I was recently at my local hydro store and the guy turned me on to this free magazine "maximum yield" its free!Althought its not aimed directly at MJ there is very uefull info in there, i recently read a chart in there that can estimate your electric bill for any size light. I found it very usefull, if your interested in hydro growing and have no clue where to start, start by picking up this magazine. Its awesome!
