There are a few indicators that will give you a sense of whether the seed is worth germinating.

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:
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
Are you ready to grow?
This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:
To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”
Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
How weed clones work
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.
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.
If you’re looking to grow a plant of this size before June then you’ll need to grow it for at least six months so the plant has more surfaces to flower on, which should take another three months. You’ll get much better results if you plant straight into the ground rather than pots.
Taking care of plants for such a long time is quite a lot of work for the grower, you need to keep an eye on infestations, fungi, nutrition, transplants, pruning, tutoring… The whole process takes about six months of constant work. If you’re looking for a decent product and yield, you’ll need:
Many people aren’t really sure when to plant their crop. When’s the perfect time of year to germinate your seeds so that everything runs as smoothly as possible? Well, this depends on what medium you’re growing in, the accessories and things you have at your disposal etc. You can grow the perfect crop at any time of year depending on how you’re doing it and what you have. Today we’re going to show you techniques so that you can get the absolute most out of your plants regardless of what time of year it is.
If you’re looking for small plants (1m 250g +/-)
Then, you’ll need to make a hole around 50x50x50cm and fill it with new substrate so the plant has a decent medium to grow in. Once your plant has germinated and it’s a few centimeters tall you can officially move it to the greenhouse. You’ll need to install a light above the plant that should turn on for 10 minutes every four hours or twice a night so that it still grows during the winter. The light doesn’t have to be super powerful, the only reason we do this is to annoy the plant and keep it growing. Once the plant reaches around 40cm, you’ll need to start pruning it starting with the main calyx. Two or three weeks later, prune again on the higher branches, two weeks later another one… until after a couple of months you have a big ball of leaves full of mini-calyxes which will later grow into long branches.
When spring arrives we all know that it’s time to start germinating your marijuana seeds for your outdoor crop. It’s the most important crop of the year as it’s where you can get the most production of the entire year. Old school growers like to plant their seeds for the first full moon of March.
The best thing to do in this case is to wait another month or two; a germinated seed in a decent climate from April onwards will actually be bigger and better grown than one planted in March in the same place.
If you’re looking for normal marijuana plants (2m 500mg +/-)
The reasoning behind this is so that while your seeds are germinating they’ll also have light at night time and they won’t stretch up too much in their first days of life. Sometimes it’s a bit too cold at that time though, and of course you can’t plant at the same time everywhere, we’re talking from a Spaniard’s point of view here. If you live somewhere with a very cold climate your plants will take much longer to grow and they’ll get stressed out from cold or wind, which will create weaker plants that are more susceptible to infestations and fungi.
To be able to grow it for so long you’ll need to do so in a greenhouse. You’ll need to buy or make your own plastic greenhouse. In a greenhouse your plants can avoid the cold during the winter as well as receive enough light to grow properly. You’ll need to germinate your seeds in December. You should germinate them inside so that they don’t die off at the start and they can get a nice warm germination.
