This guide is regularly reviewed with new insights on cannabis seeds and growing.
Cannabis seeds themselves are freely available in the Netherlands. Growing is more nuanced. In principle, cultivating cannabis in the Netherlands is prohibited, but home growing of up to five plants is tolerated, as long as you voluntarily hand the plants over when the police ask. In Belgium, one plant is tolerated. Professional or large-scale cultivation is punishable and is dealt with severely. So stick to the rules and inform yourself well beforehand.
Next Level offers a wide range of cannabis seeds. Broadly, they fall into three types, each with its own characteristics.
| Type | Feature | Handy for |
|---|---|---|
| Autoflowering | Flowers on its own regardless of light hours, often within a few weeks | Beginners and anyone wanting quick results |
| Feminized | Genetically bred to produce almost only female plants | Anyone who does not want to sort out male plants |
| CBD | Specially bred for a higher CBD content | Anyone who prefers CBD-rich varieties |
Autoflowering seeds came about by crossing Indica or Sativa plants with the Ruderalis variety. The latter comes from regions with a short summer and therefore flowers automatically, regardless of the number of light hours. The result: a fast-flowering plant that is easy for beginners to handle.
Feminized seeds are genetically adjusted to produce almost exclusively female plants. The sex of a regular cannabis plant only shows at flowering and is determined by the X and Y chromosomes; feminized seeds take that guesswork away. Finally, CBD seeds are bred for a higher content of CBD, one of the best-known cannabinoids. Want to know more about those compounds? Read our blog CBD, THC, HHC and CBG explained.
Fresh cannabis seeds keep for about a year, provided you store them cool, dry and dark, preferably below 18°C. Freezing is possible, but after longer storage, thawed seeds often lose part of their germination power. For the best result, use fresh seeds where you can.
There is a lot of confusion about germination. It is actually simple if you follow a few steps.
Tip: A cannabis plant lives only one season: it germinates, grows, flowers and dies within a year. So plan your grow for the right time of year for the best result.
Once you are past germination, the real work begins. For the next steps, and the most common beginner mistakes, we have separate guides: growing weed indoors, growing weed outdoors and 10 common cannabis growing mistakes. Not sure which seeds to choose? Read our cannabis seed buyer's guide.
