growing marijuana seeds in water

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.

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.

Do Cannabis Seeds Need a Light or Dark Environment for germination?

Rockwool comes with a few advantages. One is that the cubes are cheap and easy to find. They can hold plenty of moisture, and you do not have to worry about mold. Not to mention, they are convenient to use.

One benefit of the paper towel method is that you can leave sprouted seeds in the towel for a while longer. It allows other seeds to catch up, and you can plant them all at once. Otherwise, you can plant the germinated ones as soon as the taproot appears.

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

However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

Climate considerations

Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:

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.

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.
