Hearing about LED grow lights for the first time? Well, these are the specific led lights that can help grow plants. NASA developed this technology, and the primary motive of these lights was to grow plants on other planets than earth but since a few years these lights are available to the normal people and you can buy online easily.

Thanks!
Got them from Ebay.

I got the 50w Warm version.

So far so good, they are still rocking!

Any reason the bottom flooring of my scrubber is almost growing as much or more than my screen is?!

The algae will utilise the red spectrum of light in particular & the other spectrums that makes up the white will be a waste of Watts.

Your 50W light, on each side of that screen, could instead be about 16W of red 660 nm leds

Not really. I ran red LED on one side and blue on the other... growth was almost the same. I don't really know where the color discrimination came from but flow and surface condition had a much greater effect on growth. Try it.

False.

I had 2x50w red grow lights before and the algae didnt grow at even half the speed. Try it yourself.

Yeh, 50W of just red would cause photosaturation

Try just blue on both sides.

the light on each side was directional, minimal bleed through.

Light might be too bright, until the screen fills in more to absorb it.

Sm drop1.4

Hi everyone,

Well, I just received and set up my Santa Monica 1.4 DROP scrubber. It looks really nice. I just used a pump that I had lying around which was a Tetra Whisper 10G air pump. It's really small. Will this work at all with a small air pump or do I have to go larger. I really like how quite the pump is. It's currently quieter than my skimmer.

What wattage led would you recommend? I'm using a crappy cf bulb and it's not working to well.

If this is the one then it's a bit small....

http://www.tetra-fish.com/Products/a...air-pumps.aspx

The 4 bubblers (for the 4 textures walls) each should get good bubble flow. Use that pump for now, but try to get the larger 40 or 60 pump.

LED lights can be 1/4 to 1/2 watt per square inch of screen.

No such thing Karim as plain white light. Plain white light has the full spectrum,
Including RED. The RED is what your algae utilized to grow, as well as some blue. My previous point was, the watts used to generate the other spectrums is a waste, as indicated by the Chlorophyll light absorption spectrum chart i supplied,,, post 9837. There is simply no argument.

I used 450nm on one half of my scrubber and 660nm on the other half. Two one sided scrubbers that alternate. I had really fresh rock, so I feel there was a variety of algae types.

Hands down, the red grew a lot more algae than the blue. I ditched the blue and replaced it with red.

I know what white light is. When I compared the growth rates on white LEDs with blue or red, the difference was negligible. I run bigger systems so power use is important to me, but my results with 100W "white" puck were as good as 100W red led matrix.... same algae weight (and yes, I weighed the batches).

The algae was different, by the way. The white side was darker green and had more variety - red, purple, etc... but weight was ~ the same.

I found that flow and media had a lot more impact.

Yes red always wins. These tests have been done a few years ago.

The algae is getting less PAR on the white side, causing darker growth. You could probably get the same darker growth with reds of half the wattage.
