temperature to germinate marijuana seeds

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.

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.

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

Differences between cannabis and hemp

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.

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?

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.

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

At a minimum of 26 degrees, you then check daily whether the hemp seeds are still moist or whether they are already beginning to germinate.

Cannabis seeds, like most other seeds, germinate with normal plant soil. Sufficiently moist and warm, they only start to germinate and grow over time to a beautiful plant. A hard shell protects the soft core of the seed, which consists to a large extent of moisture and nutrients. Thus, the seed survives a prolonged cold spell without it being damaged. Here you will find out how you can germinate the valuable cannabis seeds:

Once the seeds germinate, gently plant the germ down. 5 mm deep turned out to be optimal.

We’re talking about media temperature not room temperature!

Germination is the first stage of the cannabis growth cycle : the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth.

It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.

What is germination?

So, you’ve decided to grow your own cannabis plants. You purchased a pack of seeds, assembled cultivation materials, cleared a space in your garden, and are ready to grow your first cannabis crop . With everything in hand, it’s time to begin the very first step of cannabis cultivation : germinating seeds.

Use a spray bottle to moisten the paper towels and then store the cushioned seeds between two plates, under a face-down bowl, or gently place them in a plastic bag. Maintain a temperature of about 72 degrees Fahrenheit, keeping the paper towel wrapped seeds in the dark and away from a windowsill. In two to five days, the seeds will pop inside the paper towel sandwich and emit tiny roots, ready to plant when they reach about five millimeters in length.

Soil is an easy, more natural method with which to germinate your cannabis seeds because the soil protects the fragile roots from any interference. Photo by: Gina Coleman/Weedmaps
