Different RED: BLUE Ratio


The PHOTOSYNTHESIS absorb the light with wavelength ranged in 380nm-760nm, among which the 610-720 nm and 400-510 nm are the absorption peak area.

 The 660nm deep red and 460nm blue LED light combination will give plant suitable growth light. The combination will visually produce pink light.

 The Blue wavelengths encourage vegetative growth and are essential in lighting for seedlings and young plants during the vegetative stage of their growth cycle, especially when “stretching” must be reduced or eliminated. It also stimulates the production of secondary pigments which can enhance colors and is known to also stimulate Terpene (i.e. fragrance) production.

The Red light affects phytochrome reversibility and is the most important for flowering and fruiting regulation. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production. The 660nm wavelength has a very strong photosynthetic action and also exhibits the highest action on red-absorbing phytochrome regulated germination, flowering, and other processes. Most effective for light cycle extension or night interruption to induce flowering of long-day plants or to prevent flowering of short-day plants.

For different plants can adjust the RED: BLUE rate to get the most proper light for the plants.

The light RED: BLUE rated at 3:1, 4:1, 5:1 are good to accelerate the growth of leaf, for plant-like Cabbage, Lettuce, Spinach and so on.

The light RED: BLUE rated at 5:1, 6:1 is good for the plant that needs light fill in the whole growth period, like the Leaf Succulent.

The light RED: BLUE rated at 7:1, 8:1, 9:1 are good to accelerate the growth of root, for plant-like Eggplant, Tomato, Long Bean, Color Pepper, Cucumber and so on.

Tips for Installation:

* The height of the luminaire from the plant
4-9 Watt: Between 30-70cm, ensure covering all plants with light.
9-18 Watt: Between 50-100cm, ensure covering all plants with light.

* Reference fill time
It is recommended to add 12-14 hours of light a day. It can be flexibly determined by the plan growth phase to determine the time of the light.

Needs to outgas for a day or two and then its great.
Size: Queen (Mid Loft), Number of Items: 1
Needs to outgas for a couple days, ideally outside on a clothes line. Having said that its the first pillow out of a half dozen Ive bought in the last 18 mos that I can sleep on. Sleeping much better and longer now. Latex foam is the only pillow for me. I swear I searched on here a year or so ago and could not find one.

Goldilocks pillow
Size: Queen (Mid Loft), Number of Items: 1
I tried 5 different latex pillows, 2 from this brand. Most had to much loft and were too firm. This brand has one called extra soft that was comfortable but a little too soft. BUT, I could tell the latex was better so I tried this one. It strikes the perfect balance of support and is not too firm. Compared to all the other brands I would call this one soft/medium as all others "medium" were pretty firm. This one is just right!

Perfect supportive soft pillow

The perfect pillow that is hypoallergenic. It’s soft but your head doesn’t sink through. Supportive and soft at the same time. Have bought more pillows.

Very firm pillow
Size: Queen (Mid Loft), Number of Items: 1
I'm not sure I received the same pillow as advertised. The pillows I received are extremely firm. I would not classify it as medium. It was also not covered by a cotton case. it had a very sheer gauze like material covering the latex.

Super springy and comfy!
Size: Queen (Mid Loft), Number of Items: 1, Size: Queen (Mid Loft), Number of Items: 1
I’ve been looking for a pillow that offers support but is soft and cushy. I had never tried a latex pillow before, and I was skeptical because I heard it could be hard, but I decided to give it a try. I tried a memory foam and it was waaaaay too hard to be comfortable. This pillow retains its shape, is really soft and plushy, and works great for back or side sleeping. It had a slight smell (not unpleasant though) when we first unboxed it, but it was gone by day 2. The pillow also sprang up immediately on unwrapping it. After a few days it seemed a little bit bigger, but it didn’t really need any time to air out/fluff up, it was basically ready straight out of the box. I’m often picky about pillows because I get headaches from sleeping on my neck in the wrong way, but this one is great and I haven’t had a problem at all. My hubby likes it too :) it’s the favorite house pillow now.
