Homer,
got a friend with a setup on a 300 he also has dual 400 mh but is using 1000k along with 4 vho actinic and I wanna say 2 or 4 whites dont know the k on the whites...I would recomend probably 3-4 vho blues to help get the color back from the mh....
Good question. I just installed 2 250w HQI's that I am supplamenting with 1 96w 03 PC'c.I like the color. I am in the equipment procurment stages of a 230gal that I will run 3 400w 65k's, 2 250w HQI's and 4 110w 03's on an icecap. these will not be in a "hood" but in a free-hanging custom fixture that I am fabricating.
I originally put 4 96watt true actinic with my 400s. I now have 2 96 watt "blue" actinic. If I were to do it again, I would go with 2 or 4 VHO instead. The 96 watt PCs are completely unstable. I had 3 of mine disintegrate after 4 months of use.
I hear you on that one. I have 2 96w "true 03" that have totally differant color from each outher. When I upgrade I am going to be using the balests for the refuge. What other type of bulbs can I run on the LN electric balest.
