Soak your starter cubes in pure, clean water for at least 1 hour and gently shake out any excess water.
Carefully insert 2-4 seeds into each starter cube hole. You’ll want extras in case one or two seeds don’t sprout. In the event they all sprout you’ll be able to choose the strongest of the bunch by thinning out the weakest.
Place starter cubes in your nursery.
Alternatively, it is possible to germinate seeds using zip lock bags. After inserting your seeds, place each starter cube in a zip lock bag with a couple of drops of extra water. Seal the bag and place in a dark closet or shoebox for 3-5 days and your seeds should have sprouted and be ready to move to a grow tray.
Continue to add either water or your diluted nutrient solution directly to your tray and you should start to see sprouts in just a couple of days.
Once your seeds have sprouted you’ll want to gradually intensify your plant light by slowly moving your lighting a little closer each day until they’re no more than 6″ from your plants.
