i think the bubbler is the best for hydro, ive talked to many people from the hydroponics store and online and i hear signle plant in a single 5 gallon bucket with bubbler. this is the set up i use. i run one 5 gallon bucket with a 5 inch rock stone running from a dual line 60 gallon air pump both lines run into a T spliter and run to one rock stone for more bubbles. i use 6 inch net pots so they will grow bigger. i dont use a resi. i jsut change the water every 2 weeks and the plants seem to love it.

here is what i based my grow off of but i dont use floros.

oh yeah and it cost like 20 bucks for each bucket so its realitively cheap
