12000K lighting

hello! what are the plants that can tolerate such high temperatures of lighting???

Almost no plant. Unless you want to keep fry kang kong.

i tried before. plants still grow as normal. but it's too bright.
tank will 95% slow growth rate plants
has switch to 10k mix with 8.5k

why wanna use 12k tubes? for ur CRS?

haha plant growth got increase? when you say too bright meaning got algae ah..or too bright for the eyes?

bro, kelvins is call light temp but not the actual temperature of the lamp.
it's like a rating for the light colour.

eg

2000k = pinkish
6500k = yellowish
10000k = whitish
20000k = bluish.

the most intense light would be the 6500k to 8000k rating (check the lumens)
6500k is like noon sun.. hot hot... 12000k would be like morning sun or evening sun, not so hot.

plants do grow with 12000k tubes. more importantly would be whether the plants you have require intense lighting with the full spectrum of light waves.

thanks for the explanation.. haha but as i sed high temperatures OF LIGHT! i do understand its the coloration.. where do i get info on whether the plants find such intense lighting favorable??

When you say its the actual temperature, as mentioned, it is independent of the kelvin ratings. One 12000k light can be very hot while another 12000k light is tolerable.

Plants flourish under ratings between 6500k and 8000k because it mimics the actual sunlight at noon and contains a good range (spectrum) of colorings. 12000k is good for marine tanks as they thrive under the more bluish lights.

Plants can and still grow under 12000k but it is just like our intakes. You take Subway and I take hawker western. Yours is "better" in quality but both of us still roughly get the food that fills our tummy. Its a very off analogy but I think it is somewhere there.

As always, I recommend going between 6500k and 8000k. Its better to change your equipment to suit your tank rather than you suiting the equipment. Remember, the tank should be centric around your idea of the scape, rather than your ideas coming together from what you have at present.

12000K is for the tank.. its going to be for crs.. but i want to include plants in and i duno if the plants will still grow under those lightings..

Don't worry. They will still grow.
