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.
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.
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.
In addition to the type of cannabis seed, nature always has an influence on the germination process. After all, the cannabis seed is a natural product and this means that not every seed is viable and germinates.
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.
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.
In order to calculate exactly how many cannabis seeds you need, you have to take two determining factors into account:
Within a week or so you should see a seedling begin to grow from the soil.
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
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.
However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.
For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.
CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.
