Hi All! I have two question: Pls help
(I) I have an aquarium of 60''x30''x30'' (LxWxH) setup. The lighting I have in mind is either 4x400W MH or 3x400WMH + T5 supplement. Let's assume other parameters are stable.
Which category should achieve the best growdth rate?
1.) 4xBlue bulb 2000K only (around 420-460 nm peak only) super blue appearance
2.) 4x14000K (combination of 420-460 peak, 540-580 supplementary) White blue appearance
3.) 4x10000K (540-580 peak with 420-460 supplementary) White- Orange Appearance
4.) (3 10000K MHs) + few accinic T5
We know that most folks get a good growth with 10K-14K temp is that because that bulb produce the best PAR?
(II) WHat's the major different between commercial 20000K bulb and industrial blue blub? According to my observation, they are quite indentical in spectrum distribution which always peak in a blue range of 460nm.
