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.
The first step in any farming process is to make sure we have the right seeds, and the same goes for weeds. When harvesting autoflowering marijuana seeds, everything is preserved, and nothing is lost. This means that all types of seeds are ripe and immature. How do we distinguish good seeds from bad ones? You are considering the following.
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.
Method 2 – Carbonated water
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.
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.
Sorting Old Cannabis 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.
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.
You should take sand paper and scuff the seed’s outer shells. Place the piece of sand paper down, then shake the cannabis seeds over it. They will develop some micro abrasions, which in turn will allow them to let in more water.
Getting started with the germination of old seeds may be frustrating for many people. There is a hard shell covering the seed that will not allow water to permeate at first, so it can seem as though nothing is going to happen with the seeds. However, they will swell and break open to begin the process of growing. If you take your time and follow these top 5 tips for germinating old seeds, you are sure to experience great success.
Acid Mixed with Water Is Key
Sand Paper Helps
If you decide to go the paper towel route, wet 2 of them and place the seeds in between. Spray some water on them daily for 3 or 4 days. At this time, they should be starting to sprout.
Take about 33 oz. of water, and use it to dilute about one teaspoon of Fulvic acid. This is the mixture that you will place your seeds in.
A light enzyme or seed booster can be beneficial when dealing with seeds that need some extra help with germinating. It accelerates the germ cycle of the seed for a greater rate of success by restoring the germination capacity of the seeds. Some seed boosters even protect against fungi and bacteria.
