In order to calculate exactly how many cannabis seeds you need, you have to take two determining factors into account:
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.
Type of seed (regular or feminized)
Reading tip: Our blog about ‘Germinating marijuana seeds’ explains how to optimize the success rate to 100%.
Auto flowering seeds are basically feminized seeds, but have the advantage that they flower automatically (read more about the difference between feminized cannabis seeds and autoflower seeds). However, feminized seeds are more expensive than regular seeds. Depending on your budget and growing skills you will choose the type of weed seed.
From experience, we know that 93% of the cannabis seeds grow into a plant. This is of course a very high success rate, but not 100%. So you will have to use extra seeds in order to have the certainty of eventually becoming a weed plant.
You can save money on planters, soil and marijuana nutrients. But, in practice, there is just too much that can go wrong.

How Many Cannabis Seeds Per Pot?
If you have a planter with two plants and one turns out to be a male you’re in a real bind. You can kill off the male, sure.
Do you know of any more situations that would require more than one cannabis seed per pot?
This makes the fight for root space meaningless.
