The amount of oxygen needed by a particular type of plant varies. Some plants will not germinate even in the presence of moisture unless air is also present. For this reason, most seeds should not be soaked directly in water for days on end, but transferred to a better-aerated environment after a day or so. Moist seeds will germinate at temperatures between 68 and 86°F, with 75°F being ideal for many plants. In cold settings a heating pad might be used to raise the temperature of seed trays. Some seeds germinate better in light, while others prefer dark conditions—research the type of seed to learn which it prefers. 94 Maximum Yield USA | March 2012
