So you’ve decided you want to grow cannabis. One of the most important and earliest decisions you’ll make is which seeds to use. A good seed contains the essential ingredients for a healthy, potent plant. Learning how to choose cannabis seeds doesn’t have to be complicated – learn the basic facts here.
How to Choose Cannabis Seeds: Buy or Grow?
Seeds should be kept in a cool, dark, dry place. Do not expose seeds to sunlight or they may sprout. Do not expose seeds to moisture or they may sprout as well. Seeds should be stored at room temperature. Exposing the seeds to extreme cold or heat could damage the seed so that it can never be used.
Whether you grow your seeds or purchase them, you should take a few precautions to keep them safe until you are ready to grow them. If done correctly, you can store marijuana seeds for several years and still use them to grow healthy cannabis plants.
It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
Within a week or so you should see a seedling begin to grow from the soil.
Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.
Most seeds that you will buy are regular seeds as described above, but here are a couple more types.
One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.
With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.
