Seeds
After sprouting seeds and putting them into peat pellets I usually put the peat pellet into a plastic cup full of a good veg. soil. I let the roots grow until they fill the cup and then I plant them into a bigger pot, this pot can be a little bigger or could be your final pot size. Your soil is the most important part of the process. If you let the sprout grow out of the peat pellet, plant peat pellet deep enough so the top of your plant is only about an inch out of the soil, or plant the new plant so the stem is covered by the dirt up to the top of the plant. This will help develop a nice root system, hope this helps
