which kelvin is better for nems?

[golf8hdcp]

ok guys quick question.. I have 3 x150 watt hqi with 4x 94 watt pc actinic supplement.

Which kelvin is best for nems 20 k or 14k? The tank is 24" deep.

Thanks

The best I can do is give you a general idea of what each one gives off..


In a very general sensus (all other factors being equal and in a generic setting) the higher the kelvin the lower the PAR. It's generally accepted that bulbs in the 10K range give the best growth but also have a more yellow appearance. With the bulbs you've mentioned I would guestimate that the 14K would produce more photosynthesis within the animal.

Keep in mind it really depends on the animal itself and odds are you may not even be able to tell much of a difference between those two with all other things being equal.

Good luck and FORRREEE!!

Some nems like bright light, some have low light prefs. What type of nem are you looking to put in your tank?

he is already in but its time to ugrade the bulbs

thanks Al 20k is bluer or more vibrant color no?

As a general rule yes that's true. Some brands of bulbs are "bluer" than others and some pack a LOT more PAR than others.

My gig is under 250 watt 10k halide with t5 actinics. I've had him since about April and he's done great. With 150 watters I'd definitely stick with 10k.

Very good point Robert. That does boost the curve in your favor with 150's.
