Cant justify $1000 on an apogee PAR meter .. am wonder is there a decent meter that will tell me if some LED (SF-4000) are doing what there suppose to ? TIA
Thats ingenious .. THANKS for the link mate !!Making a PAR and DLI Meter Using an Arduino
I’ve been gratefully enjoying the online Greenhouse 101 course offered by the University of Florida. This course inspired me to start measuring the Daily Light Integral (DLI) my plants receive. T…www.google.com
lux is a measure of visible light to humans. PAR is light useable by plants. a 100w incandescent bulb will give you 25,000 lux 12 inches away no prob, doesn't mean its a great for spectrum for growing plants. Also, lux meters can't do blurple lights, par meters can.You don’t need a PAR meter to do what you’re asking. A cheap $30-35 lux meter will suffice. Here’s a little chart you can use to check light intensity.
when mine arrives I'm going to do a thorough check on my SF lights, will def let you know!Cant justify $1000 on an apogee PAR meter .. am wonder is there a decent meter that will tell me if some LED (SF-4000) are doing what there suppose to ? TIA
Look forward to it .. SF4000 ?when mine arrives I'm going to do a thorough check on my SF lights, will def let you know!
THANKS .. good to knowlux is a measure of visible light to humans. PAR is light useable by plants. a 100w incandescent bulb will give you 25,000 lux 12 inches away no prob, doesn't mean its a great for spectrum for growing plants. Also, lux meters can't do blurple lights, par meters can.
That being said, if you know your light's spectrum and trust the manufacturer lux is a good approximation. But unless your fixture is throwing out a lot of "white" light, lux meters will be waaaaaay off.
