I'm planning a bubbler hydro setup with four plants. I have two questions: Should I use one rectanlge Rubbermaid container or several 5 gallon buckets? I want to keep it as simple as possible while remaining effective. How much bubble action is needed to feed the roots? Also, I've seen setups with just an air pump and stone and I've seem those with a submersible pump for delivering a steady stream of fluid via tube to the top of each of the net pots. Is this too much solution to constantly flow over the roots? Seems like an easy addition to a bubler system. I wonder if the solution can be atomized through a nozzle and misted throughout the space with a submersible fountain pump. I dont want to go overboard, but at the same time I want to maximize the growing conditions.
