Product Overview

PhotonTube™ is a new LED tube product line that has its light output tuned to the spectral and intensity needs of growing plants. The T8 PhotonTube™ offers 33 umols/sec of photon output, with spectral coverage across the PAR spectrum from 420 nm to 800 nm.

Because this is a full-spectrum product, the resulting light output is a soft white color that simulates natural daylight, rather than the harsh pink/magenta light color typically seen in grow lights. This makes it easier and more comfortable for you, the grower, to see and observe your plants, and spot any diseases or infestations before it's too late.

Our PhotonTube™ LED grow lights are available in 4000K and 6500K, with 95 CRI and R9 > 80 - this indicates a color spectrum that comes very close to natural sunlight.

These T8 LED tubes are UL Type A and Type B compatible, meaning they can be used with or without a fluorescent ballast. Plug it in directly to your existing T8 fixture, or a new fixture with the ballast removed - whatever is easier!

4000K provides an excellent spectral output for strong growth and flowering. In addition to strong output in the blue 450 nm region, RedBoost red phosphor technology ensures sufficient coverage in the deep red portion of the spectrum past 700 nm, targeting chlorophyll A absorption in particular.

The spectral ratio simulates late-season light, stimulating plant processes that encourage flowering and fruit growth.

The 6500K spectrum comes very close to natural daylight, truly simulating what plants have adapted to over many generations. It is especially well suited for seedling growth, and helps to prevent them from becoming "leggy" as the spectral dosage perfectly matches that of natural daylight.

Plants in the seedling stage require significant amounts of blue light to encourage vegetative growth, as it is similar to a high sun-angle spectral composition that is typically observed in early-season grow periods.

Seedling and vegetative growth are absolutely critical components of healthy plants. Without a healthy foundation, plants can suffer from stunted growth and limited yield.

Fantastic bone for my Lab!
Flavor Name: Bacon, Size: XL - 2 Pack
My chocolate lab loves these!! He is not an aggressive chewer, and so they last a while. I’ve bought them numerous times and keep them on hand. Love that it’s safe for them to digest. Bacon flavor is his favorite. They don’t stink at all (some other brands do), and they don’t make a mess. Fantastic bone for my boy :-)

Fabulous Lasting Chew Bone
Flavor Name: Bacon, Size: Large - 3 Pack
I can no longer get the Deerhorns they loved, so I have been buying these. They are so excited when I open a new package and give it to them. They like all sizes. They place their feet on the handles and hold it, making it easier for them to chew on them. They are a little less expensive if I visit a local Walmart store. The problem is that they are often out or not stocked.

my dog loves it, but is chewing small, jagged shreds off of it
Flavor Name: Bacon, Size: Large - 2 Pack
My dog loves this bone and he is able to easily hold it in his paws due to the shape. He is half bernedoodle and half bloodhound quite large 75 pounds and is a very aggressive chewer. My only concern is that he is biting off small pieces of what I believe is plastic since it’s the nylon one. I know he’s probably ingesting some of the pieces. Is this supposed to happen?
