Lux and Par Meter

[olschool]

hey all im kinda a gaget guy and looking for a lux/par meter what would anyone recommend?

I haven’t tried it yet but I picked up a uni-t with Bluetooth that connects to an app. Was only like 35 or so.

I use an iPhone app and it works great

yeah i have an app on my phone but there is so much glare on it the values change as i put it so i can read it

There are apps for smart phones, some are OK some are out to lunch
The big problem is the absence of a cosine corrector (white dome).

Par meters are expensive and all the cool kids use them
Lux meters are cheaper, the band they are measuring is different than the par band (but not a lot different). That’s what I’m using…

I’ve had pretty good luck with the UNI-T Light Meter UT383BT and the app “ppfd meter” pretty solid little unit and has a very affordable price tag. Make sure to get the Bluetooth version “BT” if you purchase… otherwise no app functionally with your phone.

Can confirm. I got one in the last few weeks, cheap and easy to use.

Great tip, I am looking for one and wasn’t sure this would be ok.

I’m using this with qb led’s

And I use the following as a guide…

Hope it helps!

Helps a lot since I don’t even have a lux meter, I think I might want to get one.
But really looking for a affordable and with a near source so I can get it fast because I get anxiuos with web shopping.

Thank you!

I have the same one, I find the separate sensor slightly annoying as you need both hands.
Doing it over, I’d look at one with the sensor attached to the body.

I suspect that the higher readings I’m getting might be ‘compressed’ somewhat. I find the last couple grows the plants were hitting max. light around 45~50K lux causing me to suspect that the meter response might be ‘non linear’ but as @Jetdro pointed out to me, it’s really all relative.
Your meter reads the same value, so you can adjust accordingly.

Honestly, I use it more for the seedlings and at that time i set the lights 21" away. After a couple of weeks I just wing it. Now the meter needs a battery replacement…
During flower, lights are set usually 18" above the canopy and I continue to increase based on stretch. Dimmer set to 50%.
I’ve noticed that in my tent, plants that are short or further away from the lights are able to get their buds just as dense as their taller counterparts. Like u mentioned, it’s all just relative.
It’s good to have the device. Just to know things…
