The amount of water you supply your seeds during the germination process will also affect their ability to successfully germinate. Some growers attempt to germinate by “drowning” them in a glass of water. While this ensures they will not go thirsty, it can actually be more harmful than helpful.
Once they pop, seedlings are very delicate and must be watered carefully. When germinating, your medium should be damp, but not overly wet for best results. On the other hand, a dry environment is basically a death sentence for your seeds. They need a constant source of moisture to sprout, otherwise they’re good as duds.
Germinating cannabis seeds is necessary in order to sprout seedlings that develop into mature, healthy cannabis plants. However, complications with light, humidity, heat, and more could result in cannabis seeds failing to sprout. Find out what to avoid to ensure successful germination.
TOO MUCH OR NOT ENOUGH WATER
Cannabis seeds require a specific temperature range in order to germinate. Regardless of the germination medium you are using (soil, paper towels, etc.), the temperature in the environment should consistently sit in the 26–28℃ range. Seeds need to be kept warm during the germination process. At no point during germination should seeds be exposed to temperatures below 20℃.
Seeds that have been improperly stored may also fail to germinate. These tiny packages of DNA prefer to be kept in a cool, dark place with moderate humidity. Exposing them to heat, light, or extreme humidity levels (both high and low) could result in seeds losing their viability. As long as you source your seeds from reputable seedbanks and store them appropriately, you shouldn’t have to worry about bad seeds ruining your chances of successful germination.
For instance, the upper layer of soil can dry out within 48 hours, making it more difficult to give your seeds the right amount of water they need without overdoing it. Giving your soil too much water during germination could result in the seed rising up or dropping down further, inhibiting its viability. Moreover, seeds that are planted too deep in the soil could experience a host of complications. They could suffocate before coming into contact with enough oxygen, and be unable to access sufficient light to progress into the seedling stage of their life cycle.
There are some techniques that can be used to ensure your seedlings remain in this temperature range. Some growers choose to use special warming mats that can be set to a specific temperature and placed underneath the seedling containers. Another strategy is to place a timed heater close to your seedlings to warm them up occasionally. Once your seeds have sprouted, they will be much more resilient to fluctuations in temperature.
To avoid disappointment, seeds that have a darker colouration stand a better chance of germinating, while pale green or white seeds are likely to fail. Even if dark seeds look slightly damaged, they should be planted anyway. There is a good chance they will still germinate, even if the outer shell is somewhat crushed.
Two or three weeks after germination, your young seedlings should be ready for their new home. At this point you have two options; transplanting them into soil pots, or taking on the challenge of hydroponics. You’ll know when the seedlings are ready to be moved because the root system should start to poke out of the bottom of the wool blocks. As long as the roots haven’t begun to engulf the bottom half of the wool block, they will seek out water and nutrients in their new surroundings and continue to grow downwards.
WHAT TO LOOK OUT FOR IN CANNABIS SEEDS
The dome of the plastic container will create your seeds’ own mini tropical climate. If you then place all the components in a temperature-controlled cupboard, you will have created a self-perpetuating supply of moisture—no need to touch the seeds again until they are ready to be transferred to your final growing medium as a young seedling. Using the stone wool block method, your seeds should germinate in one to two days.
Regardless of where you get your seeds from, it is best to give them a slight (and delicate) inspection before planting. Most of the time, all seeds will germinate; however, poor-quality seeds will produce a weaker plant. Unfortunately, that is something you will not find out until well into the vegetative and flowering stages.
Before you can be met with bountiful hauls of dank buds, there are several stages of cannabis growing that take precedence. Unless you can successfully germinate cannabis seeds, you won’t have a plant to harvest. Give your seeds the best possible start in life by reading our definitive guide to germination.
You may hear the phrase “on and off” in seed germination. Phytochrome Red or Pr is a pigment that will absorb red lights, this pigment is usually found in leaves. However, seeds have also Pr which enable them to react when they will receive light. Under the light, your marijuana seeds will absorb other light’s spectrum which will cause the hormones to release alterations of its biological functions. As a result, your marijuana seeds will turn on and off thus delaying its germination and sometimes will make the seeds dormant.
Water is a requirement for the germination of seeds. Water will give enough moist to your seeds but make sure it will not lead to soaking as well.
Marijuana seeds will require oxygen for its metabolic process. The oxygen will let your seeds breathe properly thus it will support its growth and development under the soil or in any medium you use for germination. This is why its important to make sure the seeds are ventilated and have air flow during germination.
All seeds have desired temperature to germinate. In the case of cannabis seed germination, it has a range of temperature required to germinate. Above or below the range will hinder its germination. 70 degrees Fahrenheit – 90 degrees Fahrenheit (21°C – 32°C).
Why is darkness more suitable for seed germination?
Aside from darkness, there are several factors also which you need to consider to successfully germinate your marijuana seeds. These are water, oxygen, and temperature.
According to experts in the marijuana industry, cannabis seeds are best to germinate if they will be placed in the dark. The main reason why this is effective and true is the fact that light may trigger and act as a hindrance to the germination of your seeds.
This is why seeds have to be germinated in the dark.
