temperature to germinate cannabis seeds

Place one sheet of damp kitchen towel on a flat surface. Space your seeds a few centimetres apart before placing the second piece of kitchen towel over the top. You need to ensure both pieces are damp, not wet. Once again, when the white root tips reach 2–3mm, move the seeds (carefully) to soil pots. Use the same guidance found above for planting techniques.

Often overlooked, it is all too easy to assume that the vegetative and flowering stages of cannabis growth are the most critical parts of the plant’s life cycle. However, with the chance of failure high unless you know what you’re doing, poor planning when it comes to germination can make or break your next grow. Giving your cannabis seeds the best possible start on their journey to bulging buds is a surefire way to encourage a healthy and robust plant.

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.

GLASS OF WATER APPROACH

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.

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.

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.

If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.

Outdoors we never know what dear mother nature has in store for us; in the same way that your seeds might enjoy a week of good weather and sun, there can also be thunderstorms and low temperatures on the very day they sprout. Not to mention the large variety of birds, snails and other fauna that delight in eating those tender and tasty marijuana seedlings. Bear in mind that during their first moments of life, your plants are defenceless against many dangers that threaten them; therefore, it is your job to take care of your little ones and keep them safe. How? It’s actually quite simple, you can buy mini-greenhouses for germinating or you can use a Tupperware and make holes in it for adequate ventilation, although we recommend the first option.

– It is sterilised, meaning that we prevent the appearance of fungi (powdery mildew, botrytis, etc)

Step 2: choose quality materials.

You can germinate your cannabis seeds both indoors and outdoors, though our recommendation is that you do it indoors, as you will have more control over all the factors that can have a negative effect on the process. But if this is not, below we explain the best way to germinate seeds outdoors.

– It has all the elements necessary to nourish your seed/seedling during the first week; the ideal amount of nitrogen, phosphorus, potassium, calcium and magnesium. Phosphorus and calcium are particularly important for the correct development of roots.

– On the one hand it has the ideal structure, that is, the amount of air and water in the substrate is adequate for germination.
