If you're going to use rockwool, make sure you're presoaking the cubes in a correctly pH'd solution before adding the seeds. Again, I don't use rockwool, but if I remember correctly you want the pH of the cubes to be somewhere between 5.0-6.0. Or, if you wanted to skip the rockwool altogether, you could go out and buy a seedling starter mix that will contain little-to-no extra nutrients, and will sustain the seedlings until they're ready to be moved into more fertile soil.

Best of luck. :jointsmile:
