drip systems are easy, and u can use them with soil... u'll need play with it to figure out what the right amount of drips/water/time the pump needs to stay on. but u basically take a gallon of water, add ur nutes(try not to feed with every watering) say ur going to need 3-4-5 gallons, get a 5 gallon bucket, do each gallon individually, and dump it into the bucket, place the hose and drip sticks into the soil, and turn the pump on... its the best and easiest way to water mass amount of plants, once set up, u just add water and plug in the water pump untill it drains all the water in the bucket. they're cheep too for wat u get out of it... u could prolly assemble it completely for 50-100$ the pump will be the most expensive and go big, as ur going to need 60-80 drip ends, depending of if u want to keep a few to water manually... im sure its only going to become more and more of a hassle as those plants mature.
