App is ballpark start but this is precisely the reason it’s important to learn to read the plants response. Doesnt matter what number’s you have really because depending on genetics, environment, health and age of the plant, source of light etc ideal can drastically change.

Learning the signs is far far more accurate than any meter possibly could be.

With that said they can be a handy tool in replication from grow to grow and learning to read the plants responses
Yeah I've had some bad luck with light so i'm always going back and forth on it. I just need to read the plants from now on

No matter how good you are at reading plants your never going to get on the bubble. A good meter calibrates the eye. You just don't know until you have got honest with yourself.

I have to respectfully disagree. Plants dont care about numbers. There is no ideal number for any specific plant, there are just to many variables… like every single factor from temp to genetics determines the amount of light a plant can utilize and that’s expressed by the plant not a meter.

If I misinterpreted your reaponse then i dont disagree

Yea I get that. It would be pretty crazy if you had to measure the sun everday

Definitely a meter helps taking the guess work out.

Spoton would be my choice of value.

Genetics and proper light strength does wonders.

Enjoy the grow

Don't be rude @Blastfact he was giving you all a compliment. If there was a cheaper meter i'd buy it. I just don't think there is.

There are some members here that use quantum PAR meters from Amazon. Under $200. Search for it here on the farm. I can’t remember anyone really saying anything negative about them.

Idk as a home grower i dont see the need for such equipment. Commercial where data is recorded and used unilaterally across different rooms and facilities it’s important but these meters cannot tell you how much light your plants need only the plants can tell you that.

For the home grower imo its not money well spent and a $20 IR temp gun is far more beneficial as would be a book on the subject of how plants respond to various sources of light and intensity.

This tool is used as a measuring device for records and replication not to determine adequate light under the immense differences if grow rooms. In fact the numbers do not much matter so long as they are consistent. Then you use it to record and replicate it in the future

The only way it’s useful is a ball park to start with until you see your plants limits in YOUR specific grow. The numbers are only truly accurate if you can exactly replicate the grow in which they came from including the exact same genetics.

I cant stress enough that you need to learn to read the plants and these high end tools are meant for replication from grow to grow. Sure you can pay $1000 for an accurate meter but at the end of the day it will only improve your ability to suggest a number to someone under the exactly same conditions (i cant even express how immensely diverse) with the same light and genetics.

Once you figure the plant light tolerance you can record it no matter how off the meter is and use the sane meter to replicate it

OOOO Bull Shit!!! It takes years to master reading plants and knowing ones lights and what they can do and how to use them. And as fast as tech changes I will take all the help I can buy, beg or borrow. Good mechanics use good tools and all the tools they have at there disposal. I would have given my left nut to have this meter in 1975 when I started.
