marijuana seeds start germinating then stop

Handling your cannabis seeds with bare hands can contaminate them with all kinds of nasties like bacteria and fungus. Unfortunately, seeds and seedlings are especially vulnerable to these types of harmful pathogens.

To get your grow off to a great start, sourcing quality cannabis seeds is the best thing you can do. Not only will your germination rates be better, but your plants will also grow healthier with better yields at harvest time.

3. HANDLING SEEDS WITH BARE HANDS

Got a bag of “mystery seeds” from your local source or “bargain seeds” from an unknown vendor off the internet? If so, chances are they won’t germinate. Reputable seed banks like Royal Queen Seeds will always test their seeds for quality and germination rate.

Seeds don’t need light to germinate. In fact, too much light can decrease their likelihood of popping. You only need to worry about providing light once your seedlings actually emerge from the soil. But make sure to start with low light intensity before gradually increasing over time.

But if the seed you found looks decent, you might as well germinate it and see what sprouts.

Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.

As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).

Is the seed viable?

As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.

You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.
