Hey guys, I am considering getting a quantum par meter. Does anyone have a good chart or table that shows the par reading recommendations for each stage of growth? I can't seem to find any good ones. Thanks!

Hi folks. I've played about with differing spectrums etc over the past couple years but don't have a PAR meter. I really want one as I'm going to build from scratch but...... The reason the thread title says light meter too is that I'd like to be able to measure from IR down to UV. These will...
