Yeah I know. I want hydro because I heard it finishes way faster. That's the only reason. Anyway- if I go with the lucas system I'll want to stock up because the nearest hydro shop is like 3 hours away...

How long do the concentrated GH flora nutes last batch-wise anyway? In order to maintain a 1-to-2 ratio of micro/bloom, I'm going to buy a gallon of the micro, plus another quart container of the micro, and a 2.5 gallon jug of the bloom. About how long/ how many "runs" will this go in a 10 gallon rubbermaid based dwc system?

Or to be more specific, in a 10 gallon tank, about how much concentrated formula (micro and bloom) will be used for a single batch?
