It’s a question that marijuana growers have been asking for years: can cannabis seeds go bad? The answer, it turns out, is a little complicated. Let’s take a closer look at what happens to marijuana seeds over time and why they might not germinate correctly.

Marijuana seeds are one of the most important ingredients in growing marijuana. Without healthy seeds, it’s impossible to grow strong, healthy plants. But what happens to marijuana seeds over time? Do they lose their potency or germination ability?


It turns out that marijuana seeds can last for a long time if they’re stored properly. In fact, marijuana seeds can last for years if they’re stored in a cool, dark place. However, marijuana seeds can lose their potency over time. This means that they might not germinate correctly or produce healthy plants.

There are a few things that can cause marijuana seeds to go bad. One of the most common reasons is improper storage. If marijuana seeds are stored in a warm, humid place, they can start to deteriorate. Another common reason for marijuana seeds to go bad is exposure to light. Marijuana seeds need darkness to germinate correctly, so if they’re exposed to light, they might not germinate at all.

Test your Cannabis Seeds

If you’re not sure whether your marijuana seeds are still good, it’s always best to test them before you plant them. There are a few different ways to test marijuana seeds. One popular method is to float the seeds in water. If the seeds sink, they’re probably still good. If they float, they might be bad.

Another popular method is to place the seeds on a damp paper towel. After a few days, check to see if the seeds have sprouted. If they haven’t, they might be bad.
