Description

Take the guesswork out of grow lighting! Measure PAR / PPFD, lux, fc, and kelvin: All within the most accurate light meter app out there.
Setting up your plants' optimal lighting is not easy, if not impossible without a proper PAR / PPFD plant light meter. Calculating your indoor garden's daily light integral (DLI) to match your plants' needs allows you to optimize your lighting for maximal yield at minimal electricity consumption.
Our Photone grow light meter app measures photosynthetically active radiation (PAR) as PPFD in µmol/m²/s, calculates the daily light integral (DLI) in mol/m²/d, and measures illuminance in foot-candles or Lux. It also allows you to measure light temperature in Kelvin which can help you determine if a light is suitable for fruiting and flowering or for vegetative growth.
Photone is by far the most accurate light meter app for plants and achieves industrial grade accuracy that easily compares to dedicated and very expensive quantum PAR sensors. You can learn more on how we achieve ±5% accuracy compared to research grade laboratory equipment and how to achieve maximum accuracy by yourself in our white paper: https://growlightmeter.com/whitepaper/
The Photone app also contains useful guiding articles to help you get the most out of your plant lighting. In addition, you can find more informative and educational content on our blog: https://growlightmeter.com/blog/
Wondering how much light your plants need? The plant lighting calculator on our website helps you to dial in your lighting to your specific plants' needs: https://growlightmeter.com/calculator/
To ensure an accurate light intensity measurement (e.g. PPFD, DLI, lux, fc, …) , you need to select the correct light source that you are measuring and use a diffuser. Some common light sources are already available for free while others may need to be purchased additionally. In this way, we are able to fund our development efforts and offer the most accurate light meter app out there without annoying ads. For the diffuser you have two options: easily build one yourself for free or get the easy-to-use Diffuser & Cosine Corrector accessory from our website (-> lightray.io/diffuser).
Our Photone Pro subscription enables you to access all supported light sources, measure light color temperature in kelvin, additional pro features, access additional resources for better results in plant growth, and receive our premium support – and there's even more to come in the future!
The subscription is auto-renewable and automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal at the price listed within 24 hours prior to the end of the current period. Subscriptions made on iOS devices can be managed and auto-renewal turned off in Account Settings for your Apple ID after purchase. Once purchased, refunds will not be provided for any unused portion of the term. But no need to worry, you may cancel at any time.
You can find our terms of service on our website: https://growlightmeter.com/terms/

Photone Reviews

Useless unless you pay

Hanso216 on

Canada

This app requires you to select a “lightsource” for it to work. The app is free. However, the light sources are not. So if you wanted to measure a space that has sunlight you would need to pay for the “sun” light source. Waste of time and money.

Disgusting prices

Student oil on

Canada

Idc how accurate this is, 7$ CAD for ONE type of light detector is absolutely filthy. Why anyone would spend that much on an app like this is beyond me but big nope from me. Actually disgusting that this is what the app marketplace looks like now, bunch of scams hiding behind a ‘free app’. Either make the app 7$ or whatever but that’s way to much for INDIVIDUAL settings. Pay 7$ for specifically white LED and another 7$ for blue LED instead of making it 7$ for any LED. Again, absolutely disgusted by this, it’s dystopian af : (

Shouldn’t be advertised as free

dorsler on

Canada

The functionality you get with the free app is next to useless, as the light sources most people will be using are locked unless purchased. So people should provide their reviews for the app that’s advertised (the free one) rather than the pro version, which should be rated separately. Many reviewers reviewing the free app have obviously purchased the pro version, so their reviews don’t really count.

Great App for Indoor gardeners

I Love This App it's Perfect for See How Much Light your Plants are getting. PPFD,Lux,D.L.I,Kelvin.On Some phones you may need a Stripe Of White paper

Does what I need.

Works like a charm.

Demo requires payment

fastalanca on

Canada

The second step in the demo of the app asks you to select the light source and most of the sources are locked. You can’t even select sunlight or LED. How do they expect you to buy it if you can’t even try it?

Impressively similar to quantum sensors

Titty lo mein on

Canada

Tested the app against a 500$ hydrofarm quantum sensor and as long as your light diffuser is properly attached, your readings will be identical

A bit pricey

Pierretest on

Canada

Without paying...difficult to compare. Should offer few days trial for all light. I didn’t see an option ...one price for all light type. Conclusion: Forget this app

Good meter

luvdawige on

Canada

Accurate and you get fc ppfd dli readings without any effort. Helps me adjust my light through out the seasons. This is a must get for indoor gardens.

I highly recommend it!

Davestunnedyou on

Canada

It’s close enough to a dedicated PAR Meter which costs way more. Helped me a lot about window/grow light positioning.
