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

I'm only planning on growing two autoflowers at a time from now on, maybe three at most. So I went to the hydro store to see what I could get for the next grow, because this 24" 4 bulb T5 I got just isn't penetrating the canopy. They had these 250W Switchable Sun System enclosed ballast mini-systems for $200, or $240 with an Agro Sun bulb. Would the 250W be enough for two plants, or should I go with the 400W? I'm growing a medical Rating: 5
