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?

mspofford032579 Reviewed by mspofford032579 on . Best butrient system for beginners Hello. I'm considering a first grow using a rubbermaid based dwc system and about 10,000 lumens of CFL light in a cabinet. I'm trying to get some feedback on a good nutrient combination for beginners. Something not too complicated (if there is such a thing) and somewhat forgiving (again if there is such a thing- I realize this isn't easy at all). I've read great things about the "lucas system" and it sounds awesome, but I'll be honest- I'm a cheapskate, and GH's flora series isn't cheap. Rating: 5
