannabis seeds are widely sold online and shipped to California, but there’s a chance that federal customs may intercept the package, so it’s vital to choose a seed bank that offers discreet shipping options.

Can You Grow Cannabis in California?
In accordance with Proposition 64, passed in 2016, adults aged 21 and over may grow up to six living cannabis plants per household for personal use.
Local governments retain the right to regulate cultivation. Counties and municipalities may, for example, ban outdoor cultivation entirely, restrict visibility, require plants to be grown in a locked and enclosed area, or impose additional rules. Indoor cultivation inside a private residence cannot be fully prohibited, but it can still be regulated. Always check local ordinances before planting.
If you’re a medical patient, meaning you have a recommendation from your physician, you can plant as many medical marijuana seeds in California as necessary to ensure a constant supply of the medicine (as stipulated by Proposition 215).
Best Cannabis Strains to Grow in California
If you’re wondering what the best strains to grow in California are, the short answer is: all of them! Whether you prefer Indicas, Sativas, or their hybrids, you can have them all, and your choice is limitless. In our list below, we’re focusing more on the Sativa-leaning genetics because not every climate allows their cultivation, and Californians shouldn’t waste their advantage.

What to Consider When Buying Weed Seeds in California
When looking for cannabis seeds for sale in California, your only consideration will be whether you want to grow indoors or outdoors. For indoor cultivation, you probably want to choose smaller and faster cultivars, while outdoor growing doesn’t limit you in any way.
Climate in California
The fact that the state is home to the famous Emerald Triangle and that pot seeds in California are among the best in the world speaks volumes about how accommodating the local climate is for cannabis cultivation. Unless you live too high in the mountains, any CA zip code gives you an opportunity to grow weed practically all year round.
Just bear in mind that cannabis can tolerate very short forays into below-freezing territory but isn’t crazy about them. In general, weed stops growing with temps below 54°F and waits for warmer days. This means that you can start your cannabis indoors in February and plant it outside when it’s big and robust.
Between April and November, the weather is perfect, and this allows you to grow even exotic Sativa strains with an extremely long flowering time or have multiple consecutive harvests of autoflowers. And one more thing – for strains that mature in August or September, make sure they get some shade in the afternoon, as flowering plants don’t benefit from extreme heat.
