Avoid These 9 Mistakes when Germinating Marijuana Seeds

By  //  May 16, 2021

Marijuana is renowned for its rich history and is widely used for various purposes. Whether you use cannabis for medical or recreational purposes, you can now grow a few plants at home.

Moreover, you can acquire quality seeds, thanks to the many seed banks available. There are blunders to avoid, though! And you should understand the germination process for excellent results.

Where can I get quality cannabis seeds?

You can get weed seeds from accredited marijuana dispensaries. But, most people rely on weed banks for supplies. There are various weed banks online that stock a variety of strains. The common types of seeds available are;


■ Feminized

■ Autofloweing

Moreover, most seed banks offer tons of information on genetics and germination. If you’re a first-timer, inquire about the best grower seeds for starters. You can also Shop on Seed Supreme, to get the latest marijuana news and free seeds on all orders.

How can I recognize quality seeds?

The quality of seeds determines the type of plants and harvest. It’s crucial to grow from top-shelf genetics, and there are various ways to assess quality seeds. The color and feel of the seeds tell a lot about maturity and germination potential. Greenish seeds are immature and won’t germinate. In case they grow, they take longer to mature and won’t produce the desired yield. 

On the other hand, dark brown seeds are of high quality and will grow to form healthy plants. You’ll find such seeds at leading seed banks and you’ll realize that they also have a shiny gloss on the surface. Moreover, they don’t crack or crumble when pressed between fingers. 

The seeds come in varying shapes and sizes, but this shouldn’t bother you. Some strains produce smaller grains, and it’s common to get seeds of different sizes from the same plant. Therefore, don’t discard tiny seeds or those in different shapes. 

What are the mistakes to avoid during germination?

Using the wrong soil mix

Most people use soil from the home garden or backyard. This isn’t the best, and the composition is unknown. Still, the mix may not have the right nutrient balance, which affects the overall germination and growth. Know the soil composition before planting your seeds, and consider loamy soil. It’s rich in nutrients and oxygen and offers excellent water retention.

Leaving the germination medium to dry out

Once you place the seed on a moist medium, the germination process begins. Various processes take place during this stage leading to germination. No matter the substrate used, don’t leave it to dry out. Your seeds will lack adequate moisture, which affects the overall growth. Check the growth medium daily to ensure that it remains moist. Moreover, be keen if you use a heat source to achieve higher temperatures. It might as well dry up your growth medium.


 Moisten the disc to make it swell, but don’t drown it. The idea is to keep the disc moist during the entire germination process. If you overwater the jiffy, you drown the seeds and prevent adequate ventilation, which stops germination

Improper planting

Weed seeds feature an oval shape with a crate and crown. When growing the seeds, the crown should face upwards and the tip facing downwards. Upon germination, the crown acts as the hinge, and the tip will open to let out the root. Most people do this wrongly, which makes the taproot grow upwards and the seedling downwards.

Germinating in the soil directly

Most people grow directly into the soil, resulting in non-germination. For instance, if you sow the seeds before watering the substrate, then water afterward, you’ll bury the seeds deeper. For excellent results, germinate in a paper towel, peat plugs, or pellets and transplant to the soil or pot once the seedlings grow. With this method, you can germinate many seeds in a tiny space, making it easier to offer the right temperature and humidity.

Extending the germination period

It’s also a mistake to leave the seed for too long when using kitchen paper for germination. Don’t let the seeds germinate and show cotyledons. If you allow this to happen, transplantation will be a challenge, and you’ll likely damage the root. 

What’s more? Don’t expose the root to too much light and air, making it wise to transplant the seeds before this happens.

A quick tip: Transplant the seeds when the taproot measures about1-2 cm. 

Low temperature& Humidity

Seed Supreme supplies high-quality seeds but they only germinate under the right temperature and humidity. You may have to use a heat source to offer about 26-28 degrees temperature during some seasons. Also, you need about 70% relative humidity, and lower values lead to slow or unsuccessful germination. 

Similarly, too high temperatures and humidity can result in fungal and rot problems. Your seeds won’t germinate when exposed to changing temperatures. Maintain the right levels and keep them stable until transplantation.

Wrong planting depth

Most growers plant the seeds too deep, which makes the seeds not to emerge. On the other hand, when you sow the seed close to the surface, they will germinate but will have weak stems. The stems will also bend and won’t allow the plants to grow properly. However, you can avoid this by sowing the seeds at 2 cm deep. Once the seedlings emerge, cover the stems to enhance stability and allow the buried part to grow more roots.

Too many seeds in a single pot

Growing too many seeds in one pot limits their growth potential. The seedlings compete for nutrients, light, and space. As we all know,  light plays a vital role in cannabis plants, and too many seedlings in a pot translate to minimal yields. The plants will also produce minimal lateral branching and weak stems, which affects the overall yield. Moreover, limited space will restrict the roots, which isn’t advisable for weed plants.

A quick wrap up

Germinating marijuana seeds is fun and, at the same time, challenging. But you must understand the growth process to grow healthy plants and produce high yields. For outstanding results, buy your seeds from accredited seed banks, water your seeds rightly, and maintain correct light and humidity levels.
