Guide: Tricks

Germination refers to the stage at which your seeds begin to sprout and grow roots.

Cannabis seeds have been designed by nature to germinate when humidity gets in through the seeds outer shell. For your seeds to germinate and grow correctly, they must be placed in a warm and humid place.A prolonged exposure to water may drown them or make them mouldy.

The germination process is done in two major steps







Planting of the pre-germinated seed


There is much debate among producers on the advantages of pre-germination.

While some hold pre-germination in high esteem, others suggest that you run the risk of making your seed mouldy if they go too far in the germination process before being removed from water.

However, avoiding this problem of over exposure to water is a question of organisation and meticulousness.

The pre-soaking of seeds slightly accelerates the process by ensuring that your seed is completely humid before been planted.

Such proceedings also help you test the seed’s viability before planting – a seed that is suitable for germination will absorb water and become more flexible. This will ease roots shooting out of the seed.


Halfly fill a medium size glass with distilled water. Avoid using tap water, as it most likely contains chloride or some other substance that will affect your seed’s growth.

Most of the time, tap water may be used as well. However, if you do not wish to leave anything to chance in the growing of a high quality plant, you better be meticulous.


Put your seeds in the glass of water.

Avoid putting too many seeds.

The objective of this practice is to have the seeds floating. To this effect, avoid putting too many seeds in the same glass, so that no seed is completely submerged at the beginning of the procedure.


Keep the seeds in a warm and dark place at constant temperature. Germinating seeds do not support light. That notwithstanding, they need some warmth to go through the germination stage.

A seedling heat mat with thermostat or a radiator are good alternatives. The seeds must be put in a dark place: cabinet, chest of drawers, etc. should you choose a heating mat, or a dark room, in case you prefer a radiator.

Cover the glass with another opaque plastic cup, to ensure a dark and proper process. The ideal temperature is about 22 degree Celsius.


Wait until the seeds sink.

Several producers suggest to keep the seeds soaked for a day. The most important is to wait until the seeds sink to the bottom of the glass.

Having the seeds sunk implies that water has got into the outer shell and that the seeds are well humid. Avoid leaving the seeds sunk for long, as this may drown them and increase the risk of rotting.


Carefully remove the seeds from the glass. The seeds are soft and might have grown roots. Therefore, avoid damaging them.

An easy way to remove the seeds from the glass is to gently pour the content of the glass into another glass or a sieve that must have been priorly covered with a paper towel. It will then be easier to collect your seeds.

Planting of the pre-germinated seed


Fill a small container with soil suitable for germination.

Dig a small hole of about 5mm depth.

The standard is to dig a hole whose depth is approximately twice the high of the seed you will put into it.


Carefully put your seed in the hole with the roots facing down.

Fill the hole with soil, without making it compact, in order to ease the seed’s growth.


Use a spray to wet the soil.

Make sure the soil is humid, and not soaked.


Put the containers in a greenhouse covered with a plastic cover. Do not forget to burst some holes on the cover, as this will enable to keep some humidity and will provide an airflow into the greenhouse.

The ideal humidity varies from 70 to 90%, while the warmth temperature remains at 22 degree Celsius. Never allow the soil to get dry throughout the process!


Wait until your plants shoot from the soil and after 4 to 5 days, you will notice that the outer shells of the seeds have begun opening. At this stage, make sure your plants are well ventilated and exposed to light. Remove the plastic cover on the greenhouse.

Put your young plants on a south-facing window, for exposure to sunlight. Better still, place them under neon lights suitable for plant growth. Set the neon lights timer at 18 hours of light. For the remaining 6 hours, the young plants should be left in darkness. At this early stage, the plants are still very fragile. Make sure the environment is warm and the soil humid, but not soaked.


Once your plants have grown firm roots and began developing a second or third floor of leaves, transplant them into a bigger container.

Such stage is generally reached two weeks after planting.

Putting the maximum chances of survival on the side of your seed as from the beginning is a must, if you aspire to a quality harvest. As for any other living thing, what happens at the early stages of growth is vital for the plant’s survival and health.

There are many other germination and planting techniques you may try. These include: planting the seeds directly without any pre-germination, using essences as rock wool, building one’s personal greenhouse, etc. The objective being to find the most convenient planting technique to you.


Finally, no user guide would be complete without cautions.

This is a list of things to avoid when planting cannabis seeds.

Plastic domes or fully-covered greenhouses

Too hot seedling heating mats

Covering the containers with a plastic

Essences that are unsuitable for germination

Fertilised essences

Bad water quality

High EC (electrical conductivity) of the nutrient solution in hydroponics

Cold constant temperatures, ice

Plastic domes or fully-covered greenhouses

Too little or too much water

Cold and dark germination substrate

Spraying the seedlings with organic or chemical pesticides
