  • The seed must be uniform in shape & color as specified on the label but typically dark seeds having shades of black and grey are preferred.
  • The seed must be viable and possess vigor.
  • The seed must possess high germination percentage (Minimum 90%)
  • The seed must be certified from the Seed authorities.
  • It must mention Source & Origin of the seed on the pack.
  • They must have tags for their resistance against pests and diseases (if any).
  • The name of the variety must come up front on the label.
  • There must be sufficient Moisture levels in the seeds (5-7%).
  • They appear like wax-coated, shiny, and reflect light when exposed to sharp light.

If you aren’t finding the best place to buy marijuana seeds according to the above-listed features, you can have them from the growers or friends around but make sure to arrange a “Floating Test”.
This test can easily be carried out with a glass full of water and placing the desired seeds on the water surface, gently. The seeds that keep floating on the surface after a couple of hours are not desirable and need to be rejected. The sinker seeds keep down to the bottom and are worth germinating. You can conduct this practice with the entire sowing stuff and proceed with the sinkers for a better germination percentile.

How to germinate the Sinker Seeds?

The sinkers seeds need to be buried into the growing media for their germination. The 420 seed bank advises to use Cocopeat or Coco coir for this purpose. The growing best Marijuana seeds have 4 basic requirements. i.e. moisture, heat, air, and a dark place. The simplest and a professional approach is to soak seeds in water before putting them into coco coir as you did for the Floating test. Nursery tray or a 4 inches pot is best for a single seed. Fill the pot with growing media and place these seeds 2 cm deep into the media. Apply sufficient moisture on the surface and cover it with a dark shield. Place them in a dark place by maintaining a temperature between 70-90°F and apply little moisture daily. It will start sprouting after 3 days and the entire sprouting process may take 7 days but more than 80% germination must complete after 5th day.

When to transplant the germinated Seeds?

After the weed seeds have germinated successfully, they need them to be transplanted to a place that keeps them going for the rest of their life. The 420 Seed bank advises to avoid frequent transplanting and avoiding the use of different pots for the different growth stages. The ever first transplant out of a 4 inches container is 8 to 10 leaf stage and transplanting to a place where it must complete the rest of its growth until maturity.

What are Feminized Cannabis Seeds?

Feminized Cannabis seeds are capable of producing buds only while this character is induced by the breeder who keeps female plants either monoecious or hermaphrodite that is not capable of cross-pollination within the existing strains. Generally, the Best Online Seed bank offers seeds of feminized varieties along with Cannabis auto-flowering seeds and high CBD weed seeds but it is in the best interest of home growers to continue with Feminized Cannabis seeds as there are no fears of further seed production. Feminization involves a complex procedure of Rodelization which only a breeder can handle otherwise stress can lead to flower any feminized Cannabis seeds that you may figure out at the end of its growing season.

What are Autoflowering Cannabis Seeds?

These varieties are sensitive to daylight and start flowering when they are exposed to 12 hours of light per day. Generally, it regards to the end of their active growing season as the plants attain maximum maturity up to this stage and start producing flowers. Autoflower varieties have less potential than Feminized strains with the only advantage that you can take regular and longer harvests from these strains. Read – Best Autoflower Strains.
