Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.
Additionally, every long-time grower will tell you that clones degrade over time.
In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.
How to germinate marijuana seeds
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.
There are a few indicators that will give you a sense of whether the seed is worth germinating.
Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.
To employ water germination, fill a glass with tap water and let it sit until it reaches room temperature or around 65 degrees Fahrenheit. Add two to three plant seeds per cup and allow them to sit, watching for any changes. Change the water to fresh tap water every two days, making sure it stays at room temperature.

Use a spray bottle to moisten the paper towels and then store the cushioned seeds between two plates, under a face-down bowl, or gently place them in a plastic bag. Maintain a temperature of about 72 degrees Fahrenheit, keeping the paper towel wrapped seeds in the dark and away from a windowsill. In two to five days, the seeds will pop inside the paper towel sandwich and emit tiny roots, ready to plant when they reach about five millimeters in length.
The downside of water germination is that once they’ve popped, you’ll need to maneuver them into their growing medium manually. This is a delicate process, as germinating seeds are extra fragile, and any harm risks the development of your plants. Make sure to place the seed roots down in the soil when you transfer to a pot.
Soaking cannabis seeds in water is more advantageous for the ones with a harder shell. Older seeds can benefit from the method as well. The water helps wake them up, in a sense. Another benefit is that it is not as costly. All you need is a clean glass cup and some distilled water.
Each cannabis seed is different. Some plants will finish their germination stage quickly, and others will take some time to sprout. On average, you can expect germination to last two to four days. Some growers end up waiting 48 to 72 hours. In some cases, a seed may take seven days to germinate. You usually do not need to wait longer than 10 days.

A disadvantage of soaking the seeds in a cup is that too much water can be damaging. The excess amount can rot the newly emerged root. Those that have not sprouted yet will drown if left soaking for too long.
Peat pellets, starter cubes, and seedling plugs are easy to use, which is beneficial for beginners. You do not have to worry about spending time for preparation. Another advantage is that you can transport the cubes with ease, especially if you use a tray.
Growers will find that different methods work best for them. When it comes down to it, germinating cannabis seeds in water is the best way to go about it. You can get the taproot to emerge in hard and older seeds. Overall, putting water into a glass is cost-effective compared to buying starter cubes.
