Solution: Only plant your seeds in a sterilised (i.e. new) potting mix as this won’t contain these harmful organisms. But your substrate isn’t the only thing you need to keep an eye on. You’ll also need to make sure your containers are clean, as these can also carry mould and other harmful pathogens. If you encounter fungus problems when you’re germinating, it is best to get rid of the seed and the contaminated growing medium and start over.
Your seeds may not sprout at all, or they may emerge from the soil but die days later. Seedlings may suddenly bend and turn brown from a disease known as “damping off”. Overwatering, poor drainage, and lack of aeration will also increase the likelihood of this.
6. TOO MUCH MOISTURE
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.
Likewise, if your seeds are too close to the surface, there is a risk they’ll dry out before sprouting, or the seed will emerge but can’t shed off its cap. The happy medium is to place your seeds about 0.5–1.0cm deep and just lightly cover them with soil.
Likewise, when temperatures are too low, this can introduce a whole host of its own problems, including inhibiting seeds from sprouting. Colder temperatures also increase the risk of other plant diseases. What to do about it? If you want to grow outdoors, don’t set plants outside too early. Instead, germinate indoors and allow your seedlings to grow for a few weeks.
On the other hand, if the weed seeds are too dry, and your germination medium is too dry, the seeds just won’t get enough water to germinate.
Yes, your weed plants will need some fertilizer and nutrients as they grow, but the young sprouts and seeds are extremely delicate.
3. Too Much Light
If you bury the seed too deep, once it does open up, the sunlight won’t be able to reach it, and the sprout will therefore quickly die.
Whatever germination medium you are using, whether water, peat, or paper towel, the temperature needs to be a steady 26 to 28 degrees.
Remember guys, all seeds need to be germinated, not just weed seeds. Of course, in nature, this often happens on its own, but if you want to grow your own marijuana plants, you will to germinate them manually. Seed germination is the act of bringing the seed to life.
Grab a coffee filter and a grip bag as shown below
These are the 10 most common reasons why a cannabis seed does not germinate. Fortunately, the solutions are fairly simple to implement. What are your experiences with non-germinating cannabis seeds?
How is this possible?
5 Hang the bag with a clothes peg or tape (make sure it is between 22 and 27 degrees).
3. wet the coffee filter with spa blue so that the water value is correct, or measure the ph value.
Weedseeds don’t germinate: It’s every grower’s nightmare: if you order some nice seeds, they don’t germinate. Or even worse, you’ve had them in your house for a long time, stored in the best conditions but still nothing happens.
