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.

The perfect soap bag for me
I'm new to using soap bags, I've tried a few different brands so far and this one is by far my favorite. I love how soap bags create a rich lather with bar soap while exfoliating but the ones I tried before this brand were way too rough to use on a daily basis, my skin would be red after showering. When I saw the type of material these soap bags were made of, it looked to be more gentle so I decided to give it a try. I've only used the white soap bag a few times now but I love it. It fits my Dove soap bar perfectly (other soap bags were too large), still creates a nice rich lather and best of all the material is so much more gentle than the other soap bags I've tried so I'm able to use it regularly without feeling like I'm scraping my skin off. I was hesitant to buy these due to the lack of reviews but I'm glad I did, with how amazing this product is I hope more people find these and try them out. I plan to buy a few more packs in case they ever stop making these, the price is very reasonable as well.

sub-optimal design
Size is a bit too small for anything bigger than an average bar of soap, so the soap doesn't move around enough to make good suds. the inside is also too textured, and the soap sticks to the inside of the pouch. good quality and sturdy stitching however.
