MH Bulbs

[DiggerDave]

HI, My 175 Watt 10000K bulbs are over a year old. I was thinking of going to a 250 Watt 10000K. Im not sure what kind of ballast I have, will I have to change ballast to use 250 Watts?
Thanks Dave

Yup. You'd need a 250 watt ballast. Can't mix and match MH stuff.

[DiggerDave]

OK how about a 175 Watt 12000k Sunburst?

I like the 14,000Ks by South Pacific Sunlight. You should too. JD

I had the 250 sunburst gave a nice blue colour.But I have heard the 10 k is better for growth.
