T5 to replace VHO

[Tracey2]

The mh's seem to take up so much room with the giant reflector, could I put 2 T5's inside the mh reflector or would it get too hot?

I am thinking vho's on for 2 hours then 2 T5's come on for a 2 hours then mh's come on for 3 hours, then mh off, T5 off vho off, moonlights on, would this combo be good for colour/growth?
