Well, I don't think anybody should just use or not use someone's watering schedule as being correct or wrong. What may work best for one, may kill the plants in the other.

I say this because of differences in temperature, humidity, size of plants.....but most of all in which media you are using.

The settings of say a 2" plant on the ebb and flow table in hydroton, will/should be different for an 18" plant sitting in rockwool.
