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.

Love them
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.
