marijuana seed germination 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.

Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.

GERMINATION TEMPERATURE PLAYS A CRUCIAL ROLE

Small, fragile, and in desperate need of a helping hand, there are several ways you can germinate your cannabis seeds. All methods have varying degrees of success, with both advantages and disadvantages. It is important to note that even with advanced growing expertise and top-of-the-line equipment, you may still end up with a few failed seeds. This is a natural part of dealing with a living organism. At Royal Queen seeds, we only sell feminized cannabis seeds, so there is no need to worry about removing male plants.

You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.

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.

For indoors: The same but under a grow light, fluorescent or LED. If you have the option of germinating your cannabis seeds inside your home, ideally the light intensity will be high; the less intense the light, the more the seedlings will stretch in search of light and become spindly. If you use a 400 W light ideally it should be 40-45 cm away.

– Another advantage is the specific temperature: water has a low specific temperature. This means that if we place a glassful of water in a room at 25°, it will be very hard for the water to reach that temperature. Therefore, if we place the cannabis seeds in a very watery medium (a glass or between paper towels) the temperature will be lower, while in a Jiffy, as it is more exposed to the air, the temperature will be higher and the process, faster.

Now that you know how to take your first steps, you’re ready to start this season’s crop. Have a good harvest!

Differences between cannabis and hemp

Today you can find high quality products on the market, specifically designed for germination and which, in addition, are not expensive. What do you need?

– Jiffy 7 is expressly designed for the mega-industrial production of seedlings and does not require fertilisation.

However, there are people who germinate marijuana seeds in paper towels. Why don’t we recommend them? Well, although this method may be effective, it is not the most adequate and has some disadvantages. To start with, the seedlings do not receive the necessary light, as the paper towel that covers the top prevents the sun’s rays from penetrating. In turn, in the Jiffy they do receive light, and therefore photosynthesis will start earlier. Another advantage is that as soon as the root emerges in the Jiffy, it starts to turn downwards and to absorb nutrients: on the one hand we accelerate the process and on the other, when we replant the Jiffy 7 with the seedling there is no transplant shock.

Ventilation is an important factor; don’t make the greenhouse airtight, open the trapdoors to allow adequate ventilation and as the covers are made of thin plastic, you can even make some extra holes if necessary.

There are several possible ways to germinate Cannabis seeds; here we describe the most important ones. At Royal Queen Seeds, we only sell feminized cannabis seeds, so it’s not necessary to eliminate male plants.

By placing the seed in a moist culture medium, it begins a series of reactions that will lead to germination in a few hours or days. Whichever substrate we choose for germination, we must ensure that it never completely dries out, because as the seed stops absorbing moisture, it’s likely that the seed will cease its activity and never germinate.

Things to know in brief

Another common mistake, in this case when germinating in kitchen paper or similar, is to let the seed germinate until the cotyledons appear. If we do this, then the subsequent transplant is very difficult, and it is very likely that we’ll damage the root in the attempt. Additionally, the longer the root is exposed to air and light, the more damage will result, so it is preferable to transplant it before this occurs.
