Lighting help?

Hi Eric,
I think the plants will adapt to whatever light in that Kelvin range (or even lower) so the "best" will depend on what you like to look at. Only you can determine the length requirements since it has to fit inside your hood/fixture. The wattage will depend on what level of nutrient/CO2 dosing and growth you are prepared to execute.

I'm afraid I'll have to plead ignorance on all that lunar landing lighting stuff since I don't look at my tank at night. The daylight bulbs are typically rated near 7000K and this produces a nice clear image with the greens and any yellows of the plants really standing out. As you go lower towards 6000K and below the light is in the pink and purple which if used too much seem dim and eerie to me, but if used in sufficient quantity can help highlight the reds in the plants. Up towards the 10000K doesn't do have any redeeming quality for me but some may like it. In any case these are all just personal preferences and the plants will use whatever you give them. Withing this band one Kelvin rating doesn't seem to be any more advantageous than another.

If you want a high light, high maintenance tank then multiply you tanks volume in gallons by three or more and that the total number of watts you need. If you are new to growing plants, or if you want lower maintenance requirements, you may want to consider multiplying by 1.5 to 2 and call it good. So you see it depends on your goals and ambition with the tank, therefore "best" is subjective.

Hope this helps.

Cheers,

i have a tank with 4 T5 (bulbs) not dimmeble.

if its not possible i really want to be close.



thanx

 

These pictures are often enhanced with photoshop, like hue, brightness and contrast. It's impossible to say how to get this light by looking at the pic. It seems to me though you like the blueish light. You can try to imitate it by using typical plant bulbs and high K lights, in the range from 8000 to 10000K. But it's a compromise. High K lights won't look good on red plants.
Still it's a matter of experimenting, and you could end up with a lot of bulbs that you don't really want.

I use just 6500K bulbs. They are cheap and a good average between red and blue with lots of green for viewing purposes.

 

Thanx Dutchy,

You just fixed my problem. I'm good with photoshop... lol

well i am going to experiment with it.


Cheers
