I agree with almost everything people are saying. I used to have MH
and the only things I didn't like was the power usage and the extreme heat. Almost all of the bulbs mentioned produce heat, but MH
was too hot. You will never need a heater and mine was atleast two feet above the tank. During the summer I had to use a chiller. I use VHO
and love them, they are not for everyone. I also us PC
and if you are interested in PC
shoot me and email. I can point you in the right direction to get them cheap.
