WHAT IS THE BEST DEAL WITH OLD CANNABIS SEEDS?

With the cost of seeds above potheads’ reach, old seeds can only fetch us a lot of money. However, improper or long-term storage of seeds may cause seeds not to germinate. But how do we make those old seeds grow back? This guide will show you how! 

 

Taking old cannabis seeds and sorting them

We must distinguish good seeds from those that are bad. When harvesting autoflowering cannabis seeds, everything is preserved and nothing is lost, so there are both mature and immature seeds. How can we tell good seeds from bad ones? Here are some of the things we should consider.

 

Color Sorting And Shape Sorting Seeds

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.

 

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.

 

The classification of seeds based on hardness

Although the seeds have taken some time inside storage containers, ripe weeds seeds’ hardness is not compromised. Hard and tough seeds with a smooth shell guarantee a reasonable degree of germination. Also, pay attention to wavy and cracked seeds. They will lose time and energy and will not germinate after planting. 

 

Old Cannabis Seeds Germinate in 3 Ways

Below we will go through 3 popular methods used to germinate old feminized weed 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.

 

Method 1 – Scarification

The first method is scarification. This includes causing injury to the seeds’ outer shell to allow water and air to enter, which is essential for germination. For manual scarification, we will need a container or box lined with sandpaper or any coarse material to scar the seeds’ outer surface. Put the seeds in a container or box and shake. After a while, we will find that the roots become dull, and we can see parts of the sources inside the container. Once we scare the outer shell of the cannabis seeds, we can germinate them as usual.

 

Method 2 – Carbonated water

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.

 

Method 3 – Mixture of hydrogen peroxide

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. 

 

To use a mixture of hydrogen peroxide for the germination process, use 1 to 2 drops of 99% hydrogen peroxide in a glass of water. After soaking for 24 hours, the outer shell is softened enough to germinate the seeds. 

 

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.

 

  • One part 3% hydrogen peroxide with six parts water.
  •  
  • One part 4.5% hydrogen peroxide with nine parts water.
  •  
  • One part 6% hydrogen peroxide with 12 parts water.
  •  
  • One part 30% hydrogen peroxide with 60 parts water.

 

Keep your water clean and fresh.

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.

 

As a conclusion

Old cannabis seeds sometimes pose a challenge for germination. You can sort ripe seeds, release the hard protective layer by various methods, try new chemical germination enhancers, or use biocatalysts. Similarly, soaking the clean, soft seeds in clean water will push the embryo out of its protective blanket. After trying some of the above processes to germinate the old cannabis seeds, we can be sure to grow healthy and living plants and expect good yields.
