Halogen bulbs are incredibly inefficient and are not appropriate for growing. If you are going to be doing a small/micro grow, stick with CFL or T5.
A little bit of reading or searching would have shown you that halogens are no good at all for growing MJ.
Oh okay. I;m using two daylight CFLs right now in my grow anyways. I appreciate the help and stop by my grow to help me there too
