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.

Durable and fun
Flavor Name: Beef, Size: Medium/Large
I have two dogs and I only bought one bone over a month ago. They’ve both been chewing on it and it’s held up really well. I wouldn’t say they’re aggressive chewers, but they do like chewing.
They’re still picking it up and using it, so they’re definitely not bored with it. As for me, it’s been a pretty great buy.

Tough Chew!
Flavor Name: Original Jerky, Size: Medium
Sporn is a very tough chew. We have a 22pound Beagle 1 year old. She spend little time working on the Hard plastic that encases the marrow. Now I don't doubt there are some dogs that would chew this mindlessly for the small marrow treat. It is not for my pup! She needs more play to keep at it. A TOUGH CHEW would be better slightly less thick and more marrow inside. I attached a string and had her whirly birding around chasing this bone but once we let go she has a 30 second interest. Not for every dog maybe for the big guys 100 lb brutus !

Dogs are enjoying it!
Flavor Name: Beef, Size: Medium/Large
I just got this bone today but so far my dogs love it. They have been playing with it and alternating who’s chewing on it. My 8 month old got the blue rubber piece off in about 10 minutes, so if that’s the primary factor for purchasing, note that.

lasted 3 days
Flavor Name: Original Jerky, Size: Medium
I have a 10 m.o. Aussie who is in chronic chew stage. I was hoping that this bone would last longer than Benebone. Watching pup chew her little heart out, I noticed she was tearing off little pieces of the plastic bone and swallowing them.
Threw out. Wish I'd returned. NOT RECOMMENDED FOR SUPER CHEWERS

I like it, but
Flavor Name: Wishbone, Size: Large
Two large dogs, two different experiences. They both loved the toy, but one chewed it up within a couple of weeks - much longer than most toys last for him. The other one still loves it and uses it daily,(has had it for two months) but if I don't trim off the sharp points that form, it gets blood from his gums on it. Would still recommend it as each dog is different. Worth a try.
