If you allow your seeds to germinate for too long, transplanting them safely will become difficult. The reason for this is that the longer the roots are exposed to air and light, the more likely they are to become damaged. Moreover, the longer the taproot, the higher the risk for accidental damage when transplanting.
Use bottled water for germination. If you need to use tap water, fill a bucket with hot water and let it sit outside for a day. This allows the chlorine to evaporate so the water is safer to use for germinating.
Instead, germinate your seeds directly in soil, or even better, use the Royal Queen Seeds Starter Kit.
9. ALLOWING SEEDS TO GERMINATE FOR TOO LONG
One of the biggest factors inhibiting seeds from sprouting is fungus. Old, reused soil that isn’t sterilised is likely to contain mould and other harmful organisms like bacteria and insects.
Among other critters, ants are particularly keen on eating the taproots from sprouted seeds. To keep your seeds safe, use bird netting, ant traps, and other preventative measures like neem oil or slug traps. Check on your seeds often so you can spot infestations and act before they become a problem.

Keep an eye on your seeds and transplant when the taproot measures 1–2cm at most.
Saving cannabis seeds is a widely used method for preserving genetic varieties that one has particularly enjoyed or that worked very well when planted. Therefore, growers often store some seeds for many years.
But you must be careful: the liquid must not be cold, but rather at a temperature of around 22° C. And you must keep the container away from major sources of light. During the 24 hours that the seeds are there you will have to keep a very close eye on them in order to remove them quickly if they open, so they don´t “drown.”
The key: the storage conditions
If all else fails, there are still a few more aggressive tricks that should only be used when, after a few days, your seeds have failed to hatch and make their way into the world.
Another good investment, which can be key in the case of old seeds, is Jiffy 7. This product is a compressed pill of dried peat that you need to soak for a few minutes. At this point it becomes a small sack of soil that is specially designed to facilitate germination, because it features the ideal structure, is sterilized, has all the necessary elements to nourish the seedlings during the first week, and is pH-neutral. Due to these characteristics it can be your best bet to get your older seeds to sprout.
First, you have won half the battle if you were careful with the original storage. Seeds must be kept in a cool, dry place. Therefore, the best option is to store them in refrigerators at a temperature between 6 and 8 degrees Celsius, and with relative humidity levels between 20% and 30%. And sheltered from light, of course.
Cannabis seeds are real living organisms and as such are susceptible to many environmental factors, such as light, humidity and temperature. If you’re wondering what to do if the seeds don’t germinate, maybe you need to freshen up on what European law says about it.
The first attempt to do among these is undoubtedly to soak the unsprouted cannabis seeds in a container with sparkling water or, better still, enriched with fulvic acid or growing booster. Keep the solution at a temperature of 20°-22° and away from light for 12 hours: in this way you may be able to get moisture into the dehydrated shell and give the embryo the starting input, but be careful not to exceed 24 hours of soaking.
Here’s what to do if your seeds don’t germinate.
Poor germination is not always your fault, as there may be external factors that make it difficult or sometimes impossible. In some cases, the soil used may have been a fungus carrier or its type was not the right one; other times the fault is due to a malfunctioning or poorly calibrated conductivity meter.
Other problems can arise from using chlorine-laden tap water (it is best to let it evaporate 24 hours before use) or from breaking the semen shell due to pressure, which you should always be very careful of.
There are many reasons why marijuana seeds do not germinate, and it is not always easy to recognise the cause. However, there are signs that you may be able to identify those specimens that are likely to cause problems. Improper storage is one of them and can be the cause of your seeds not germinating because they are already dead.
