It seems you kept the kits just to come in here and try and keep up the LED vs HID shit.
No. I kept the 315W CMH kits so I can use them in their most effective places in a setup that's otherwise advanced beyond the light bulb.
Turns out that they're plenty effective in veg, in part because they're an omnidirectional light source, makes them great for training a bunch of plants to grow vert.
If you just want a cheering section for your choice in lighting, that's cool but self limiting. If you want hard nosed comparisons of the tech vs other options, this is the right place.
