I'm sure i could get some cheaper than what i got, but both mine got replaced under warranty, so i now have 2 brand new shiny digital ballasts
my nutes and PH should be buffered by my LARGE resivor that will be constantly pumping nutes up (and they will drain down into it) its an AERO set up and I'm putting in a 4" drain hole for roots to grow down. or maybe i'll do a Shallow deep water culture (SDWC) with a similar recurculating set up..
does it still seem like it wont work? I'm definatly going to have some issues with this new set up(like I always do), I just hope i have thought it out enough
