This is my first post/comment...Great site and want to say thanks for all the help you people put out there.OK then,LED'S,they do work,beyond what I thought they would do....back in the 80's we had and still do MH and HPS.I've been out of the field for a long while, 27 years[divorce,other reasons],tired of BS out there on street market in my state. Decided to try something myself/very small.It got bigger real fast!...Have some odor problems.Working on it.Peace everyone!Love to everybody!
