What is Reddit's opinion of Light Meter PAR Meter Up to 400,000lx and 6000umol/(㎡s) DLI Calculator Lux Meter PPFD Tester?

From 3.5 billion Reddit comments

lux measurements are worth nothing. spend an extra $60 on a PPDF meter from amazon, this is the cheapest one. if you're gonna spend the next 4 months on these plants, it's worth being able to test that you're getting them the most PPFD possible.

since you will be using two lights, any sort of PAR or PPFD measurements of those posted on any websites go completely out the window. those are only accurate with one light. things change drastically with more than one light. it's not as simple as doubling the hight or halving the power or anything.

i would highly suggest picking up a $60 PPFD meter from amazon. at only 200 W you'll likely want to keep the lights pretty close to the canopy. how close? nobody can tell you since you have more than one light.

don't buy that. that measures lux which is not helpful. you need a PAR or PPFD reader. the cheapest one is $60.

aim for as close to 1100 PPFD as you can evenly across your canopy.

You really need some way to measure par to be able to know how close to put the light. There are apps for your phone that measure light, and you can buy a cheap bluetooth par sensor on amazon that links to an app on your phone.

if you buy a PPFD meter you can check this yourself.

when you're using 2 lights, all the manufacturer published PPFD/PAR maps go out the window. you need to grab a PPFD meter and adjust the lights until your canopy is as even as you can get it.

Or you can get a grow light. I use something like this to measure the PPFD my indoor plants are getting and adjust the lights according to what is desired for plants. Looking up online you should be shooting for a PPFD of at least 300 for pepper plants, closer to 500 or 700 if you want flowers/fruit.

I got this recently. https://www.amazon.com/Light-3000umol-365-780nm-Tester-Illuminance/dp/B09BMR1SMF

It seems quite a bit more sensitive and I assume accurate compared to the phone app one I tried. Bare in mind this is the cheapest parr meter out there I could find. So far I'm very happy with it. Don't bother with something that just reads lux/lumens

I saw you replied to another of my previous threads btw. I purchased this Light Meter PAR Meter Up to... https://www.amazon.com/dp/B09BMR1SMF?ref=ppx_pop_mob_ap_share it may not be dead accurate, but I’m sure it’s better than the guessing Ive been doing lol.

Cloth pots. Only water when the soil is dry. Follow the instructions on the nute bottles. More is not better. Too much of anything will kill your plants, not make them grow faster or bigger. Weed is a pretty resilient plant so you must be really going out of your way to kill it. What are you doing? Watering three times a day with double nutrients? Giving them 2000 par light? In veg stage they should only be getting watered every other day, at most, and around 500 par of light. Do those buckets have holes in the bottom for water to drain? If not, make holes. Cloth pots are better, tho. When growing, follow the KISS rule. Keep It Simple, Stupid. Write down on a sheet of paper your routine and parameters. For example:

Watering: Monday, Wednesday, Friday.
Feeding: Monday, Friday.
Temp: 70 - 80 degrees.

18/6 light cycle.
Par: 400 til flower, then 800 until finish.

By writing down your parameters, you can more easily make yourself stick to them. Do not break your own rules. Do not mother your plants to death.

Amazon now has a bluetooth par sensor that pairs with your phone and allows you to dial in your exact light levels. It is pretty easy to set up and decently accurate.

Oh, and this is in a 3x3 tent with a fabric pot and a viparspectra xs2000 roughly 24 inches above the pot. Using a cheap meter, I had the ppfd at ~250 until I fed, at which point I bumped it up to ~300

There is a app called Photone that is pretty accurate.

this is what i use and works just fine. this is the cheapest option that measures PAR/PPFD. lux meters are cheaper but you don't want lux measurements.
