Do you leave your actinic's on when your MH's come on? I have an Outer Orbit 36" with 2 96 watt dual actinics 420/460's and a single 150watt MH... I have always left the actinics on while the MH's are on because I like the color they provide but is that incorrect? Please give me your opinions. It thought I was supposed to leave them on but I have recently heard differing opinions..... Thanks for any inputs..... Also, are the better lights I should substitute? Next MH I am upgrading to the 150MH 14k or 20k. I think. All opinions welcome!!!

Yup, you can leave them on if you like the look.

I think most people use them for dusk to dawn lighting when the halides aren't on also.

Great. and yes they come on an 1 to 1 1/2 before the MH's and stay on that long after the MH.

That is how I run mine, blues on first and off last, with MHs on during the middle of the cycle. I would not switch to the bluer MHs while using the blue PCs, unless you really prefer the deep blue look. Plus, the bluer MHs don't put out as much PAR as the 10ks.
