This Full Spectrum Quantum meter device is equipped with a waterproof sensor. It is used to gauge the flux of Photo Synthetically Active Radiation (PAR) within the wavelength range of 400 to 700 nanometers (nm). PAR indicates the crucial spectrum of light essential for initiating photosynthesis in plants.
Plants harbor pigments known as chlorophylls, which capture photons falling within a particular range of wavelengths. These photons serve as the requisite energy source for photosynthesis, the process through which plants convert light energy into chemical energy, thereby fueling their growth and development.
Utilizing a Quantum Meter to measure PAR flux allows researchers and horticulturalists to evaluate the intensity of light conducive to photosynthesis. This data is important in horticultural research and the monitoring of plant physiology, as it enables the optimization of growth conditions, the maximization of photosynthetic efficiency, and the assessment of overall plant health and productivity.

Edging made easy
Size: 9 inches
Surprised how well this works.
I was looking for no cord for long driveway. The battery takes a bit to fully charge, but lasts for the entire job. The levels for depth make edging around d flower beds or raised beds easy- not really a trench, but gives a good edge.
Lightweight and easy to manage. Definitely lighter than my corded edger.
The blade is sensitive and the guide to keep it steady along concrete is not great- just need to make sure you watch closely or it will spark when it hits the concrete.

Works well, a little under powered
Size: 9 inches
Works well, a little under powered when I used it for the first time. Once you get the groove established it works great to maintain it

It’s junk
Size: 9 inches
Deserves a zero. Like some others said on here, it runs for 3 seconds and just stops with battery fully charged. I got it for Christmas so too late to return. More China junk.

Great price, does a good job
Size: 9 inches
I’m mostly old. School when it comes to yard equipment. A gas engine has got to be better than a battery .
I have a weed eater that will take out a tree but makes a lousy edger.
Since I don’t have a large lawn, I gave this guy a try.
Turns out it does a pretty good job.
Can’t beat the price and it’s simple to use.
Be aware, this vendor sells the unit only.
They have no spare parts and you will need to source replacement blades. ( they supply 1 spare). Otherwise, worth a try.

Not too bad for the price
Size: 9 inches
I was skeptical if an edger as cheap as this one would do the job at all. I figured if it worked at all it might be worth the price. I was surprised be it is actually pretty good. I have a medium sized area. Just one driveway and about 30 feet of sidewalk. I will use it four or five times a summer and I expect it will last for a few years. It hold a charge enough for my needs. If you have a large driveway or plan on using it every day, you will probably be disappointed. But if you have a small area to do, its not bad.
