cannabis seed won t crack

Keep the water warm, but not too hot. Aim for around 22°C. Avoid direct sunlight, and keep an eye on the glass. Do not soak seeds for prolonged periods, more than 24 hours can deprive them of oxygen and make them drown.

To improve your chances, use carbonated water and/or add one of these supplements that help with water absorption. Fulvic acid and most boosters also give your seeds a light dose of nutrients.

2. SCARIFICATION

The older a cannabis seed gets, the harder it is to pop. But hard doesn’t mean impossible. If you’ve been saving your seeds for a rainy day and it finally started pouring, these tips could help you get most, if not all, of your old beans to germinate.

As you proceed through these steps, the risk of damaging your seeds past the point of recovery increases. Between each suggestion, give them a few days to a week to germinate. Allow the outside to dry each time to prevent rot. Do not try all or multiple techniques at once.

Removing the ridge not only makes it easier for the seed to open, it helps with water absorption.

Keep an eye on your seeds and transplant when the taproot measures 1–2cm at most.

Why are my seeds not germinating? With our germination troubleshooting guide, you can get to the bottom of why your weed seeds aren’t popping. Avoid these germination mistakes and get your grow off to a great start!

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.

10. POOR WATER QUALITY

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.

Believe it or not, hemp seeds are a major component of many types of birdseed! That’s right; birds love them just as much as you do. But birds aren’t the only critters that would love nothing more than to chow down on your seeds.

Unless you are using cuttings, growing weed starts with germinating your seeds. If your seeds don’t sprout, for whatever reason, your grow will be over before it even has a chance to start. But If you know the reasons behind germination problems, your chances of getting your grow off to a great start will greatly increase!

I have 20 odd random seeds that weren’t germinating after 2 weeks, figuring they were all just dead I decided to crack one open and have a look see whats going on. Sure enough it seemed healthy inside so I put it back in and sure enough 2 days later she sprouted.

After having a read of a 2011 thread I figured might as well try the next 10 seeds and so far so good. They all seem to still be alive so I’m going to crack 10, leave the other 9 as they are and just see what happens. The below is 2 of the ones I just cracked today.
