darker seeds vs lighter seeds marijuana

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.

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℃.

One of the most common reasons seeds fail to germinate is because they are simply duds. Typically, healthy cannabis seeds should look a specific way and be of a specific colour. Viable seeds will appear round, not flat, and should be a beige to dark brown colour with subtle tiger striping. Seeds that have been flattened or are pale in colour may have a tough time sprouting into healthy cannabis plants.

TEMPERATURE PROBLEMS

Germination is where the magic begins. Cannabis seeds must first germinate in order to sprout and begin their journey as living, breathing plants. However, if the germination process is done incorrectly, or is thwarted by some other variable, seeds can fail to sprout, leaving you with useless, spent seeds instead. Here are the top five mistakes to avoid when germinating cannabis seeds.

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.

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.

Many people choose to germinate their seeds using paper towels. However, others choose to do so directly in soil. Of course, germinating your seeds in soil isn’t inherently bad, but it can come with its own set of challenges, and is generally not recommended unless necessary.

We do not recommend taking the size or shape of a seed into consideration as a sign of its quality. Some strains simply produce smaller seeds than others, and sometimes the same plant can produce seeds of different sizes and shapes. Never discard a seed just because it is smaller or of a different shape than another one.

A quick web search will bring up all kinds of myths about how to tell female cannabis seeds from males. One of the most popular ones comes from a chart showing 5 different seeds that claims that the female seeds have “a perfectly round volcano-like depression at the bottom (from where the seed was attached to the plant).”

Can You Tell The Sex Of Cannabis Seeds From Their Appearance?

We hear this question all the time from clients and beginner growers, and the answer is a resounding no. There is simply no way to tell the sex of a cannabis seed just by looking at it.

Some smokers might be pleased to see some cannabis seeds in their bag, and might think themselves lucky. However, finding seeds in a bag is bad for various reasons. For one, this means the grower has messed up and allowed their female plants to be pollinated by an invading male. When flowers are pollinated, they stop producing THC-containing resin and divert their energy toward producing seeds. Secondly, the seeds will have added to the overall weight of the bag, which means less weed for your buck.

Mature cannabis seeds usually have a hard outer shell that can vary in color from very dark (or almost black) to very light grey and may have tiger-like stripes. You should be able to firmly press these seeds between your fingers without damaging them.

While all cannabis seed is not identical in color, there are some consistencies. Healthy, viable seed will be light to dark brown in color. Seed that is light green or even whitish in color is underdeveloped and should be tossed out. Healthy seed will also have a burled or turtle shell-like pattern on its seed coat.

Quality seed will be firm. Cannabis seed should have a strong seed coat protecting the pre-emerged life inside. Any seed that is tender, pliable or squishy should not be planted; poor results will follow if attempted.

Why is darkness more suitable for seed germination?

This is why seeds have to be germinated in the dark.

• Water
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.
• Oxygen
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.
• Temperature
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).
