Hello, I am installing a 400watt magnetic ballast with a 400 Ceramic Metal Halide bulb this weekend probably. I already have in my veg/big tent a 600 watt cool tube digital dim-able ballast 250cfm 6" inline fan blowing through venting out of the tent and into a carbon filter. Anyway I am going to move the 600 w/ the hortilux eye bulb over to the left slightly off center and hang the 400 CMH as close as possible but on the right side. So my question gentlemen is should I change out the hortilux hps bulb for a MH or not worry about it since I am installing the CMH right beside it soon?? I am in veg. But is it really worth it to use the MH ??? Opinions please, thank you for your consideration GC!
