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.
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.
So you know how many cannabis seeds per pot, but you want to know what will happen anyway?

How much light a plant receives is highly variable. When growing outside, it all depends on where a plant is located to receive the most light throughout the entire season. Weed plants like full sun—at least six hours of direct sunlight every day. If a plant is in the shade or gets shaded as the light changes throughout the season, it can affect yields.
Some regions get rain early in the fall, so you’ll want to grow plants that are ready to harvest by the beginning of October. In tropical climates, you can practically grow weed outdoors all year round.
When growing indoors, you’re often limited by space—a plant can’t get as big in a grow tent as in a big, open basement. You’re also limited by how powerful your grow light is. For example, Leafly editor David Downs harvested 150g from one indoor plant with one 200W Black Dog LED light. The company said that light maxes out around a half-pound of buds, or 224g.
Indoors, it depends on how powerful your light is. A small 200W LED is great for a small grow tent, but you’ll need something bigger for a bigger space, which also means a more expensive light.
Different soils have different nutrient levels and some nutrients can promote plant growth. You can also add nutrients to soil or water to help plants grow big and strong.
A weed plant will lose about 75% of its weight to moisture loss and trimming after being cut down. A considerable amount of moisture leaves the plant during the drying process, and trimming removes all the stems, branches, fan leaves, and trim from the plant.
Many factors affect how big a plant gets, but generally speaking, if you are growing a healthy plant, you can expect these yields from one weed plant:
However big your plant gets, you’ll likely have more flower than you know what to do with. Many people will save a certain amount of flower for smoking, and make edibles, concentrates, and other weed products with the rest of their harvest.
Certain weed strains grow big or tall or are high-yielders simply because of their genetics. Traditionally, indicas grow short and stout, and sativas grow tall and lanky. That’s not always true across the board, but it is a good rule of thumb.
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.
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:
Pros and cons of growing autoflower
Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.

But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.
