Everyone who has tried to grow marijuana understands how difficult it can be to get the seeds to germinate. There are many moving parts, and a miscalculation in any one of them might spell the difference between a successful growing season and a barren one. You need every advantage you can get when trying to get your seeds to sprout. Some people’s faith in the float test is so strong because of this reason.
Should my marijuana seeds float?
There is common knowledge that marijuana seeds float. To be sure, there are others who hold the opinion that marijuana seeds will drown if submerged in liquid. There is no definitive answer to this topic because it is contingent on factors such as the quality of the water and the strain of marijuana seed being used.
Are seeds viable if they float?
Are marijuana seeds viable if submerged in water? In a nutshell, it’s all about the type of marijuana you’re using.
Not all marijuana strains have the same buoyancy properties; some tend to sink while others float. On the other hand, most types of marijuana may survive if they are submerged in water.
How do you tell if a seed is good or bad?
When floating in water, marijuana seeds sometimes resemble little white stones. The seed will immediately drop to the bottom if it is rotting or has fungus developing on it. Marijuana seeds that are in good health will float on the water’s surface for a while before sinking.
Why do some seeds float on water?
Do you know why some seeds float and others sink when put in water? The embryo and the seed coat are key components in understanding the solution. The buoyancy of the seed is due to the embryo.
About 65% of a seed’s total mass is contained within the embryo, which is a layer of cells. This cell layer has air sacs that prevent the embryo from drowning and allow it to float.
Furthermore, oil globules are located in this layer of cells, contributing to the seed’s signature greasiness. The embryo is protected by the seed coat, which is composed of strong layers that also serve to absorb water. In addition to air and oil bubbles, these strata also have globules.
The oil globules in the surrounding layer are buoyed upward by the force created when water enters these pockets, allowing the seed to float.

How long do you leave seeds in water?
Should you soak your seeds before planting them? is a common question among those interested in producing marijuana. There’s a common misconception that if you just drop seeds into water, they’ll grow. There is no hard-and-fast rule for how long the seeds should soak in water before being removed.
Seeds should be soaked for at least 12 hours before being rinsed and planted, as recommended by many gardeners. Several elements, including temperature, humidity, and light, will determine how long the seeds should be soaked in water.
What happens when seeds are soaked in water?
After being submerged in water, seeds will begin to sink. That’s because the seeds will sink as the water fills the gaps between them. The seeds will enlarge when exposed to water, making them even heavier and sinking them further.
Can seeds germinate in water only?
There are many who think it’s a bad idea to submerge marijuana seeds in water in case they sink to the bottom. Is this theory valid or not?
Yes and no are equally accurate answers. Others of the seeds will float, and some will sink, but it doesn’t matter which ones do, because they will all eventually sprout marijuana plants. A more important factor is whether or not the seed has mould or fungus and how long it was immersed in water. Mold and cell death can develop from seed contact with water if pollutants are present.

It’s commonly accepted wisdom that marijuana seeds that float in water are healthy. However, this assertion is not backed by any scientific data. Some people think that seeds that sink have a better chance of survival; however, there is no evidence to support this.
Remember that low-quality seeds can float just as easily as good ones, thus this test is not 100% accurate. It’s best to wait 12–24 hours before planting seeds after soaking them in water. They’ll have plenty of time to germinate and develop into robust plants.
