Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.

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.

These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.

Time to germinate

Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.

Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.

If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.

In order to calculate exactly how many cannabis seeds you need, you have to take two determining factors into account:

In this blog, we assume that you buy cannabis seeds for growing cannabis. For this, you can choose between regular seeds or feminized cannabis seeds. Both types differ from each other and have an influence on the final result. The differences are explained below.

Type of seed (regular or feminized)

Reading tip: Our blog about ‘Germinating marijuana seeds’ explains how to optimize the success rate to 100%.

We therefore advise you to take into account an average germination percentage of 90% when calculating the number of seeds you need for your cultivation. This gives just that little extra certainty.

Basically, you need one cannabis seed per weed plant. After all, from one seed a single plant grows. However, it is possible that not every seed germinates. After all, you are dealing with a natural product. It is therefore advisable to have an extra seed on hand.
