Light Meter Reading

[HallieReusch]

It's really pretty straight-forward, actually.

Thank you! This was very helpful. I wonder if they make a light meter that measures PAR...

What lights are you using? From the photos, the color spectrum looks purple, meaning that they appear to be plant grow lights (red/blue spectra).

I ~think~ THIS is the one I have.

Never that! But if you're going to spend the money on a light meter, you might as well gain some ridiculous entertainment for it!

Are you up to 80 plants yet?

Haha, fair enough! Getting there! We are moving in a few weeks, so I am trying to hold off on buying any more!

Not a stupid question at all. The problem is(was) many of us in bonsai are ignorant of the terminology and particulars of measuring light like people who are into photography. Post #9 helps us all. (Well, maybe @sorce will still be staring at the moon...)

oOo me wants to read post #9. How do I find it?

They do! I was just getting ready to mention that I’m not sure about the Lux levels, when starting trees indoors I’m concerned with the PAR levels more than how much light it’s putting out. I bought one one eBay.

Are you having issues with your plants? Is that why you’re chasing this info?

On the right side of the post...

Check out the product info brochure. Notice the spectral graph, as well as the reference to PAR generation:

Not necessarily. I just want to get a better idea of the care I'm providing (or lack thereof, LOL). I'm sure there is room for improvement.
