Before you re-water...

Well I was wondering, before you would re-water your plants how many centimeters would you feel for dryness before you re-water your plants? If you dont understand that I'm asking after you water your plant how many centimeters would you dig in your soil for the dryness off it before you re-water the soil?

i use pots w hole in bottom so just stick my finger up through there to fell how wet it is

I usually judge by the plants' vigor ... just a visual assessment ... when the soil dries, thats when the plant draws up its nutrients, it's an important stage ... :smokin:
