What Spectrum?

[DJDrZ]

So, It's been over a year for my lights...time to get new bulbs.
I have a 4x 65W CD fixture, that is currently running 50/50s. It's a holdover from my FOWLR days, and I am thinking I should change to 10,000K bulbs.

What is the general consensus?


For the record, I only have on 2x65W during the day, unless I am viewing and then turn on the second bank.

I've grown plants under 5000K daylight bulbs to 6700K to 10000K...really makes no difference other than to the eye. I prefer mixing the latter two, or something close to it...

Thanks, I can only find actinic, 50/50, and 10000K in 65 W square pin...any ideas for 5000K or 6700K?

I've never used CF lighting so I'm not much help...but I've grown plants well under 100% 10000K so I wouldnt worry.
