You may have heard that a light meter is an unbelievably helpful creature to keep your houseplant glad or to aid you in attaining indoor horticulture excellency – almost like a wizardly wand !
But these pecker come with a miscellany of lineament and are available at a full range of a function of cost points – as humble as 15 US dollars or so , and up into the thousands .
So when it comes to using a short meter for houseplant care or other indoor horticulture pursuits , you may find yourself wonder what the difference is between the various options .

And the vaporous number of dissimilar models may allow for you wondering which one to opt .
We link to marketer to help you find relevant products . If you buy from one of our nexus , we may clear a committal .
Help is here ! This clause is go to take the air you through 11 unlike light meter options for houseplant gardeners and indoor agriculturist , explaining the pros and cons of each equipment , so you’re able to easily equate and counterpoint them .
Before we bet at the top selections , let me go over the features we ’ll be examining .
You ’ll rule out about the caparison material , colour , dimension , and weight of each gadget . I ’ll also lease you know which units of measure it uses , as well as its valuate reach .
You ’ll pick up about the display eccentric , how the role model is powered , and – if a battery is postulate for operation – whether the electric battery book binding slither off or requires a screwdriver . ( This last point is a personal pet peeve of mine – I ’m not thrill when I have to find a screwdriver to change out a failing stamp battery ! )
I ’ll also let you know whether the luminosity sensor ( the part of the equipment which observe light ) comes with a protective cap or not , as well as whether the sensor is built into the equipment or separate , attach by a cord .
While some gardeners and growers may prefer a summary , all - in - one gadget with a establish - in sensing element , I consider a detached sensor to be a plus since it allows for more flexibility when taking measurements .
For loose meters with detached sensors , I ’ll countenance you have sex how long the cable length is and whether this cable is coiled or straight . I also look at consecutive cables to be a positive since the spiral ones can determine one ’s reach .
And of course , we ’ll also be face at the various operable features of each example .
We ’ll investigate what type of faint sources can be measure out accurately , such as sunlight versus dissimilar types of galvanising bulbs .
You ’ll also pick up whether each gimmick features some of these vulgar selection : holding current readings , bind tip or low readings , logging data , and calculating a daily light integral ( DLI ) , which give you the mediocre clean photo over the course of one day .
We ’ll also consider the truth or measurement uncertainty of each mannequin . Manufacturers have tested their gadget in this regard and are able to express that the gadget is accurate , for example , within a 4 % tolerance of erroneousness . The crushed the routine , the more accurate the gimmick .
In add-on to these operating social function , I ’ll allow you have intercourse what character of supplement add up with each equipment , and finally , I ’ll give you an thought of what to expect in term of pricing .
Okay , houseplant parents and indoor gardeners , are you ready to get started ? Here ’s a prompt peek at our inclination of selections :
11 of the Best Light Meters
Now that you have an idea of what features we ’ll be research , here are a few interrogation for you to consider when take a light meter to use for houseplant care or other adventures in indoor gardening .
You may want to snap up your trustygardening notebookto jot down the solution before we move ahead .
Do you want to perform a simple curb to verify your houseplants are getting the proper amount of sunshine ? Or are you concerned in a tool that will help you cultivate houseplants or indoor crop under grow lights with the good event ?
The answers to these questions may mold whether you should opt a pricey PAR light metre or an cheap machine that amount in foot candles and lux – or something in between .
allow me flesh out the differences for you .
Some meters use a silicon photodiode to measure out light in foot taper and lux , providing measure that are more apposite to the human eye than to the elbow room plant life practice brightness level for photosynthesis .
They measure illumination , that ’s to say , how much light illuminates a airfoil .
However , these type of wanton meters are unremarkably enough for houseplant gardeners whose plants spring up in the glow of natural sunlight or with the additional luminosity of non - LED grow light .
These machine represent the most low-cost options , and their pricing starts at about 15 dollar .
On the other hand , for houseplant agriculturist or indoor gardeners using a selection of LED grow lamps , a PAR ( photosynthetically active radiation ) light meter run to be a more desirable solution .
These machine display social unit in PPFD ( photosynthetic photon flux density ) , proffer more accurate measurements of the sparkle that plants can actually use than m that measure in metrical foot candles or lux .
That ’s because these meters measure photosynthetically participating radiation – that ’s to say , light that plants can use for photosynthesis . These devices employ quantum detector that count photon – which is something that the lx and foot candle metre do n’t do .
However , PAR devices require a more significant monetary investment , come out at about 150 dollar and blend in up into the thousands .
Before you rise to the conclusion that a PAR light cadence must be the better one for your gardening pursuit , first check the horticultural references you swear on – which light exposure units do they use ?
Foot candle tend to be the unitpar excellenceamong many US - free-base horticulturalists and county denotation program , so if you trust on these source for gardening or agricultural guidance , a time that displays measurements in metrical unit candles may be more convenient .
Of course , it ’s potential to win over PPFD to foot taper , but this is n’t a aboveboard affair , since conversion differs depending on the light source .
You ’ll find a more in - depth explanation of these different types of devices inour clause on how to utilize a lightsome meter for houseplant and indoor gardening . I highly urge reading that guide before choosing a machine so you ’ll know what to have a bun in the oven !
Now let ’s get started with learning about how these different gadget can assist you in your houseplant produce or indoor culture adventures !
