There are many soils advertised as germination soils.¹ They are basically the same as other soils, except that they contain special blends of micronutrients and are kept somewhat clean (the soil is sifted and no compost is added). Ordinary loam soil with a pH of 7 and an NPK (nitrogen, phosphorous, potassium) ² of higher or equal amounts of N than P or K is good for starting seeds. Even NPK ratios of 5:1:1 or 8:4:4 are good. Just make sure that the N is equal to or higher than each of the P and K factors on the label.

After the next few days the first set of leaves will appear. Don’t let your medium get dry and try to get your plant some light.

Some substrates are actually developed with seedlings in mind (low or absent in nutrients). They are usually called seed starters.
