It all depends on plant size, soil porosity and structure, plant age, growth stage, ambient temperature, %RH, light intensity, and amount of air movement.

There's a formula for all that, but I don't feel like looking it up...

You might be able to find it on the web somewhere, but in the meantime, it's easiest to water when the pot feels light.





HAHAHAHAHA!!!! had ya goin. :D just pick up the pots!
