Cannabis seeds in California

Sunny California is a place to rub shoulders with the rich and famous, hit the beach, or grow some sweet weed. That’s right; cannabis seeds in California are legal.You read that correctly; in this sunkissed state, it’s legal to grow marijuana. There are several places where you can find marijuana seeds for sale in California.It might sound like a dream come true for cannabis connoisseurs, but it can be a challenge cultivating crops in this hot climate. Read on to find out just how you should go about getting the best out of your marijuana seeds in California.

Is it legal to buy and grow cannabis seeds in California?

Is weed legal in California? Since 2016 it’s legal to purchase, grow, and use weed on the gold coast. You can freely buy cannabis seeds in California and cultivate the plants for personal use.

Even though the law is pretty lax when it comes to buyomg cannabis seeds in California and growing pot, some rules still need to be adhered to.

  • Being over 21 years of age to use marijuana.
  • You can’t have more than six cannabis plants at a time.
  • You can only grow the plants where you live, and they must be out of sight and locked up.
  • If you’re on the move, you can only carry 1 oz of weed.
  • There are restrictions for growing marijuana outside, but none on indoor growing.

If, for whatever reason, you land up in trouble related to marijuana charges, don’t stress. In California, you’ll quickly find a cannabis lawyer to help you out.

Should you grow weed indoors or outdoors in California?

California is known for its sunny days and mild evenings. It makes it a perfect place for cultivating cannabis. You would be forgiven for thinking that you could grow marijuana there all year round, but unfortunately, the state has some chilly winters.

Keep in mind that temperatures can drop to a mild 40°F (4.4°C) to 50°F (10°C), so it’s too cold to cultivate cannabis crops outdoors.

We take a look at the benefits of both outdoor and indoor weed growing in California.

Climate conditions

In northern California, farmers have a long season. Cannabis seeds can be planted outside early and harvested later in the season due to the region’s warmer weather.

Many growers use the spring equinox to indicate that it’s time to get the outdoor growing process started.

Make sure that your plants are in the ground by the summer solstice rolls around to get the best yield out of your marijuana seeds in California.

When the weather starts to turn, you’ll notice that your cannabis plants are plump with sticky buds. Don’t be tempted to harvest just yet, and instead wait for the fall equinox to cut the crops.

The aim is to have everything cleaned, dried, and cured well before winter sets. You’ll find that the dispensaries in California are quiet during the colder months since the weather isn’t suitable for outside cultivation during winter.

If you want to keep your weed seeds growing all year long, consider an indoor grow room.

When it comes to indoor cultivating, once you buy cannabis seeds in California , you can plant them in pots or grow containers any time of the year. It takes between 3-7 days to germinate pot seeds .

Many growers prefer cultivating weed crops indoors since the seedlings are delicate.

A home-based grow room allows you to control the temperature and humidity using automated controls.

California marijuana gardeners can start growing the bushes outside when the weather is warm and then bring them inside when it gets too cold.

This is only viable if the cannabis plants are potted in mobile containers. Another option is to install a greenhouse to take advantage of the golden state’s sunny climate in the summer months and continue to cultivate in the chilly winter weather.

Best strains to grow in California

If you’re not sure which strains are ideal for growing in La La Land, then visit one of the many California dispensaries or check out the online cannabis seed banks.

There’s bound to be a weed enthusiast that’s more than happy to share his knowledge with you. We’ve picked two strains that we know will be a hit in your garden.

From the feminized seeds section, we’ve picked the California Dream strain . True to its name, this indica/sativa blend enjoys a warm sunny climate. It does well outside and in a greenhouse set up.

Known for its pain-relieving benefits, it’ll have you feeling uplifted, focused, and happy after harvesting.

Indoor Cannabis Seeds in California

If you’re searching for cannabis seeds in California for indoor setups, look no further than the Critical Purple Auto strain . The Indica dominant weed plant is excellent for beginner growers, and its bright purple foliage looks amazing in grow rooms.

It’s not a herb you should indulge in during the daytime, but for relaxing and de-stressing at the end of a long day, it’s the queen of high THC seeds . Do your research early, and don’t be afraid to compare the different California dispensaries’ prices .

Shopping around will guarantee that you get the highest quality marijuana seeds for your money.

Where to buy cannabis seeds in California

It’s difficult to tell how many dispensaries in California a person can find. Since it is legal to buy cannabis seeds in California , many places sell weed seeds , some of which aren’t specialist stores.

The range of marijuana for sale in physical stores might not be substantial enough to cater to all tastes.

You might find that an online cannabis seed bank will carry a particular type of weed seed that you can’t find anywhere else.

Purchasing California cannabis seeds online allows you to try various strains and shop around for different prices quickly.

Specialist sites such as i49 genetics give you a vast range to choose from and give you in-depth information on cultivating the seeds. We suggest you start your PC and get online to get your research going.
