Hey geronamo

Letting the water run out of the bottom of you pots is a good way to water, just be sure to let the soil dry out properly before watering again.
Roots need oxygen to grow and overwatering (too frequent) will drown them.
A good rule of thumb is insert your finger into the soil to check if its dry enough. I use the weight of the container to tell and that works fine for me.
Put a link in your signature to your grow so others can see it also.
