Does anyone have a link to a lighting spectrum chart

[Pixelfish]

I am trying to figure out the general required spectrum for orchids. I did not find an actual chart using the forum search feature here. I did however, find some controversy over LEDs which make me want to look at an actual spectrum chart. I believe LEDS would work great (But I know nothing about orchids.).

I have a very nice programable 24 hr LED fixture I used for a 2' deep salt water aquarium and it provided enough lighting at the very bottom to keep anemones happy. If these lighting fixtures are superb replacements for T5 fixtures in the reef aquarium, how is it not for orchid lighting?

Hello, here I leave some pictures on the spectrum of chlorophyll and LED lights that I have which has LEDs of different colors:



This is a picture of my settings LED spotlight is a special focus to see the green color of plants while having good growth, you can see the different colors you have.



In short, you would have to know what is the spectrum that provides the light that you have, if made ​​to grow plants. There are white LEDs so that plants can grow, but are specific to plants. For example these:

Here he explains the different spectra can have an LED:

Les spectres Rainbow - Blue - Visua | Culture sous LEDs | BloomLED

Here special bulbs sold for the growth of plants, for now only send to Canada. To our orchids and enjoy them believe that the spectrum "VISUA" is best for us.

I'm very happy with my LED spotlight, there are always flowers grow, now I have: a dendrobium type phalaenopsis finishing flowering, a Bulbophyllum and Brassocattleya Binosa 'Wabash Valley' developing a floral stick.

I hope it's for your help.

A greeting.

I would recommend against using an aquarium LED light for plants. Because of the attenuation and shifting of the spectrum by water, their output spectrum is nothing like that needed by non-aquatic plants.

check this one out ecotechmarine.com and look at the radion-xr30w . I would think its more than enough because they make these things to replicate the sun. Like I siad I know nothing about the orchids requirements so I am trying to get smart on them. The LEDS have come a Huuuuge way and alot of reefers are swithing to them after they swore never to do so about 3 years ago. If alot of people are using T5's or PC's for Orchids they might want to check out the LED lighting now days. the product line went for 4 companies to about 40 in the last 3 years.

In addition to the absorption spectrum of chlorophyll posted above, "photosynthetic action spectrum" is more relevant. You can google it, and you can get a typical plot.

Your LED has lots of usable lights (at the blue end) and pretty intense, so plants can do photosynthesis well. But it seems to be more tuned for coral growth (shifted toward lots of blue). The question is whether physiological reactions other than photosynthesis will be affected by the relatively low red light. The plants may grow well, but it may be difficult to flower them for "some" species (e.g. a "medically" relevant weed). What kinds of orchids are you growing? Similar to Ray's recommendation, I wouldn't buy the one you have if I were to buy a new fixture. But since you already have it, you should give it a try. It won't kill orchids.

I'm recently trying Sunshine Systems GlowPanel 45.
GlowPanel 45 LED Grow Light

I used to use 90W 5-band UFO LED, but the fan was noisy, and I didn't like the uneven intensity. Since I grow only low-light orchids and the efficiency is important for me, I'm happy with the 28W system. 2 of these can cover about 4x2' area.

yeah thats good to know! I think your right, My lights don't have alot of red as the ecotech or the one you were showing. I will look into some more. It covers the 7000k-2400k and during hte brightest part of the day its programmed to the blue to be about 4% and the royal blue at 2% and the white to be at like 85% turned up I will look at what that matches up with the red you were talking about. I appreciate the link. LEDs is def the way to go that I am looking for. It was either that or T5's. They are much cooler, slimline and more controllable and less of the electric bill.
thanks again!
