Seeds are germinated in small units inside a seed or clone propagator: a tray, of sorts, designed to help plants germinate. One such kit is called a rockwool SBS propagation tray.³ At the bottom of the tray is a small area where water or germination hormones can be poured. Small grow cubes called rockwool cubes are placed into slots in the tray, which automatically dip the rockwool into the solution. The seeds are placed into tiny holes in the cubes (the holes are filled with rockwool particles to prevent the seeds from being directly exposed to air in the environment) and the cover is replaced. Some propagation kits are even heated and look like miniature greenhouses.

This method has a very high success rate, however a disadvantage is the cost of the tray, rockwool, and grow fertilizers. You should note that, although some seedling fertilizers contain growth hormones mixed into the nutrients in order to promote plant growth, it is recommended that you not use fertilizers or growth hormones with your seeds unless you have experience. Even the slightest amount of overfeeding can kill your seeds or burn your seedlings. In fact, you are better off just using water in your propagation kit to germinate your seeds. I have yet to find a cannabis strain that needed growth hormones or fertilizer to germinate properly. The price of the tray is about $10, the rockwool cubes $5, the grow fertilizers $5. If you have spent upwards of $50 on good seeds, why not spend the extra $20 on getting a small kit like this together and increase your chances of achieving a 100 percent success rate? The kits offer the added advantage of being able to root your clones.

You do not have to use soil as a medium to start seeds. There are many seed starter kits out there like this rockwool seed kit.
