marijuana seed germination time

Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.

For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.

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.

Can I grow a seed I found in a bag of weed?

As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.

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

Most experienced or commercial growers will not use feminized seeds because they only contain one set of genes, and these should never be used for breeding purposes. However, a lot of beginning growers start with feminized seeds because they eliminate the worry of having to deal with male plants.

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.

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.

Another way of germinating cannabis seeds is by using wet paper towels. The best type of paper towel to use is the cheap kind. It may seem strange, but the cheaper ones tend to be non-porous. Non-porous is preferable since the newly sprouted roots will not grow into or get stuck to the paper towel. So, you can save a bit of money.

The paper towel can dry out, so put a bowl or another plate on top to trap the moisture. Alternatively, you can spray the towel every five hours to keep it wet. The process can last one to four days, so check periodically to see if the taproot appeared. If you have older seeds in the paper towel, you may end up waiting longer. Afterward, you can place the young seedling into a growing medium.

Wet Paper Towels (recommended)

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.

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.

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.

However, the Rockwool method also has some drawbacks. The material does not break down since it is not a natural substance. As a result, the cubes are not an eco-friendly option. Rockwool has poor germination rates, and it comes with a high pH level. The material also can affect your health. The Environmental Protection Agency found that the fibers in Rockwool can irritate the skin, eyes, nose, and throat. You may experience a sore throat or coughing.

After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.

If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.
