Hi Steve

i do not know why no member response to you and they have not response to my thread too.

metal head light as you know is commonly use in the reef aquarium.

it is powerful and of course expensive.

you can use MH light for planted tank but it may be an over kill.

planted tank needs a good balance of nutrients, Co2 and light.

if you have a strong light, weak co2 and good nutrients, you are inviting algae to grow in your planted tank.

if you do not have co2 in your tank, i would strongly suggest not to get MH light. get one with 6,500 kelvin and have about 2.5 or more watts per gallon (depending on the numbers of plants {types of plants}).

MH light also keep the heat up, so in the summer you may have problems as most plant would like cold water temperature.

all the best.
