Hello LuckyThief86,

I'm only have experience with DJ Short's lowryder series of auto's, they don't get very tall.

A 250w HPS or even MH will do fine for a couple of autos. BTW, they seem to do best with abt 20hrs of light per day, but any thing from 18/6 to 24/0 works fine.

Hope this helps you,
OM
