Incorporating irrigation weather automated or not has one of the highest rates of return in a cultivation operation. The advantages of hand watering are not quantitatively significant and it is my opinion that that it does not serve a purpose past perhaps being used for mother plants. Irrigation can be incorporated into your grow in a step program to minimize upfront cost all the while decreasing overhead at each step.
