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.

Favorite Handy Toy
This snake has been around our house for years! My shitzu/maltease dog is tiny, and he has a small mouth, but I call him Diablo! He loves to growl and act like a horrible terror when it comes to fighting over a little squeaky toy, and we use the snake to try to "push" the little toy away from his mouth. He loves to bite the snake and pull on it viciously. The snake has tiny holes in it, but has pretty much stayed intact. I am getting ready to add more stuffing inside it so it won't be so floppy. years of use have flattened it out. I love this thing. Well worth the money for a small-mouthed dog. The squeaker in the head was fun while it lasted, but the beauty of this snake is its shape and versatility as a pull on, and sneak up behind toy.

Fantastic Toy!!!
Pattern Name: Duck, Pattern Name: Duck
16 squeakers!! Every one works! Best toy I’ve found!! At 71yrs, I’ve had many dogs. Many toys. Rocky couldn’t be happier. Which makes me happy! It’s a bright yellow duck, kinda flat. 16 squeakers!! Big, for my 5.5 lb Pomeranian, but, he’s all boy, so, it’s great. He won’t leave me alone!! Play time, and, looking in my eyes with all the love he feels for me…. I’ll buy every toy this company makes, just to get that look from my pup!! Sturdy, so far. Beautiful orange and yellow colors. Soft toy. I love it, myself!! The box says it’s a 27 inch toy. So….its a 27 inch toy. Yes…for the many squeakers, I’m gonna hunt for more from this company. Rocky and I are having a Ball with this toy!!! A great bonding item for us. And, I enjoy seeing my boy’s eyes sparkle. I would do anything for Rocky!! Thank you, Amazon!!!

Wonderful bunny toy
Pattern Name: Rabbit
My dog is totally obsessed with this bunny! She loves it so much. She doesn’t chew it up or squeak it which is strange but she packs it around with her everywhere she goes. She is lab pit mix and usually chews toys to shreds in a few days but not this one!

Miki destroyed this toy in 30 minutes
Pattern Name: Duck, Pattern Name: Duck
I like the fact that it had several squeakers & was longer than most toys. He played with it for less than 5 minutes & here it lays on the floor. He has absolutely no interest in it & that is not the way he normally acts with a new toy. The money wasis a waste, but the fact that he has no interest is a big disappointment. I could not recommend this toy for any dog. This toy was put away from lack of interest from Miki when we got it. I got it out the other day & I am adding this info because it is important for pet owners to know how much this is a danger to your animal. ThMiki tore the stitching in the head in a few minutes. I stitched it up & let him have it back. He proceeded to destroy this toy. This lead to squeakers coming out along with stuffing. In the title of the description it says -No Stuffing Plush Pet Chew Toys- also this is supposed to be for medium to large dogs. I can sew him a toy much safer than this one. Please read this review & do not purchase this toy. I really can't give this a 1 star as it really is a zero.
