HPS bulbs....the extra K, is it worth it?

The Syvania Grolux is $90+ in the 600W and it has a 2050K on the spectrum. You can buy a 2000K HPS bulb that puts out the same 90,000 lumens for $30+ at 1000bulbs. I have a MH bulb that I used for 30 days that I bought from HTG that has 6000K at 72,000 lumens.....was not impressed at all. I am still in the early vegitative stage.

I have had the same results from a 89.00 dollar "enhanced" bulb as I got from the Home Depot 25 dollar hps. Hope that helps ya out. Peace
