5 Reasons Your Seeds Just Aren’t Sprouting

5 Reasons Your Seeds Just Aren’t Sprouting

If you have noticed that your seeds just aren't sprouting, there is definitely a reason for this.  In this age of super efficient cloners, it is easy to lose sight of the importance of knowing how to sprout your mother from seed.  Mother plants raised from seed deliver the healthiest clones possible without any degradation to their genetics.  This is important in terms of the quality of product you yield as well as the level of resistance to disease your plants possess.  Let’s take a moment to examine the most common mistakes new growers make while sprouting their plants from seed.



The Top 5 Reasons Seeds Don't Sprout




Seed Quality

The best setup in the world can't make a bad seed sprout.  Learning what qualities to look for in a good seed can help you to determine the sprouting potential.  The older a seed is, the longer it will take to sprout.  Remember seeds are only good for about a year, so try to avoid seeds that are not fresh.  Cannabis seeds need to be stored in a cool, airtight container to stay healthy.  Using fresh seeds can be a great way to increase your odds of success.



It is important that your seed is not buried too deep to make it to the surface and in the case of Cannabis, your seeds shouldn't be buried deeper than a 2" below the surface.    If you bury your seed too deep it will not be able to reach the surface to get the much-needed light required to produce energy through photosynthesis.  You plant may also be restricted in the amount of water it can reach when at certain depths.  In either case, your plant is going to suffer if it cannot reach the surface on its own.  In rooting plugs, you will also need to watch to make sure the hard casing of the shell isn’t lodged in the rooting plug.  When this occurs, it is impossible for your seedling to make it to the surface.


Too Much Moisture

One of the most common mistakes newbie growers make is over watering.  It is true your seed needs a certain amount of water to sprout but if you give it to much water, you are going to drown your seed.  Mold can also start to take hold and suck all the nutrients from your medium before your seedling has access to it.  When this occurs this is known as moisture lock.  Moisture lock not only prevents your seedlings from getting the proper nutrients they need to grow but it also provides a better home for pest and bugs to take refuge in.



You should never sprout your seeds in a garden where pests are present.  Pests such as spider mites can zap much-needed nutrients from your plants and leave them open to other hazards such as molding or fungus.  You should always make a separate sprouting area and if possible, you should sprout your seeds in a chamber to prevent unwanted pests from getting close.  Indoor garden pests are extremely mobile and they will seek out fresh plants to feed on.  If your seedling is attacked, it won't have the strength to survive the onslaught.


Too Much Light

If you are using a high output lighting system such as an MH or HPS, you may have your clones to seedlings too close to your light.  Seedlings are very sensitive to their environment so it is important to keep them in a moderate climate.  If your light is too close to your seedlings you are going to dry out your medium and this will result in your seedling suffering from dehydration.  A LED lighting system is better suited for sprouting seedlings because of its cool operating temperature.
