I am a first time grower (new card holder) and i have a 175 watt metal halide pendant lamp (actually 2 of them, but one has a bad ballast) from a previous saltwater reef tank that is now a fish only tank.

My question is can I grow 3 or 4 plants with this one 175 pendant and can I use it throughout the entire cycle or do I really need a sodium vapor lamp?

This will be the first of many, many questions I'm sure.

Thanks!
