25' of 1/2" soaker hose has always worked well in my 4' X 8' raised beds. It delivers about two gallons of water per foot of hose per hour. I use a single timer on a main line which goes to each bed. We have experienced a severe drought since November so I have the timer set to water six minutes in the morning and six minutes in the evening. Since we have a water well, I prefer to keep my beds moist (not wet). I've found that by watering only around the individual plants, earth worm activity and fungus growth is restricted in the beds. The soaker hoses encourage both in the entire beds. I also have almost no bare ground in my raised beds so it would be difficult to install emmiters for each plant.
I am using 1/4" drip emmiters in some containers. At this time, I am using single, 1/2 gallon per hour emmiters for each container. As the plants grow, I may need to add additional emmiters to each pot. The drip system operates on the same timer as the soaker hoses. With the current timing sequence and duration, each pot gets about one pint of water per day.
