Last Modified: May 18, 2019

It’s finally time for you to become the ultimate cannabis connoisseur. After years spent consuming and enjoying marijuana grown by others, in 2019, you’re ready to buy cannabis seeds and start growing your own. Online seed sellers are ideal due to the selection, convenience, and privacy they provide. But where do you begin? What kind of seeds should you buy? How do you find a reputable online seed shop?

There are a lot of factors for you to consider before you buy cannabis seeds online. The location and growing conditions you’ll be working with, as well as the desired effect of the final product will determine which strains will be best for you to grow. You’ll also need to think about the current laws where you live, as well as your need for privacy when it comes to placing a transaction and having the product shipped to you.

This guide will help take you through the process of narrowing down your seed strain, as well as choosing an online seller from which to buy cannabis seeds online.

This guide is currently being rewritten – the full version will be up in few days.

What Kind of Growing Space Do You Have?

One of the biggest considerations in figuring out what type of cannabis seeds to purchase is where you’ll be growing your plants. Because different strains are incredibly diverse in terms of their growing needs, there’s sure to be one that will suit your space. This is part of the reason that it’s helpful to buy cannabis seeds online, as online seed sellers provide such an amazing selection.

Indoor or Outdoor

While you can grow cannabis both indoors and outdoors, the latter is an unusual option in most places due to illegality, theft, and damage concerns. People typically opt to grow indoors to ensure privacy and the safety of their plants. If your 2019 grow space will be indoors, you’ll want to buy cannabis seeds that will do well under artificial lights, as natural sunlight will be in short supply.

For those who are fortunate enough to have a safe and secure outdoor grow space, most strains will do well if they receive enough sunlight and water. You’ll still need to take your climate into consideration, however. Here’s an overview of the concerns you may have, depending on your area.

Mediterranean Areas

The hot summers and mild winters of the Mediterranean provide an ideal climate in which most strains can thrive and flourish.

Continental Areas

Many strains will do well in the hot summers of this type of climate as long as the humidity stays low. High humidity will create moldy plants and unsmokeable weed.

Cool Areas

If you plan to grow outdoors in a cooler climate, you’ll need to choose a quick-flowering strain and grow during the summer when temperatures are the warmest.

Hot Areas

If the summer temperatures in your area tend to skyrocket, proper irrigation is a necessity. As long as the humidity is low, your plants will remain mold-free—a huge relief.

As you can see, growing outdoors introduces a variety of factors to the process that are out of your control, so it’s key to start with the proper seeds. If you’re growing indoors, you can better control the amount of light and water your plants receive. You can also do things like installing a dehumidifier and an exhaust system to control humidity levels.


If you can’t have an outdoor garden, plant size becomes a concern. If you’ll be growing indoors, make sure you research your seed strains to ensure that you don’t produce Godzilla-sized plants that will crowd out and take over your entire available space.


Since cannabis plants can smell quite strong, this can be problematic if you’re growing indoors in a connected, multi-family dwelling such as an apartment or a townhouse that shares a wall with your neighbors. To avoid complaints, make sure you install proper ventilation or buy cannabis seeds that will produce low-odor plants.

Growing Time and Gardening Expertise

Two other items to consider: How long you are willing (or able) to wait for your plants to mature and flower?  Also, do plants tend to thrive or die while in your care? Here’s an overview of the different types of seeds and what you need to know.

Regular Seeds

If you have a bit of a green thumb and would like to spend 2019 perfecting your cannabis breeding technique in order to become a marijuana master, you’ll need to work with regular seeds. A regular seed can produce either a male or a female plant. Male plants won’t produce any buds, but they will produce pollen that combines with female plants to create more seeds.

While you won’t be able to tell whether a seed will produce a male or a female plant, you can assume that roughly half of your seeds will produce females. Most growers simply grow a few extra plants to make up for the males they end up with. Regular seeds are less expensive than autoflowering seeds.

Feminized Seeds

Feminized seeds eliminate the cannabis gender guessing game. Each of these seeds has been bred to grow into a female plant and will do so 99.9% of the time. For those who are new to the world of buying cannabis seeds, unlike male plants, female plants create the beautiful, sticky buds that harvesters want.

Autoflowering Seeds

Feminized seeds make it easy to know that you’re growing bud-filled, female plants.  For those who aren’t gardening enthusiasts and simply want to grow some bud, autoflowering seeds make things even easier.

While other seeds require the grower to toy around with the lighting in order to stimulate the flowering process, auto flower seeds don’t need such care. They flower automatically (thus their name) and much faster than regular seeds. In fact, some can flower in as little as 35 days.

Do You Have a Green Thumb?

When you buy cannabis seeds for your 2019 crops, think about your level of gardening expertise. If you’re a newbie to growing anything, feminized seeds will let you cut right to the chase and grow gorgeous buds without having to discard unwanted male plants. Autoflowering plants are obviously a bit more maintenance-free than regular ones. Beyond that, research different strains to find out what will be involved in obtaining an optimal, high-quality yield.

Speaking of Strains

Which strains you choose will depend on your growing conditions and gardening expertise, as well as the type of effects you hope to get from the harvested product. Each strain comes with different combinations of cannabinoids, which are the active ingredients in marijuana. Cannabinoids such as THC, CBD, and others plug into the cannabinoid receptors throughout our bodies, simulating natural body chemicals. This makes cannabinoids helpful in easing symptoms and treating various illnesses.


If you think of THC as the psychoactive cannabinoid, you’ll have a better idea of what to expect if you buy cannabis seeds that will produce high-THC strains. The cannabinoid found in highest concentrations in most strains, THC makes you feel extremely happy and relaxed.

In larger amounts, it can create interesting auditory and visual effects. For example, music may sound more intense while the listener is under the influence of THC, or they might see visual “trails” flowing out behind moving objects. THC can impair motor skills, perception of time, short-term memory, and concentration.

Medicinally, THC works well as an appetite stimulant. It also helps reduce nausea and vomiting, making it an all-around good treatment for people with cancer who are undergoing chemotherapy.


As you begin to research the various strains of cannabis seeds, you’ll note that besides THC, many strains also feature a certain level of CBD. This cannabinoid is non-psychoactive and can actually reduce the psychoactive effects of THC when the two are taken together.

If people feel any effects from CBD, they may experience a subtle relaxation. This is part of why CBD is helpful in treating anxiety. Its mood-lifting effects make it useful as a treatment for depression. CBD has also been shown to be a wonderful treatment for conditions such as fibromyalgia, multiple sclerosis, and epilepsy.

Particularly if you’re interested in growing cannabis for medical purposes, researching and educating yourself about different strains is important. While there’s an almost infinite number of strains to choose from when you buy cannabis seeds online, let’s discuss the two general classifications of strains: indica and sativa.

Relax with Indica

Cannabis indica is a short, squat plant. It typically grows less than 5 feet tall and has dense, bushy leaves. The branches grow close together and the leaves are wide. Indica usually takes around 6 to 8 weeks to fully mature and be ready for harvest. Indica flowers can smell quite pungent and skunky, so keep that in mind if odor is a concern in your grow area.

Once harvested, ingesting indica will give you a relaxed, “body” high. People enjoy indica for its calming effects. Take care with strong indicas or large amounts, though, as too much can create “couch lock” that can make it tough to move around and take part in normal activities. Indica works particularly well as a sleep aid. It’s also useful as a pain reliever, a muscle relaxer, and an anxiety reducer.

Get Energized with Sativa

Other strains you’ll find when you buy cannabis seeds online will be categorized as sativas. These plants grow taller than indicas—usually around 6 feet high, but sativa can grow as tall as 20 feet tall if you grow them outdoors. The branches on these plants grow rather loosely and the leaves are long and narrow. Sativa takes anywhere from 9 to 12 weeks of grow time before it’s ready to harvest, and the flowers can smell sweet, floral, and somewhat fruity.

Unlike indica’s relaxing “body” high, sativa provides a cannabis boost that’s frequently described as more of a psychoactive “head” high. People enjoy it for the energy, motivation, and creativity it gives them. People often use sativa strains as an appetite stimulant, to control their ADHD, or to treat depression.

The great thing about buying cannabis seeds online is that it gives you a wonderful opportunity to research the perfect strains, read reviews, and find an incredible selection that features exactly what you want.

The Purchasing Process: Where to Buy Cannabis Seeds in 2019

Now that you know the basics of choosing seeds, the next step is to find a good online store. Here are a few tips to help guide you and make your buying experience a positive one.

What Are the Laws Where You Live?

Marijuana laws differ from country to country and in some places, from state to state. If you’re planning to grow in a place where possessing, using, and growing cannabis is fully legal, buying seeds is no problem. If possessing and growing weed isn’t legal in your area, purchasing seeds gets more tricky. While possessing small amounts of marijuana typically isn’t a major criminal offense in places where it’s illegal, growing marijuana is often punished more harshly.

Only you can decide what level of risk is acceptable for you to take. Of course, we don’t encourage anyone to knowingly break the law. We do wish to educate those who seek more information, however, believing that the more people become educated about cannabis, the faster the laws that prohibit it will change. We’ve seen a virtual cannabis revolution in the years leading up to 2019 and hope to see the forward motion continue.

Do Your Research

There’s nothing more frustrating than wasting money on seeds that are duds, aren’t what you ordered, or never arrive. In order to avoid most seed-buying snafus, it pays to do your homework ahead of time. When looking into seed sellers, look for reviews. Find out if they have a good reputation amongst previous customers. Another thing to look into is whether marijuana is legal in their location. If so, wonderful. If not, this is an indication that you’re purchasing from a shady operation.

Privacy is also a huge concern, especially if you live in an area where weed is not yet legal. Browse through the seller’s website and see if they take precautions to protect your privacy. For instance, conscientious seed sellers will refrain from storing your personal information.

Will They Ship to Your Country?

Although this may seem like an obvious thing, make sure they will ship to your country. It can be disappointing to wander through a site and get psyched up about the seeds you’d like to buy…only to find out that they won’t ship them to you. Shipping restrictions arise when a company starts having a high rate of unsuccessful seed shipments to a given area. Sometimes the restrictions are temporary while the company changes shipping strategies, and sometimes a company will break off shipping to a particular country altogether in favor of focusing on areas where the successful shipment rate is much higher.

If a company does ship to your area, make sure you read the terms. In many cases, you will have to assume the responsibility if the package doesn’t get delivered. In other words, if you live in a country where marijuana is illegal and your seeds are confiscated by customs, you’ll be out the cost of the order. It’s a bit of a gamble, but it’s one that can pay off due to creative stealth shipping methods.

Stealth Shipping

Getting your seeds confiscated by customs is a real bummer and a blow to your wallet. It’s especially frustrating, for instance, for people who live in states like Colorado where cannabis is legal, but where overseas shipments must still go through U.S. customs and abide by federal laws that criminalize cannabis possession, growing, and consumption.

For those who are nervous that their seeds might get caught up in customs or discovered by a family member or roommate who checks the mail, high-quality seed stores typically offer stealth shipping options. Stealth packaging ideas are endless. Your seeds might be sent tucked inside a DVD case (that includes a real DVD), or they could arrive cleverly disguised as a package of candy or folded inside a rolled-up T-shirt. Because many seed companies don’t use their name in the shipping information on the packaging, these shipments are very easy for authorities to overlook.

Because there are still so many places where buying and using marijuana is illegal, you’ll find that a lot of seed sellers have become experts at stealth shipping. It’s almost just as much fun to see how creative they get in disguising your seeds as it is to actually get them.

Secure Payments

We talked about privacy and protection of your information earlier. Another factor that’s important if you want to buy cannabis seeds online is the ability to make a secure payment. When I say this, you’re probably thinking along the lines of SSL encryption that allows credit card and other information to be transmitted securely so that hackers can’t obtain it.

When it comes to buying marijuana seeds, though, there’s another level of security to consider. Even if the information is transmitted securely, a credit card transaction leaves a record that can be traced to the purchaser. If privacy is a big concern for you, look for a cannabis seed seller who accepts Bitcoins as payment.

Using Bitcoin to Grow Bud

In 2019, Bitcoin is an increasingly popular way to anonymously buy cannabis seeds online. It’s a digital form of currency that’s not tied to any central bank. It allows users to make instant payments online without having their identity or personal information connected to the transaction.

If privacy is a big concern for you, find a seed seller that takes Bitcoin as payment. If you’re growing in an area where weed is legal, you’ll be able to use a credit card to buy cannabis seeds online, as well.

Do They Have a Good Seed Selection?

After you’ve determined which shops will ship to your country, as well as which ones use privacy precautions that make you feel comfortable, it’s finally time to narrow your choices down to the shop with the biggest seed selection. We suggest narrowing your choices down in this order because it won’t do any good to find that tasty strain you’ve been dreaming of for sale at a shop that won’t ship to your country.

The Difference Between Seed Banks and Seed Shops

With such a huge selection of places to buy cannabis seeds online in 2019, it will be helpful for you to understand the difference between a seed bank and a seed shop. A seed bank actually breeds different strains and sells the seeds. A seed shop simply sells seeds (say that three times fast!). You’ll find that seed banks have a better selection and often feature unique and hard-to-find strains.


Whether you wish to grow weed for recreational or medical purposes, starting this endeavor isn’t as easy as simply choosing a random strain from any shop and making a purchase. Before you buy cannabis seeds online, it’s important to know which kinds will best suit your grow space, climate, and needs. You also need to be well-educated on the cannabis laws in your area, especially as laws have continually changed in the years leading up to 2019.

Choosing the best seed seller is important, as well. Of course, you want to find one with a good selection and high-quality products, but you also want to ensure that you buy cannabis seeds from a shop that takes your privacy into consideration and does everything within their power to make your shipment as discreet as possible.

Since growing and harvesting any plant takes a certain amount of know-how, we hope you’ll read additional tutorials to fully educate yourself on the specific strains and growing methods that are appropriate for your grow space. We hope we gave you a good understanding of where to start in your search for seeds and sellers. Happy growing!
