germinating marijuana seeds with hydrogen peroxide

When your old cannabis seeds don’t want to pop, one of these four techniques could come to their—and your—rescue. Aging seeds are more difficult to grow than fresh ones and we’ll explain what you can do to help germination.

The older a cannabis seed gets, the harder it is to pop. But hard doesn’t mean impossible. If you’ve been saving your seeds for a rainy day and it finally started pouring, these tips could help you get most, if not all, of your old beans to germinate.

1. PRE-SOAK WITH SUPPLEMENTED WATER

To improve your chances, use carbonated water and/or add one of these supplements that help with water absorption. Fulvic acid and most boosters also give your seeds a light dose of nutrients.

As cannabis seeds age, their protective outer shell hardens and prevents water from passing through. Unless the tiny, dormant embryo that lives inside the shell detects moisture, it doesn’t know that the conditions are right to sprout. As a first step, pre-soak your old cannabis seeds for about 12 hours to see if that does the trick.

Scarification, or scuffing the shell, can also help water pass through an older seed’s tough outer shell.

In addition to chemical and mechanical scarification, we can use other DIY methods to loosen seeds. For example, we can use a small knife to scratch or open the seed coat. We can explore different approaches as long as we do not damage the seed embryo.

Below we will go through 3 popular methods used to germinate old weeds seeds. Remember that we have to do the part by trying to keep the temperature between 26 ° C – 28 ° because that is where the clones seem to season-best. You must also ensure that the seed is kept in a dark area, as light can slow down the germination process.

The second method involves the use of carbonated water with a pH below 7. This slightly acidic solution absorbs the outer layer of the seeds. Put the seeds in a container full of carbonated water and wait for about two hours. The solution loosens the seed coat and allows it to absorb water, which helps germinate.

Always Use Clean, Fresh Water

Whether we obtained the seeds from a seed bank, a store, or a retailer, different cannabis seed strains have different colors. Mature cannabis seeds acquire a dark coat, while immature ones are brighter and usually white. The most visible colors are brown, tan, and sometimes black. In contrast, bright yellows and whites quickly identify immature seeds.

Clean and clean water contains oxygen and hydrogen molecules. These are two life-supporting elements necessary for germination. Soaking the seeds for at least 12 hours allows water to enter living cells, a process known as osmosis. Now that the internal conditions promote germination, the semen embryo expands and breaks out of the protective sheath.

Cannabis seeds are known for their aesthetic properties and shape. Round and symmetrical seeds are best. Larger seeds have a reasonable rate of germination compared to small seeds, which tend to be immature.

Method 3 requires that we use a mixture of hydrogen peroxide to soften the seed’s outer skin. It would be best if we were careful when mixing the peroxide solution, as we can burn the seed, and it will never germinate.
