Cannabis seeds is done and the plants reached a height of 10 to 20 cm, the first critical phase is passed.
No matter if you want to grow your Cannabis indoor or outdoor, the germination should always be done indoor under controlled conditions. If the seeds are very dry or old, it is best to throw them into a glass of water, depending on the age of the seeds, it will take 12-24 hours until the seed hull breaches and a small Cannabis seedling is born. But you should keep checking the glass with water very frequently, as the seedlings will drain if they stay in the water too long. So keep an eye on every seed if the hull is breached, if so take it out immediately. If you decided for the method with the water glass, just fill an average drinking glass with lukewarm water and throw in the Cannabis Seeds. Perfect would be a wide glass, as it makes it easier to get out the small and sensitive Cannabis seedlings. A personal try with this technique shown that a whisky glass did very well, it is not very deep but quite wide and through its slightly thicker glass it also keeps the temperature of the water a bit longer.
Another very popular way to germinate Cannabis seeds is a technique with wet papers and plates. Simply take a plate und put a soaked wet paper on it, no spread the cannabis seeds above it, cover them with another wet paper and place another plate topside down onto it. So it builds a nice germination chamber for your seeds. If you use fresh Cannabis Seeds with high quality, the germination rate with the water glass method is similar. But this technique has a clear advantage over the glass method, when the seed hull breaches, you don´t have to be so fast, as the seedlings won´t drain in the water. Additional it is much easier to get the seedlings from the plate into a flowering pot, than fishing it out of the glass.
No matter which method you choose, place the seeds for germination in a spot with temperatures between 21 °C and 24 °C. Avoid direct sunlight; a dark room or room with dim daylight is perfect. There is no need of special light during day or night; just the right temperature in a dim room will do nicely.
When grabbing the small Cannabis seedlings with your fingers you always risk to squish and kill them.
Also when you got them on the plate you can comfortably wait until the seedling reached a size of 5 to 10 mm, this is the best state to plant the seedling into the soil.
To properly work with the Cannabis seedlings, use forceps to grab them and place them into the soil. It is the best to add small cotton pillows on the end of the forceps, thus ensuring your seedlings are picked up softly.
Now that you know how to germinate the Cannabis seeds and how to handle the new seedlings directly after the seed hull breached, it is time to focus on what to do with the seedlings. Prepare small flowering pots with soil, the size of the flowering pots can be around 8 to 10 cm diameter and around 5 to 8 cm deep. Just use average soil you use for regular flowers to fill the pots, just water the soil and it pushes together without pressing on top of it. After the soil had been watered, it is tight enough for your small Cannabis seedlings, don´t push any further with hands or similar. Your seedlings need to dig their small roots through it, so don´t make it a hard one for them.
Use your small finger to make a hole in the middle of each flowering pot; the hole just should be around 8 to 10 mm deep. Now take the ready seedlings carefully with your forceps and place it into the hole, ensure that the small green stem is facing to the ceiling and not downwards or sidewards. Now use the foreceps and put soil around the seedling very carefully, don´t push it, the base with the rest of the seed hull just should be covered.
Keep the flowering pots with the tiny Cannabis seedlings in the same dim room at 21 to 24 °C. The small Cannabis plants will start growing quickly, so you only have to keep them in the room for 5 to 10 days. Just until they are a few cm in size, perfect is 5 to 10 cm.
Your Cannabis seedlings are now ready to move into their home for growing, no matter if you want to grow cannabis indoor or outdoor. When you place the small plants outside, ensure that they are not in full sunlight at the beginning, cause if temperatures are high, the small plant might dry out, because it is not able to suck up enough water from the soil quick enough. If you are at the beginning of the year or in colder climate, you can also already move them into their final position. Since vermin can easier attack Cannabis plants in the open, start using neem oil from the beginning. It is regular available as solution, that is than thinned with water and sprayed all over the plants. Neem oil is not hazardous like many chemicals and you can smoke your yields without any problems. The Cannabis plants should be sprayed every few weeks when outdoors and can be stopped when flowering begins, since neem oil could alter the taste of your buds if there are leftovers of it in the flowers.
Now you know that it's not that difficult to learn how to grow cannabis!
