One benefit of the soil method is that transferring the seedling to a bigger pot is simple. The cannabis is less likely to become stressed and can adapt to the new environment quickly. A disadvantage would be needing to buy clean soil rather than using some from outside. Pathogens in the dirt can damage the young seedling. Soil density can be an issue with air flow, and growers need to be careful about the seed placement.
Other than drying out over time, one disadvantage of the paper towel method is that there is a chance of hurting the taproot. Be careful when checking on the seeds, and do not move them too much.
The early development stage requires things like warmth and a gentle touch. You can approach germination in multiple ways. A couple of them are better than others. This article will provide you tips and other helpful information on how to germinate weed seeds. Soon, you will have many healthy cannabis plants growing.
Jiffy Peat Pellets, Starter Cubes, and Seedling Plugs
You only have to worry about making sure the seeds are not soaking for too long. The method is more effective when you follow it up with the paper towel method. Damp paper towels can help get any remaining weed seeds to sprout.
Some cannabis growers use Rockwool cubes to germinate weed seeds. The method requires some setup before you can plant the seeds. Start by filling a bowl with some water. Use some pH-balancing chemicals to bring the water down to around 5.5. You may need a test kit to measure the levels.
Place the seed inside the hole and cover it up. Then, you can add some water. The packaging should have instructions on how much water to add. The weed seeds can take anywhere from two to five days to finish germinating.
The water method is effective for hard seeds but is time-sensitive. Not to mention, the steps are simple to do, and results can be quick.

Start by filling pots with a premium-quality soil that has been soaked in water. Many growers also choose to lace the water with a root stimulator. Make a hole roughly 10–15mm deep. This will be your seed’s new home. Remove the seeds from their packet and place them into the pre-dug holes. Loosely cover the seeds, but be careful not to compress the soil above the seed too much. The root will struggle to penetrate solid soil, slowing plant growth. Lightly spray the top of where you placed the seed so that your growing medium stays moist.
If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.
USING STONE WOOL BLOCKS
The soil pots will need small holes (roughly 10–15mm deep) for the newly germinated seeds to be placed into. Once the seeds are secure, you will want to place a fluorescent light 13–15cm (5–6 inches) away to encourage growth. Finally, don’t risk overwatering your seeds at this early stage. Use a plant mister to make sure they stay damp but not soaking wet.
Maintaining the ideal temperature (between 22–25°C/71–77°F) and moisture for germination is tricky. Leaving seeds out in the open environment or on a windowsill is far from ideal; a DIY climate-controlled cupboard would do a much better service. A warming mat is perfect for maintaining a constant temperature, but it doesn’t tackle the issue of moisture.
Planting directly into your growing medium prevents having to move seeds when they are at their most fragile. That first root tip is covered with microscopic filaments that are easily damaged. Given that both a cup full of water and moist paper towels are more prone to temperature fluctuations from their environment, planting in soil is a much safer option.
Before we jump straight into the germination methods, there are a couple of germination golden rules. For the best results, we recommend staying within these guidelines, no matter how you choose to germinate. That being said, of all the factors to consider, temperature is one of the most critical. Seeds will always seek out even the smallest amount of moisture, but they use temperature as a sign that they need to do so.
Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.
Was the seed found in good weed?
Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.
One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.
These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
