i think i would be using about 10 buckets total; a couple mothers, and maybe 4 clones and 4 flowering, perhaps less. actually more like 3 flowering, 3 clones, 2 mothers

but regardless, it seems that i can use a dwc setup from clone to flower? that is really attractive; no transplanting, no fuss, and i really like using an individual pump for each plant so i have redundancy, one system failure doesn't kill the crop
