PAR/Umol meter

I plan to use to map out my room, any recommendations will be appreciated.

I only use mine to check on bulbs being old and wearing out.

I run 1K HID's at 6 ft centering. I over lap light footprints that way and can have a non stop line of plants, if I so choose. Good for SCROG or SOG. Plenty fine for not too.

That's another one of the reasons I want one.

I run quantum boards a little hotter than I should, but they are great. Because I run them hotter than I should, I would like to make sure that everything is still optimal.

I use mine to adjust the height so that I can maintain a consistent intensity. It's just as important as my pH pen.

Do tell, what do you guys use?
