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.
What is germination?
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.
Germination itself is a crucial aspect of cannabis cultivation. The seed germination process is the foundation of every marijuana plant, and steps can be taken to boost successful popping. For example, some cultivators improve germination attempts by soaking seeds in 1% hydrogen peroxide or a compost tea for 12 hours beforehand to kill any dangerous pests.
To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.
After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.
If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.
Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.
Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.
How to germinate marijuana seeds
For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.
A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.
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.
Last but by no means least, oxygen. Just like mature plants, seeds need oxygen to survive. As we mentioned above, the issue with water logging seeds isn’t really too much moisture, but a lack of oxygen. This isn’t the only way growers might deprive their seeds of oxygen. Other common factors limiting oxygen intake include sowing seeds too deep into the soil or a heavily compacted growing medium.
Here is a diagram of a bean seed. Cannabis seeds are very similar, as they are both dicots. A dicot plant is a plant that has 2 cotyledons (the first leaves that appear on a seedling) compared to a monocot plant that only has one cotyledon.
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
With Grobo you can grow from seeds or clones, and our state of the art grow box also reduces smell. Grobo users can expect to grow approximately 2 to 3 ounces every 3 or 4 months.

Exact advice will depend on which germination method you’ve chosen, but we’ve found there are two simple tips that work for all germination methods.
Seed Germination Process
If you’re growing cannabis plants, you’re in luck. Cannabis seeds germinate easily and generally have a high germination rate. Some strains may certainly be slightly trickier to grow than others, but this usually falls more into the vegetation and flowering stages than germination.
It’s worth highlighting, as we have previously, that environment is everything in growing cannabis, including germination, so your environment may move these estimated time frames around slightly. As well as this, whichever strain you’ve chosen to grow will affect the length of time it takes to germinate. For example, sativa seeds usually take longer to germinate than indica seeds.
