Make sure to always stay within your state’s legal limit of growing plants.
The first couple months of the year is a great time to start planning your cannabis garden to get a head start on the outdoor growing season, which roughly runs from March to November, depending on where you live.
Cannabis seeds usually come in a pack of 10 or 12 seeds and start at around $40 a pack and go up from there. Some high-end genetics can run between $200 to $500 a pack.

Some strains also take longer to grow than others. Depending on whether you’re growing indoors or outdoors, you may want to grow a quicker marijuana strain if you live in a climate that get cold and wet early in the season. For example, indicas are known for having a shorter flowering time than sativas.
Before you purchase seeds online, you’ll need to figure out what strain you want to grow and what breeder you want to buy from.
If you grow some seeds and like the results, try growing another strain from that same breeder and see how it goes.
Although this option is only available to people living in states with medical and adult-use legalization, buying marijuana seeds at the dispensary is far more straightforward. However, your options are more limited.
Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

How to germinate marijuana seeds
This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.
Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.
At the same time, there are some potential drawbacks to buying seeds from an online store. For one, some weed-legal locations still outlaw buying and shipping seeds across state or national borders. There are also issues of reliability. If you want to buy from an online seed bank , take some time researching the company. Make sure they are reputable and in good standing with their customers.
If you browse through seeds being sold at a dispensary or an online store, you will immediately see some seeds described as feminized or autoflowering. A vital part of understanding how to buy cannabis seeds is understanding the differences in the types of seeds being sold.
Buying seeds online is in many ways the simplest way to purchase cannabis seeds . Buying online makes it convenient to research and learn about the various strains you can grow. Online retailers often have a larger selection to choose from than smaller brick-and-mortar retailers.

Finally, autoflowering seeds have more to do with the growth cycle of the marijuana plant. When growing regular seeds , you will need to adjust the type and amount of light your plant receives in order to trigger the flowering process. But autoflowering seeds have been genetically designed to produce a plant that automatically flowers without you needing to be fully on top of altering the light your plant receives.
You also need to decide if you will be growing your marijuana indoors or outdoors. Growing inside gives you a bit more flexibility as you can control and fine-tune the growing culture for your plants . This gives you more freedom in terms of which seeds you decide to buy. If you plan on growing outside, you should probably spend a bit more time researching the specific seeds you want to purchase to make sure they will thrive in your unique climate and environment.
When you buy regular seeds , some will grow up to produce male plants and others will grow into female plants . You need to be aware of this because growing regular seeds requires you to pay close attention to the sex of each plant so that you can get rid of any males plants that show up. Male marijuana plants do not produce flowers, and therefore will not give you anything to smoke. Even worse, males will pollinate your female plants , producing low quality buds that are full of seeds . If you plant regular seeds , you should plan on buying more seeds than you might actually need, as a higher percentage of these seeds will produce male plants .
