I'm thinking about getting a rubbermaid 10gal dwc system and runnung the lucas system on 4-6 plants under about 10,000 lumens of cfl light in a closet space... About how much GH micro and GH bloom would I need for one batch? How many batches could I expect to finish if I bought a stockpile of 1.25 gal GH Micro, and 2.5 gal GH bloom?

Thanks for any help.

i dont know bout the lucas method but i would suggest just a two part nute setup just go basic for now.... then up grade later im on the new pura vida two part organic it can be used in hydro no cloging i use it in dirt and works fine....

i was using FF but was soon disillusioned. GH 3 part with Latewood's recipe has been working well for me. I'd suggest doing that. you can start with distilled water, GH flora series and calmag and you're good to go

good luck
