All growth processes within the seed are chemical reactions activated by the addition of water. To develop successfully, the seed needs an increasing quantity of water, and the compost must be capable of holding these amounts.

As all the processes involved are basically chemical reactions they will obey normal physical rules, the simplest of which implies that the higher the temperature is raised, the faster will be the rate of the reaction. In practice, this means that the warmer seeds are kept, the quicker they will germinate. As all these reactions are taking place in a biological context, there are biological limitations as to how high the temperature can be raised. In practice there are also economic considerations, because high temperatures are costly to maintain. Experience suggests that a germination temperature of 21°C/70°F is a reasonable compromise for most flower and vegetable seeds, and this is why an airing cupboard is an excellent place for seeds to
