This slideshow covers how to make a simple seed germinating mix using coconut coir fiber as the base ingredient. The finish potting mix can be used for both seed starting and adding ingredients to for making potting on mixes for older vegetable seedlings as they grow their way to transplanting.
All ingredients are measured by volume not weight. When 1 part is mentioned, it can be any size measuring container that is suitable for the amount you are making.

Coconut coir comes in different size blocks and bricks. This slideshow show how to prepare and make a seed starting mixture using a common 650g brick. As a personal preference perlite is used rather than vermiculite.
This is your base mixture that can be used to add other ingredients as the seedling grow and are re-potted.
