Quality seeds are the key to healthy plants and good harvests. While proper feeding/watering and good light quality obviously also affect the health and yield potential of your plants, starting a grow with top-shelf genetics is equally, if not more important. But how exactly do you tell quality cannabis seeds apart from the rest? In this article, we’ll show you exactly how to spot top-quality cannabis seeds, avoid duds, and start your grow off right.
Immature cannabis seeds, on the other hand, tend to be green and have a soft outer shell that breaks when any kind of pressure is applied to it.
Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds
This simple and cost-effective method is a great way to tell the good genetics from the bad; they will sink or swim, literally. Seeds that remain buoyant on the surface are more than likely of poor quality and are to be discarded. Seeds that sink to the bottom like a botanical cannonball are probably healthy and should be germinated.
The fact that cannabis seeds can vary in appearance has led some growers to think that the size, shape, or color of a seed dictates its quality.
With this said, you may get lucky if the strain they were growing really is prime. In this case, it’s worth carrying out the following test to see if it’s worth germinating.
Sowing dud cannabis seeds can prove to be a waste of time and effort. But how can you tell the healthy ones apart? Take a look at these tips for some guidance.
Below are a few simple and easy methods you can use to assess the quality of your cannabis seeds.
SOURCE OFTEN DETERMINES QUALITY
One cost-effective and simple trick to determine if your seeds are worth the time is to see if they float in water. Fill up a glass or jug with water and place your seeds on the surface. Leave your seeds in the water for a few hours and return to check on them later. Seeds that have sunk to the bottom of the water are healthy and should be germinated now that they have been soaked. Any seeds that remain floating on the surface are likely of bad quality and shouldn’t be used if you don’t want to risk wasting time.
There’s another box that needs to be ticked off the list before growing as well, one that is often overlooked. Checking the quality of your cannabis seeds before placing them in the soil is a simple process, and one that can save a lot of time and energy in the long-run.
Healthy seeds are mostly hard to the touch and should be able to resist external pressure when placed between the index finger and thumb and given a squeeze. If your seed cracks under this pressure, then it’s a sign of a weak and unhealthy one.
However, the Rockwool method also has some drawbacks. The material does not break down since it is not a natural substance. As a result, the cubes are not an eco-friendly option. Rockwool has poor germination rates, and it comes with a high pH level. The material also can affect your health. The Environmental Protection Agency found that the fibers in Rockwool can irritate the skin, eyes, nose, and throat. You may experience a sore throat or coughing.
The seedling plugs and cubes already come moist. However, the setback is they dry out over time. Once you open a package, you have over a week to use them. Many products do not provide less than 50 cubes. If you plan to germinate only a few seeds, you could end up wasting a lot of cubes. Therefore, this method can be less cost-effective than others.
Soaking cannabis seeds in water is more advantageous for the ones with a harder shell. Older seeds can benefit from the method as well. The water helps wake them up, in a sense. Another benefit is that it is not as costly. All you need is a clean glass cup and some distilled water.
Best way to germinate cannabis seeds
While cannabis seeds primarily need to remain moist, you can soak them in water overnight. All you need is a glass cup. Fill it with three-quarters of a cup of water that is filtered or pH neutral. Make sure the temperature is neither cold nor warm. The ideal temperature is lukewarm.
The water method is effective for hard seeds but is time-sensitive. Not to mention, the steps are simple to do, and results can be quick.
The life of a cannabis plant begins in the germination stage. It finally starts to sprout after a period of being dormant. Even a seed that is a few years old can become a thriving plant. Growers need to provide special care when trying to germinate weed seeds – like they do with any growing plant.
A disadvantage of soaking the seeds in a cup is that too much water can be damaging. The excess amount can rot the newly emerged root. Those that have not sprouted yet will drown if left soaking for too long.
