How to germinate cannabis seeds
Germination is the process in which a new plant begins to grow from a seed. Also referred to as “popping,” germination is the very first step in starting your cannabis garden.
Cannabis seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
When acquiring seeds, you want to make sure they are matured and that they appear dark brown with lighter accents and a hard feel. You don’t want a seed that feels fresh and looks green, which indicates that the seed hasn’t reached full maturity.

What’s the best way to germinate cannabis seeds?
Cannabis seeds require three things to germinate: water, heat, and air. Because of this, there are many methods to germinate your seeds. The most common and simplest method involves the use of paper towels saturated in water.
For this method you will need:
- Two clean plates
- Paper towels
Take four sheets of paper towels and soak them with distilled water. The sheets should be soaked but shouldn’t have excess water running off.
Take two of the paper towels and place them on a plate. Then, place the cannabis seeds at least an inch apart from each other and cover them with the remaining two sheets of water-soaked paper towels.
To create a dark, protected space, take another plate and flip it over to cover the seeds (like a dome).
Make sure the area they’re kept in is warm, somewhere between 70-90°F.
After these steps have been completed, it’s time to wait. You can check the paper towels to make sure they’re still saturated, and if they seem to be losing their moisture, you can apply more water to keep the seeds happy.
Some seeds germinate very rapidly while others can take several days. You know a seed has germinated once the seed splits and a single sprout appears.
This is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination. It’s important to keep this area sterile, so don’t touch the seed or taproot as the seed begins to split.
Transplanting germinated cannabis seeds
Once you see the taproot, it’s time to transfer your germinated seed into its growing medium. Small 2-inch pots are a good place to start.
Fill the pots with loose, airy potting soil and poke a hole in the middle about a quarter-inch down using a pen or pencil.
To transfer the seed, use a pair of tweezers to gently pick it up, then drop the seed in the hole with the taproot facing down. Lightly cover it with soil.
Next, you’ll need to water the soil. Initially, use a spray bottle to provide moisture without over-saturating the soil. You want to give the seed water, but over-watering can suffocate and kill the delicate sprout.
Pay attention to the temperature and the moisture level of the soil to keep the seed happy, and within a week or so you should see a seedling begin to grow from the soil.
Germinating seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
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 and which to breed with other strong plants to create a seed bank of your own.

How is your environment like? Well, in this category of indoor cannabis seeds, you will find an assortment of seeds that can grow in artificial grow environments, those which can get described as semi-permanent, and even grow rooms explicitly meant for cultivating pot indoors. Put simply; nothing should deter you from growing ganja, provided you have the necessary measures in place to control wind, humidity, or light to let your vegetation develop an ultimate growth.
There are plenty of reasons seasoned cannabis farmers may choose to farm cannabis indoors, under a controlled environment. Besides the obvious fact that it allows for effective breeding and cultivation, it separates the crop from contaminants, rogue infestations and undesirable alteration of the specific gene pool.
Indoor farming allows the farmer to maximize time, space and resources to achieve the best yield and maintain strain integrity. But not all seed strains are fit for indoor farming.
At Amsterdam Marijuana Seeds, our grower-oriented approach to cannabis cultivation has been the guiding principle behind the high quality genetics of our seed groups. We apply proven technology to our seed genetics engineering that guarantees a 100% success rate in the production of indoor weeds seeds for sale in the USA, and other countries in the world – that are suitable to grow indoors and in other controlled environments.
Thinking of getting started with indoor weed farming, we have compiled this guide to help you navigate through the process of finding the right indoor weed seeds and getting started on the process of planting cannabis indoors.
Hope you’d find it useful.
What Are Indoor Weed Seeds?
As you should know, before all the magic happened, and the various strains and cross mixes appeared, cannabis was relatively a plant of the wild. The plant grew in whatever climate it deemed fit. Whether it was the ultra cold Ural Mountains or the lush vegetation of equatorial Africa, marijuana survived, but although as various strains that were environment dependent.
But with advancement in farming methods and the domestication of the weed plant, climate dependent weed strains can now be planted in a controlled environment indoors where the same weather conditions in its native environment is replicated, but this time with better control on the elements, nutrients and spacing to achieve an abundant yield and a sturdy plant.
While any type of marijuana seed can be planted indoors, there are some specific strains that would only do so well when cultivated under watchful eyes indoors and in a controlled environment. Photoperiod strains fall under this category.
Photoperiod Marijuana Strains
Basically, marijuana seeds are either photoperiod strains or not. Photoperiod strains are those whose growth pattern is dependent on light cycles. They are very sensitive to light and a distortion in the light cycle can hamper their flowering and production.
A simple distortion in the light cycle of a photoperiod strain during their dip time can result in the loss of the yield. The situation is dire as light pollution such as those from street lights or other sources, even if just for a short time, can potentially cause the plant to revert to its vegetative phase, display hermaphroditic tendencies, produce inferior yields, or fail to flower altogether.
Why Indoor Weed Seeds?
Indoor weed seeds are far from regular seeds . They are more stabilized and are able to produce a higher yield than most if proper taken of. Most indoor seeds are feminized ; as such you do not run the risk of producing male species that are useless to a harvest.
For commercial and recreational growers, indoor seeds offer the best value for money per growth square foot of space.
Whom should buy Indoor Marijuana Seeds?
Indoor seeds are best suited to recreational farmers with only a few pot plants in their homes or commercial farmers with the right financing to afford the rigs required to set up a temperature and lighting controlled greenhouse.
Because of the need for artificial lighting, farming indoor seeds can be a little expensive as you are likely to quickly ramp up electricity bills running into thousands of dollars monthly.
So, before deciding on planting indoor seeds, it is only wise that you consider the ancillary cost associated with the venture to determine if it is right for you.
When to Start Indoor Cannabis Seeds
Growing cannabis is an organic process without strict sets of rules. It is not a linear system to learn, but an art to be mastered. To start indoor seeds, there are three specific needs that must be met – Water, correct temperature (warmth) and a good location.
Each viable seed contains all the information needed to grow the strain of plant you have chosen, all they need are the right conditions and the life cycle will begin. There are a number of equally effective methods for how to grow indoor seeds, over time you will find the one that works best for you.
STRAIGHT INTO THE MEDIUM : Place seeds directly into your medium, this way you can avoid any transplant shock. More often, it is easier to germinate in a small pot of your chosen medium then pot on to the garden or bigger pots.
PAPER TOWEL : Seeds are placed on a moistened paper towel on a plate and placed in a warm dark place. Usually covered with plastic or an upturned plate to retain moisture and humidity. After a few days to a week, your seeds have sprouted.
JIFFIES, PLUGS AND ROCK WOOL STARTERS : Easy to maintain as you can have fifty seeds germinating in a very small space. Once the seedlings are established they can be put in their final position without damaging roots.
IN WATER : Simply soak seeds in enzyme enriched water until you see the tap root appear, and then put in your medium. The seedling will quickly strike and break the surface about a week later.
GERMINATION STATIONS : Offering substantial control over the germinating environment germination stations provide humidity, temperature control and can accelerate germination times.
When your plants have broken the surface and the cotyledons have shed the seed husk and opened to reveal the first set of true leaves photosynthesis has begun. Now you have a true marijuana seedling on its way to becoming a heavy resinous indoor miniature or booming outdoor tree.
Set lights to an eighteen hour day, six hour night light regimen. This doesn’t have to coordinate with the actual daylight hours; you can set it to times of day that suit you. Running electrical equipment during off-peak periods can save you a lot of money. For more information on growing, check out our grow guide .
How to Grow Indoor Seeds
Once your seeds have broken the surface, the vegetative stage has started. Growing seeds indoors would require a couple of fixes and we have outlined them under some headings below:
Lighting (LED, High-Pressure Sodium, MH or CFL): whether you are taking up grow spaces in a disused cupboard in your home or running a full fledged operation in your basement, lighting is the most important factor for growing indoor weed seeds.
There is basically lighting for every budget. You can have a rudimentary yet very efficient CFL (Compact Fluorescent Light) or small LED panel (Light Emitting Diode) setup for just a few hundred dollars. Or if growing commercial, HPS (High-Pressure Sodium) and MH (Metal Halide) lamps would give you world class flowers at the end of the grow cycle
However, watch out for the heat generated by these lamps. Ensure that your space isn’t getting too hot for healthy cannabis growth.
Soil : There are plenty of options in this category. You can choose from actual planting in specifically cultured soil in pot plants or utilize neutral mediums such as rock wool with the roots of the plant immersed in the nutrient infused medium.
Humidity : Large indoor establishments have temperature and humidity controls to manage the grow environment, but if you are on a tight budget, you can apply basic instincts. Always ensure the soil or medium is wet but not soggy. Introduce a fan to circulate air and moisture, and an extractor fan to remove excess heat.
Temperature : Proper temperature is maintained by using fans to remove heat and circulate the breeze. Lots of fan-forced breezes keep temperatures under control and strengthen your young plants. Exotic disciplines can be used like adding carbon dioxide to the environment. Low-stress training and scrogging can be used to increase the growth rate and flower potential of indoor cannabis.
Autoflowering Indoor Seeds or Feminized Indoor Seeds?
You can find indoor seeds in the autoflowering and feminized strains. Although most feminized strains are better suited to indoor grows, autoflowering strains can also produce a good yield with even less hassles when planted indoors.
Some autoflowering strains that would make great indoor grows include:
