what is the best way to germinate seeds

Within a few days some or all of the seeds should open and put out a root. It is common for cannabis seeds to open within 72 hours of being put in the germination medium. Less commonly, some seeds may need up to 10 days or even two weeks to open and put out a root.

Warning!
Unfortunately, regulation and implementation in respect of cannabis seeds often differ from country to country. For this reason we advise you as a matter of urgency to make inquiries about the regulations to which you are subject. Read the complete disclaimer here.

Seedlings intended for outdoors should be acclimatised to direct sunlight by placing them on a windowsill inside the house and increasing their exposure to direct sunlight by an hour or two per day.

Step 2. Germination – How to germinate cannabis seeds

Make a hole in the growing medium that is about twice as deep as the seed is long, so that each germinated cannabis seed sits 2-5mm below the surface.

Place the plates somewhere warm (21ºC) and away from direct light.

Lastly, cover everything with the second plate, upside down, to form a ‘clam-shell’ shape – this will create the dark, moist environment necessary for germination.

When the first few millimetres of root have emerged from a germinated seed, each one should then be carefully transferred to a small container of growing medium (soil, coco-fibre or rockwool).

If you’re a gardening enthusiast, you know there’s nothing more thrilling than seeing the first tiny green shoots come up after you’ve planted seeds. To germinate seeds you will need to give them the correct type of soil and make sure they get the right amount of sun or shade, plus regulate the temperature so they don’t get too hot or cold. Read on to learn how to give seeds the right environment to germinate and grow.

Scarification– This refers to the process of literally damaging the seed coat. Some seeds are so well protected by their seed coat that the seedling is not able to break through it on its own. Sandpaper, knives, or other methods can be used to nick the seed coat to allow a place where the seedling can break through the seed coat.

Cold treatment– Some seeds need to be exposed to a certain period of cold in order to break their dormancy. The temperature and length of cold needed to complete the cold treatment will vary depending on the seed variety.

Dormancy– Some seeds need to have a certain amount of rest time before they can be germinated. A seed’s period of dormancy sometimes also coincides with a stratification process.

Stratification– Oftentimes when someone refers to stratification, they are referring to the process of cold treating a seed in order to break its dormancy, but on a broader level, stratification can also refer to any process used to help a seed germinate. Forms of stratification can include exposure to acid (artificially or within the stomach of an animal), scratching the seed coat or cold treatment.

Pre-soaking– Like scarification, pre-soaking helps to soften the seed coat of the plant, which both speeds up germination and increases the viability of the seeds planted. Many seeds, even if it is not stated in their steps of seed germination, will benefit from pre-soaking.

Many inexperienced gardeners think that the steps for how to germinate seeds are the same for all seeds. This is not the case. Knowing what is the best way to germinate seeds depends on what you are trying to grow and how to successfully germinate seeds varies greatly. In this article you will not find the steps of seed germination for the seeds you have. What you will find is an explanation for different terminology that might be used when you find the directions for seed germination that specifically applies to your seeds.

Viability– When talking about seed germination, viability will refer to the chance that the seed will be able to germinate. Some seeds can sit for years and still have a high viability. Other seeds, though, may lose viability within hours of being removed from the fruit.
