faster and more efficient than what? my setup easily handles 16 plants. i only fill res with 6 gallons of water to keep the oxygen levels high. my plants are small. Not sure if you were criticizing mine or not but i said i grow small plants. if he is asking these starter questions i take it hes not flowering 20 monsters. check them out. started feb 17 from seed. 26 days old today. look good to me? if no critisizing then check out my pics. the other tub shows the max size youd prob want to go with the plants in that tub. The clear tub works amazing! its clear for demo only. plus it makes no diff if you change your res when your supposed to. every 5 days! lol
