so i set up my drip system with a 50 gal res. did exactly what the store person said. and im still having problems. when i water the plants for 15 mins to half hour. once every two days. after the watering im left with a soaked floor. 1/2 inch deep of water. and the soils still dry as hell. i replaced the drip heads with adjustable ones. (slower/faster drip) but it still does the same wether faster or slower. how do i get it right to where i saturate the soil witout ending up with a wett floor and dry soil.. im confused.
