BALASUBRAMANIANC you can buy tubes locally and attach it as extension to the pump. if all outlets in same level then increase the water duration to double. it should easily cover 10 to 12 plants. remember original pressure is distributed to 4 additional plants, so it will be slow, but increase the duration of watering to compensate for pressure so that plant gets sufficient watering. it's a trial and error process only for extension. worst case 10 plants can cover. best case 12 plants.abive suggestion , take it with a punch of salt.

BALASUBRAMANIANC use the day set to 1 for daily watering. and set the seconds to number of seconds of watering. say 80seconds. the time at which you set say 9:00 am in morning the above settings. it will daily repeat at same time daily for 80 seconds
