I use bubblers and that's fine. Look at my thread. 5 liters buckets(i realize that's it's too tiny), air stones, little netpot with rockwool cubes, GH nutes, lot of air in the water, 600 HPS/MH depending on the flo/veg state, and a lot of wind with fans(Special thanks to HARDON). And GH nutes, quite a lot. I'm going to be using 1.5 liters of each with 16 plants in 2 grows. For the next grow, i will be using biggest buckets but connected together to enhance the management of the level of nutes. The plants don't drink the same amount of water every day and it's a hassle to check every day every bucket.
