Seedling growth begins once the seed has popped from its shell. Using the proper medium, the seed is placed with the root facing downward thus causing the leaves to grow upward. When done properly, the roots will not only act as a feeding source but will also anchor the plant into the medium creating a strong base. In this stage it is important to give the plants the proper amount of light per day to achieve maximum growth. Too much light is as bad as too little.
