unless you're really lame, the expensive PAR meter isn't going to tell you anything you already don't know, PERIOD I wasted the $400 and didn't learn anything new, except what I just told you.
I wouldn’t buy expensive I got this cheap jump off and it works fine. For around 20 bucks. I’m gonna see how this meter holds up to my buddy’s 400 dollar meter and let ya know the results.
the spectral range that is used by plants for photosynthesis (400–700 nm). A PAR or PPFD meter will help you dial in rich blues, strong Reds, UVB, IR.....
Dam I thought I had a par meter not a lux meter thanks for catching that lolThis cheap meters are great for measuring light,(LUX) or lumens. But PAR (Photosynthetically Active Radiation) reads the Photosynthetic Photon Flux Density (PPFD).
LUX is a measure of the visible light, and that is all it reads. Since, photosynthesis for these plants occurs at different levels of color, you need to measure the Radiation PAR.
***Scien-E***
PAR measures micromoles of photons per meter squared per second (μmol m-2 s-1). This is the power of electromagnetic radiation in the spectral range that is used by plants for photosynthesis (400–700 nm). A PAR or PPFD meter will help you dial in rich blues, strong Reds, UVB, IR.....
Well contstructed paradox .
UVB is below 400nm and IR is above 700
So ,,,no, it wont certainly wont dail in anything like that .
The reading is a weighted average across the usable spectrum . Would only be helpful when testing individual photon flux, from a specific wavelength , by an idividual emitter .
Assuming , of course , you bought the metre specificaly made for LED measurements.
