Specific amounts of water for growing.

[BobBong]

another says to water untill the water drains out the bottom do this every 2 days.

That sounds much more reliable and less likely to give you moss growing on the top of the soil medium.

I've always understood that having a consistantly wet medium is a BAD thing, for seedlings, vegging plants and flower.. If anything as the plant grows you spread the watering out even more.. going from 4 or 5 waterings a week down to two or even one watering a week with a larger plant.

The larger the plant, the more water it's going to be absorbing.

Watering so that water comes out of the bottom of the pot would also ensure that the roots are growing down and using as much of the soil medium as possible.

A consistantly wet soil medium with seedlings can cause what's known as "damping-off".
