how long does it take marijuana seeds to germinate

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

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.

Was the seed found in good weed?

If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.

The paper towel method also has its risk, as the fragile seedlings can be damaged during the potting process. The tiny roots can also get tangled in the paper towels, so make sure to move the seeds to potting soil before roots grow too long. Use your hands or tweezers to gently remove each seed from the paper towels and place them in a prepared growing medium.

The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.

Whether you’re planning an indoor cultivation or outdoor grow, it’s best to germinate your seeds indoors. It’s easier to maintain proper temperature, light exposure, and moisture inside, and you can protect your seeds from the elements. Indoor germination, whether using soil or paper towels, will ensure your cannabis seeds have the best chance for survival.

The paper towel method is also a common way cultivators pop their seeds. Some even use this method with cotton pads instead of paper towels, but the necessary steps are the same.

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.

Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.

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.

There is more than one way to germinate weed seeds. Each one comes with its benefits and disadvantages for growers. Common methods are:

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.

How Long Does It Take for Cannabis Seeds to Germinate

Some general tips for germinating cannabis seeds include:

If it has been well over a week without any signs of a sprout, it is likely a dud. Germinating cannabis seeds requires patience. Keep in mind that the method you use can influence how long it takes.

Next, place the cubes into the bowl and let them soak for one hour. After an hour, take the Rockwool out. They can maintain the correct water-to-air ratio, so it is important not to squeeze the cubes. Like regular starter cubes, Rockwool usually comes with holes already in them. If not, make one that is a quarter-inch deep. Carefully insert a seed and push them to the bottom. Cover the top of the hole and wait. The seedlings finish germination in an average of three days.
