2. Mushroom cultivation

The mushrooms commercially grown in Thailand each have different environmental requirements that must be met if maximum production is to be achieved. Some varieties may require more darkness or more humidity than others. Others may need high temperatures and/or windless conditions for maximum production, while still others are relatively insensitive to temperature and/or wind fluctuations. Nonetheless, all varieties of mushrooms require that growers follow certain common steps in order to successfully cultivate mushrooms. These steps are as follows:

1. A pure mushroom culture is developed in a Potato-Dextrose-Agar (PDA) mixture from a mushroom spore of the desired variety;

2. "Mother spore" is prepared on a grain substrate;

3. The mother spore is propagated on organic material, and;

4. Mushroom spawn, commonly referred to as mushroom "spore," is planted and cared for in such a way as to achieve maximum production.

(Note: Mushroom growers in Thailand rarely complete steps 1, 2 and 3 as the PDA, mother spore and spawn of the commonly grown mushroom varieties are easily cultivated and sold commercially at low cost. Therefore, local growers might only complete step 4.)
