The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis 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.
Preparing to germinate cannabis seeds
Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.
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.

You will find the most precise details from your plant pod package as well as from our plant list here.
The Smart Soil creates the perfect environment plants need to thrive. It releases nutrients in sync with the plant’s life cycle, keeps the soil’s pH balanced, and employs tiny oxygen pockets to guarantee that plants get ample breathing room and nutrients even when the soil is wet.
Usually it takes 1 to 2 weeks to germinate. Some plants such as mini tomato , chili pepper and rosemary may take up to 3 weeks. The lettuce plants are very sensitive to high temperatures so their germination might be inhibited by that.
Germination speed mainly depends on the temperature of your room. The warmer the environment, the faster the germination. The best average temperature to grow your plants is 18 to 24’C (64 to 75’F).
Please make sure you keep the transparent germination domes on the pods until the sprouts reach them.
Further, if using a Grobo Start alongside a Grobo Solid or Premium, you can expect to have an additional harvest per year as it speeds up the process.
Let’s get the jargon out the way first. Simply put, germination is the development or growth of a plant from a seed or spore, usually after a period of dormancy (like if the seeds have been sitting in a jar to store them). It’s also known less scientifically as sprouting. During this process, your seed will crack open and sprout a single root, known as a tap root, before beginning the growth stages above the soil.
Success in seed germination is actually quite straightforward as there are only three factors that really matter: water, temperature, and oxygen.
Germinate Seeds With Grobo
Firstly, clean hands. We carry loads of dirt, oils, and other gunk on our hands. If you must touch the seed when planting it, make sure you’ve washed your hands first. However, if possible, it’s preferable to pour the seed straight from the container it came in directly into your chosen container for your germination stage to eliminate this possible contamination. You could also use small tweezers to move the plant.
We have no doubt you’ve probably already read tons on the huge amount of germination methods available to pick from, like the popular paper towel method or the arguably inefficient glass of water method.
Ignoring the environmental factors listed above, germination rate is most influenced by how long the seed has been dormant. The seeds with the highest germination rate will be those planted within a year of being harvested from the mother plant. This is because they are newer seeds, and are more viable.
Depending on the seed and the environment, a general rule of thumb is you should see signs of germination within 3 to 5 days of moisture being introduced to the seed and, if your germination method allows, you will be able to see a white root tip within this time frame. If you’re using soil in your germination method, as you won’t be able to see the root appear, you won’t see a sprout until roughly 7 to 10 days since first beginning your germination process. Many gardeners will germinate seeds on a damp paper towel in a ziplock bag. This method allows you to see the root start to develop, and also works quite well.
