Switching to HID

[moblaxy]

Hello all,

I am a long time stalker on the boards and fairly new to orchid growing. I currently use a T5 set up with a mix of blue and red bulbs. I want to switch to using HID bulbs in order to grow my collection and also add some more bright light loving species, Cattleya, Vanda etc. My question is do I still need to provide blue and red light with the HID's (MH and HPS) or would the MH be enough to get everything to bloom. I am considering a dual bulb HID (Growzilla) but the cost of that light is a little more than I'd like to bear at the moment. Any advice is appreciated....Thank you..
