Hi there Im new
and Im in search of someone who maybe able to help and thought the hydro guys might know.
I need to grow algea under leds for a type of filter on a marine aquarium called an ATS
what im tring to find out is if algea prefer a special type of colour as there are many options.
My thoughts are to go with a vegative quad band
led @ 50w as algea dosent flower (I think) so better range of blue nm then red nm would do it, quad also have white and orange, maybe orange is what it really needs but not sure what that range actually does to the plant.
people who have ATS use
cfl, t5s etc in the 4000k range as they say it has a higher red spectrum in it and they get better results.they have also used 6000k and still 4000k are better.
any help in the right direction would be great...
this is an email I got from the led supplier about the range they have.
Dear Mr.Shane Grant,
Thank you for your prompt reply!
Here I send the PI of quad band 50w led grow light for you as attached file.
All of our price are in $US.
Blue light is good for vegetatives and the red light is good for flowering and budding, you can choose the ratio of the light, which have wonderful efficacy for the plant.
Vegetative(Dual-band): Red: 620~630nm / Blue: 450~465nm R/B ratio: 8:1 or 7:2
Flowering(Dual-band): Red: 660nm / Blue: 450~465nm R/B ratio: 8:1 or 7:2
Vegetative(Tri-band): Red: 620~630nm / Orange: 610~615nm / Blue: 450~465nm R/O/B ratio: 7:1:1
Flowering (Tri-band) : Red: 660nm / Orange: 610~615nm / Blue: 450~465nm R/O/B ratio: 7:1:1
Vegetative(Dual-band): Red: 620~630nm / Orange: 610~615nm / Blue: 450~465nm/White R/O/B/W ratio: 6:1:1:1
Flowering (Dual-band) : Red: 660nm / Orange: 610~615nm / Blue: 450~465nm/White R/O/B/W ratio: 6:1:1:1
Yours sincerely,
Michael
The ATS is used to exprot
nutrients from the water like po4. I can provide more info if needed. the colour of the algea goes in stages but the end species that grows over a few months to get to will be vibrant green.
