Just picked this up on Amazon.
Looking pretty good so far. Spend all day with this testing my ChilLed lights as well as the SF4k I have. While it does not match the par charts exactly, its only off by about 10-20 ppfd. Not going to say that its as good as the apogee, but for anyone that is looking for something to get you close, Im pretty happy with this purchase. YMMV.

I have been looking for a par meter. Iam new to led's and it seems an accurate par meter is very helpful if not required. Are you still liking your purchase? $60 is is very cheap! Is it still accurate with repeatable results? Thanks for your review.

The OP hasn't been here for a while. Does anyone else have experience with this unit? I am suspicious of it's quality. I usually believe you get what you pay for but if it is 95% accurate to save hundreds it would be worth it.

I use the photone app on my iPhone and it gives me a really good reading because I have compared it to the LED charts for my light. But to be honest I don't even need to use an app to get good readings now because lumatek offer an exact distance for each tent size.

Why do think you need a par meter ?

Just to verify how much light at the canopy? I bought 2 marshydro fc-8000's for a 5x9 tent. They put out massive amounts of light and I don't want to fry my plants. I have 0 experience with Led's so I wanted to be safe and learn how far to dial down power or adjust distance. Am I over thinking it?

I wasn't planning on it, getting a meter, but when I saw 1 on Amazon for $60 it seemed like a good idea. Not spending $500+ on an apogee. So I was hoping some had experience with the 1 on Amazon.

I did get the photone app. I just wasn't sure how accurate it really would be.
Its good to know it is fairly accurate. More reason to not spend alot on one.

Does mars not have a reference chart in the book that came with it? A ppfd map?

It shows you how to calibrate it to your light using the ppfd chart for your light (the photone app). I've been using it this grow and I had way to much light on my girl. Since you have a meter coming maybe you can test it against the app and let us know if the app is somewhat close

No charts in the manual. I have been researching alot, maps from you tube testers, migro & coco for cannabis. 24" without co2 is a very nice par map. But if I can dial it down a bit and keep it a little closer, there for more efficient and cheaper to run?

I have not ordered 1 yet. The op has not replied to my question of his experience with this $60 unit on Amazon. Sounds to me like I can use the phone app with acceptable results, so don't think I will bother unless I start having issues.

Yeah if you can calibrate it to the par map for your light. I haven't used the app without calibration so don't know how accurate the default is.

The spot on par meter that migro uses now, instead of the apogee, is about $390. It does the standard 400-700nm.
The newer apogee sq-610( I think thats right?) does 400-750nm to help determine how much far red and ir you are getting. $600+
