Is 10,000 k or 20, 000 better for Sps growth

[holyspirit]

heard that 10,000 can make sps grow faster

however for colour, using 20,000 will be better

Assumming same wattage, 10000K, because of higher PAR.

pardon me... but wats PAR?

[BarraCudaTM]

photosynthesis available radiation

Highest PAR is 6500K..but not many people use it alone..because it is too yellowish. Normally they combine with 10000K or 20,000K bulbs.

intending to get 2x250watt Iwasaki with 1 T5 blue plus. wondering how that will look

[Achilles Tang]

IME... very yellow.

If you want... you can come to my place to take a look at the combination of 6500k + blue MH and see for yourself how 6500k alone looks like (yucks).

You need very strong blue lights to get a white look.

What about 2x250watt Ushio 10kk with t5 blue plus??

If you are lookin for BLVs, might wanna consider those singular pendents carried by X Glare.....

They come with 1 x 250W DE BLV bulb and 2 x 70 W Blue bulbs....

that will do in cancelling out the slight yellowish colouration of the BLVs....

You can check the thread in the respective sponsers forum....

a "live: examplr would be the pendent used to light up MLs 3 footer display reef.....
