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.

Dog doesn’t care for it
Size: 1 Pack, Style: Bone
Hard to review product for its durability because my dog has never chewed it once. Doesn’t care about it at all. The bone feels rugged but smells like playdoh. It’s sat on the floor for over a month untouched.

Pawbler FAIL: First time our dog bit the ball, it popped open and dumped all the kibble.
Size: 1 Pack, Style: Pawbler
I would not recommend! We have a 48# dog and within minutes of giving it to him, the Pawbler was open and all of the kibble was in a pile on the ground. I had washed and dried the Pawbler, added kibble, and tightened the lid as tight as possible. Imagine my surprise when, within minutes of giving it to him, the lid was off and all the kibble was on the ground. I thought it was a fluke so then I made an extra effort to make sure the lid was super tight...and the same thing happened. This time there was no food inside so he started chewing on the two parts. Within minutes of that, he'd chewed/damaged the rubber on both the body and the lid. I took it away as I didn't want him to destroy/eat any of the rubber bits. I was surprised he could even get the Pawbler in his mouth. It's heavy and he is a medium sized dog. He has the Benebone Bone, the WestPaw bone, the WestPaw ring that he chews on all of the time and none of those are showing any type of wear so to see this opened/chewed within 15 minutes makes me think this was defective. I am returning and hoping for a refund. DO NOT BUY! Poor value for the money. Not durable. Not chew resistant.

Just what I was looking for to slow my large dog while eating
Size: 1 Pack, Style: Pawbler, Size: 1 Pack, Style: Pawbler
I needed something for my 50-pound dog to slow down her eating. The usual slow-feeder bowls and mats weren't really slowing her down much and I wanted her to have to think a little bit. She's not smart enough for puzzles though. So I got this kibble dispensing toy. My dog is not a chewer so I don't have to worry about her destroying it. LOVE: holds a little more than a cup of kibble, dispenses different sized kibbles, heavy weight so it wobbled around a lot without going too far away, QUIET- I couldn't bear the noise of hard plastic dispensers clacking around and this one is very quiet on our hardwood floors, kept the dog busy for at least 20 minutes. It's really all I was hoping it would be. And, well, as you can see in the video, the cat is happy about it too... As with all of these dispensers, there will be a couple of kibbles left inside that are hard to get out. But that gave my dog something to do overnight. She spent a long time getting that last kibble out. The slight scent they add to the natural rubber is not a problem at all. This dispenser is absolutely worth the money, it's going to last us a very, very long time.

People are doin it wrong
Size: 1 Pack, Style: Cone
Cheap and durable and huge. The bad reviews are from people who aren’t using it right. Step 1) plug hole with a smear of peanut butter. 2) put a low calorie but appetizing mix of whatever you want: yogurt, pate, pumpkin puree, blended with frozen veggies on the walls 3) freeze cone for 30 mins. Hole will be sufficiently plugged to add liquid. 4) fill the rest with water or bone broth and freeze overnight to make it a changing ice block.

Durable
My dogs love this one so much that we had to order another one so they wouldn't fight over it. They usually destroy toys in less than a day, but this one has lasted months now.
