If you are low on space, you might consider putting a male clone and a female cannabis clone in the same pot.
Germinated seeds with sprouted roots will sprout into the seedling stage more often than not.
Unless your planter is HUGE, your plants are going to be fighting over nutrients and root space.
Multiple Seeds in One Pot
There is one time that putting two cannabis plants in one pot might make sense:
Another cheap alternative is 5-gallon paint buckets—that have never had paint in them of course. So, unless you plan on breeding two plants, stick with just one seed per pot.
Since you won’t have to worry about separating the plants, this could work.
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.
With feminized cannabis seeds, you don’t have the risk of a flowering male plant. Because female seeds produce 99.9% of a female weed plant. This is why most growers choose feminized seeds or autoflowering seeds
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.
So, what if you plan to grow five plants and one or more seeds don’t germinate? Then you won’t achieve the intended yield, and you have to purchase seeds again. It’s therefore wise to use several seeds per plant.
With regular cannabis seeds, the genus of the plant has not yet been determined. When choosing regular seeds, the chance that the seed will develop into a female plant is about 60%. The chance that the seed develops into a male plant is therefore 40%. And because male plants do not produce buds (read: marijuana), you need several marijuana seeds to increase the chance that you will eventually grow a female plant.

Autoflowering 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.
In order to calculate exactly how many cannabis seeds you need, you have to take two determining factors into account:
If you are growing from regular cannabis seeds they could also cross-pollinate resulting in buds with cannabis seeds in them. It sounds simple enough but if the buds have seeds inside them, the potency of the strain can be reduced up to 30%. Each cannabis seed is a plant and they need their own space to grow and thrive, as well as to produce bigger and better buds. Remember that more than one cannabis seed per pot is too many.
If you have ever wondered how many cannabis seeds per pot, look no further. One seed is all it takes to grow one plant so even if you see plants that look like as if they were bushes it is all just one seed. Regardless of the apparent size of the plant, all growers know that only one cannabis seeds per pot is required.
If you use more than one or many cannabis seeds in a pot, the cannabis plants will begin to compete against each other for nutrients, so the smallest cannabis plants (which sometimes may be the best phenotypes.) will get wiped out by the bigger cannabis plants.
So you know how many cannabis seeds per pot, but you want to know what will happen anyway?
