Hey good luck bender, 1000watts should be more than enough. I've never used a conversion bulb, keep us posted on how it works for you.

Hey torog, What part of Texas are you from? I'm a little north up here in god's country Most hydro shops carry the conversion bulbs also.

Nosehit Reviewed by Nosehit on . A light question My grow box is 3' x 4' and I have both a 400w hps and a 1000w MH. I need to know which one would be best to use or should I use the 1000w just for the veg and the 400HPS to bud. or can I just use the 1000w from start to finish? If I get more air flow I may try to use both but that seems like a lot for a box this size. that would put me to almost 120 watts per square foot. THANKS Rating: 5
