Ok...I am probably a nuisance but as I see it ...One buys the brightest LED lighting strips ....that are available...5630 leds are nearly twice as bright as 5050 leds and 7020 are brighter than 5630's... so in my mind I would be best to buy 7020's....Being for plants I would be best to get waterproof Strips which are a lot more expensive than non waterproof....according to my research .....
But can one buy 7020 Flexible lighting strips ...I do not know ...if not one could change the design and use non flexible strips..... Next is colour ..should I use cool white or warm white ...What I have read cool white could be the best option ... Next is RGB Strips but I have not found these in 5630 or 7020 LED's ...I have found them in individual colours IE Red Green and Blue....Therefore I presume one could make up ones own ratio of colour by combining these...... It seems to me that these would be easy to connect up with everything available online including clamping clips...It will not cost me a fortune but would I be throwing my money away..I do not know...hopefully i am not on my own and somebody here could give me an opinion... I see there is a multitude of extremely interesting videos on Youtube about LED's ... Regards Ron Last edited by murihikukid; October 16, 2016 at 05:36 AM. |

What ever you do you dont need green light for plants, they dont even see it.
Another thing is if the lights are powerful enough you will need to wear protective glasses from what I have heard. The other is the LED has to give off the red and blue light it cant just be a coated lens. Worth |

Worth ..You have really helped ...I certainly never thought of "coated" lens ...but then I wonder how one can check that .......Re normal light do you prefer the cool white at 6500K for young plants as against the warm light which as i understand is better for the older plant producing fruit..
Thanks Ron |

65K and I have had blooms show up on plants with it just fine.
Never grown to full fruit in the house. I honestly dont buy into the red light spectrum later in growth. Worth |

Ron, forget about the "warm light" nonsense!

Do you have a feel for how much power you're saving with the LED lights?

I haven't read the beginning of this thread yet, but i recently got a few of these. They are working fantastic for me and my seedlings. Way better than anything i had before. My tomato seedlings actually look dark green and lush this time as opposed to yellow and leggy. The LEDS are indeed bright when you first get it, but it's actually not too bad tucked away in a corner on a rollaway shelf. I have two currently connected to an Arduino controlled timer with a relay controlled power outlet.
The item say's it's 100W, but a few comments say that in reality it's about 50W. Still plenty good for me even at 50W! http://www.banggood.com/100W-1131-Re...p-1020547.html There is an interesting thread over on the OpenAg forum about COB LEDS. Basically a COB LED is just one giant LED instead of a bunch of tiny led's in series and parallel. It's up to you to decide which method is better if going the LED route.

Am I the only one here who doesn't use lights to germinate seeds? Forgive me for my ignorance, but I thought the only thing you need is the right temperature in the room and I even read somewhere that light isn't really necessary before your seeds have germinated....
Plus I don't get it...since they don't heat up like old light bulbs, what are led/neon lights supposed to do the seeds? Or do you use them only to provide extralight once the seedlings have already sprouted? |

fritz... I think it depends on where you live. I live in one of the cloudiest areas of our country ( I think) and there is definitely a need for lights.

No, you don't need lights to germinate seeds. (Heat helps up to a point.)
But you need to apply light to the little beasties as soon as they poke up above ground. Their internal food packet runs out shortly after the cotyledons deploy, so they need the food made by the green bits.

The title of the thread is new lights for seedlings not seeds.
Since a seed is in the soil it wont see light anyway. But it needs to see light in at leas a few hours after sprouting. I wait till the first seed sprouts and the lights go on. Worth |

Do sprouts need light to know which direction is up? Or can they sense gravity?
