tips for germinating a difficult cannabis seed

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.

Instead, germinate your seeds directly in soil, or even better, use the Royal Queen Seeds Starter Kit.

5. NOT USING NEW OR STERILISED SOIL AND POTS

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.

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.

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

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.

Scarification, or scuffing the shell, can also help water pass through an older seed’s tough outer shell.

3. REMOVE THE RIDGE

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.

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.

To scarify your seeds, line a matchbox or other small container with sandpaper. Drop the seeds inside, shake vigorously for 30–60 seconds, then remove. You may not notice much of a difference, but the small micro-abrasions are sometimes enough to let water breach the shell and trigger germination.
