I pull the flat of plants from under the LED lights every couple of days to inspect their growth and monitor water. I installed the red & blue lights under a lower shelf so I am not especially aware of the color as I work in the basement! You're right - it messes up my eyes! I am not going to purchase white LED lights. I only have the red & blue ones thanks to my brother, who decided not to use them. I am a cheapskate - I will simply stay with the fluorescent shop lights for the rest of my plants as I have had very satisfactory results using those over at least 20 years, proving to me that actual grow-lights are not really necessary (at least to a li'l ol' backyard gardener like me). My hundreds of seedlings each year turn out stocky and a nice dark green (part of the latter thanks in no small part to my worm compost in the transplant mix, I am sure!).

I understand not everyone has $150 to spend on a plant grow light and that other solutions exist on the market, but this product suits my needs and I feel it was the best, long term investment I could make to accomplish my goals. Ultimately, the quality of my plants speak for themselves and I am very happy with the investment I made. And come on... "Your usage of the word 'need' is that of a schizophrenic". I used the word three times, and that is a very immature way to respond. We're adults here, thankfully neither of us schizophrenic. I am trying to share knowledge with you and others reading this, but you shoot down what I say without providing evidence to your claims. I am just reporting to you what other companies and various studies done by universities and NASA are saying. The LED grow light market is currently worth $395 million (2014) and is forecast to reach $1.8 billion by 2021. If what you are saying is correct, that number would be significantly smaller. https://globenewswire.com/news-release/2015/10/29/781299/10154495/en/LED-Grow-Light-Module-Market-at-395-Million-in-2014-Are-Forecast-To-Reach-1-8-Billion-by-2021-MarketResearchReports-Biz.html As for "need", yes, you need a ratio that has significantly more red (660) than blue (450). Here are an abundant amount of studies that talk about the need for that ratio and the usefulness of 24% or less of green (where more than 24% green causes a negative effect). - The National Aeronautics and Space Administration’s (NASA) Biological Sciences research group has concluded that light sources consisting of more than 50% green cause reductions in plant growth, whereas combinations including up to 24% green enhance growth for some species. These used red/blue led lights with added green. - http://www.actahort.org/books/711/711_11.htm ---- A 2nd study that supports NASA's results. They tested lights that had 0%, 24%, 86%, and 51% green light. 24% did the best. http://hortsci.ashspublications.org/content/39/7/1617 ---- A 3rd study that shows the addition of a small amount of far red AND the addition of green was useful. http://hortsci.ashspublications.org/content/43/7/1951 -A paper that talks about the importance of 450nm light and 660nm light. it shows that 660nm contributes to the plant photosynthesis. http://www.actahort.org/books/440/440_20.htm -A study that talks about the ratio of red/blue being 4/1 along with the addition of green and the effects. http://pcp.oxfordjournals.org/content/45/12/1870.short -Research done by one of the top grow light companies, showing the need for 660nm light. These lights sell for much more than the Asepct. "The 624nm region has the highest photosynthetic relative quantum yield for a range of plants. At the same time, its action on red-absorbing phytochrome is considerably weaker compared to that of 660 nm red light and can be used to balance the phytochrome equilibrium towards lower values (closer to those of daylight) than those achievable with 660 nm red light, especially when used together with 730 nm red light." https://www.illumitex.com/impacts-colored-light-plants/ ---- You can see the spectrum of light this company uses, clearly they support the idea of the 1-4 ratio of light needed for optimal plant growth. https://www.illumitex.com/full-spectrum-light-plant-growth/ For the far red, no, a regular incandescent bulb has too much far red and IR ways, it will kill the plants. Once you start going above 750nm you lose the Pfr to Pr conversion and start in to phytochrome mutation not manipulation in plant growth. You need only a little for the Emerson effect to work. Here are an abundance of studies to get you started on. http://microbiologyprocesses.blogspot.com/2011/12/photosystem-i-ii-red-drop-effect.html http://jgp.rupress.org/content/16/2/191.full.pdf http://www.life.illinois.edu/govindjee/Electronic%20Publications/1963/1963_Gov.pdf http://www.plantphysiol.org/content/39/1/10.full.pdf Finally, the cheap Chinese LED you found. Yes, the LED is $5 but the quality could be anything. My experience is buying Chinese tech products has resulted in a total waste of my time and money. Even if the LED works, you will need to add a heatsink, power supply, optics, ect. Then you need to make a body for the light, buy 15 feet of wire, buy a power cord, and learn basic electronics to build the entire light. Good luck finding quality parts to power that light for under $100, then the question is, what is your time worth? Do you claim to know what parts you need already, how to rate a heatsink, and have the time to research and buy all of this? Anyway, I want to reiterate....I understand that not everyone has $150, but I do, and I invested it in an LED grow light that would not only grow my plants indoors but look great doing it. My plants and home speak for themselves...a worthy investment. Have a nice day. -Paul

Interesting! I will keep this in mind. I have a room I want to make into an "indoor garden" but I need to get my outdoor gardens complete first!

hi started some seeds under led light wow what a different also started some petunia small shoots from the fall these led light really make a different now my daughter brought me some roses I will put them in earth and see what happen hoping for some roots any one else have you tried the led lights
