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.

My dog LOVES these !!!! And he’s very picky !
Flavor Name: Chicken
Omg !! My dog is the Pickiest dog on planet EARTH ! He hates every snack treat I have bought for him and I wind up giving all the treats and vitamin supplements to the neighbor down the street who has a dog !!! But he absolutely LOVES these like CRAZY !! And I try to limit him to only a few per day ! But he gives me those puppy eyes, and stands up on his hind legs begging me for 1 more and I always wind up giving in to him !! Boy! He can’t live without these , and I make sure that I never run OUT !!! It’s plain chicken which he’s crazy about , he doesn’t like beef treats at all , so these are excellent for the price point and must be very tasty because he loves them totally !!! It’s a nice long cut stem of chicken , but he devours it quickly , and it comes with a stay fresh packet inside the bag ! But these never last because he eats them up quickly ! The price is very good for the quantity that you get inside the bag ! My dog just loves these !!

Healthy treats
Flavor Name: Chicken, Flavor Name: Chicken
This Chicken Jerky is amazing. You can literally break up the chicken with your hands. I am cautious about what I give my dog but it is the real deal. My Chihuahua LOVES it and he is super picky. Even the price is reasonable and it is a healthy treat.

My dog won't touch anything else
Flavor Name: Chicken
Suffice it to say I have full bags of other chicken jerky treats. They're open. They're also full. She won't touch anything else. She loves Pawmate and Pawmate only.
