soaking cannabis seeds

What happens to seeds when you soak them? Why should you soak your seeds? The short answer is because your seeds were designed to be abused. Mother Nature is not kind to a little seed. In the wild, a seed can expect to encounter harsh heat and cold, wet or dry conditions and may even need to survive through the acid-filled digestive tract of animals.

Scarification means to damage the seed coat in some way so that the water is better able to penetrate the seed. Scarification can be done in several ways, including rubbing the seed on fine grain sand paper, nicking the seed coat with a knife and even gently tapping the seed with a hammer to help crack the seed coat.
Take a small bowl and fill it with water from your tap, as hot as your tap will allow. Some seeds can tolerate boiling water, but as the tolerance for heat can vary greatly from species to species, hot tap water is safest for seed soaking.

Once your bowl is filled with hot water, place your seeds inside and allow the seeds to stay in the water as it cools down. Common questions at this point include, “How long should seeds be soaked?” and, “Can you over-soak seeds?”
Lastly, some types of seeds actually contain germination inhibitors that are designed to prevent a seed from germinating inside the fruit. These inhibitors must be leached away before a seed can germinate. In nature, relying on natural rainfall, this process can take some time. Soaking seeds can speed this process up.
In short, seeds have developed over millions of years with defenses to survive awful conditions. But, in your modern day garden, a seed is relatively pampered. Soaking seeds before planting helps you to break down the seed’s natural defenses against what it expects from Mother Nature, which then allows it to germinate faster.
Seed soaking at a basic level needs two things: seeds and water. Some methods for seed soaking may substitute the water for slightly acidic solutions, such as weak tea or coffee or even acidic chemicals. These acidic solutions are meant to imitate loosely the stomach acid of an animal, but these solutions are not necessary in most cases. For most seeds, water will work just fine.

Yes, you can over-soak seeds. Too much soaking in water and a seed will drown. It is recommended that you only soak most seeds for 12 to 24 hours and no more than 48 hours. The seeds of some species of plants can survive longer soakings, but you should only do this if the specific instructions for this species recommend so.

Soaking seeds before planting is an old-time gardener’s trick that many new gardeners are not aware of. When you soak seeds before planting, you can significantly decrease the amount of time it takes for a seed to germinate….

Soaking cannabis seeds

Rockwool is not a natural material – it’s made by heating rock and chalk to 3,000°F and air is blown through the mixture to create thin fibers of rocky material

Jiffy Pellets (Recommended for Soil or Coco Coir)
So how come sometimes it looks like a cannabis plant is growing with its roots pointing up?

You’re trying to give young plants a very small dose of nutrients at first. However, even with young marijuana seedlings, the pH of your water and growing medium is important. Some growers get lucky and happen to have water with the right pH, but if you’re noticing deficiencies and problems with your seedlings, definitely take the time to understand about marijuana root pH and how it affects the plant’s overall health.
Pros of Rockwool
Once your seedlings have developed their first two sets of leaves, then you can move these lights as close as 2 inches away as long as the lights aren’t too hot.
Rapid Rooters Tray
These are round on bottom instead of being a cube, which means they cannot stand up on their own. These are best suited to a hydroponic setup where the Rapid Rooter will be placed directly in the final destination. In our hydroponic setups, we’ve had near 100% germination rates with Rapid Rooters, better than any other seedling cube we’ve tried.

  • Bad for the environment (unnatural material that does not break down)
  • Bad for your health (especially your lungs) – wear gloves and cover your mouth/eyes when handling Rockwool
  • Has a pH that is too high for cannabis, so it must be thoroughly rinsed and treated
  • Poor cloning and germination rates
  • Difficult for new growers
