howfar into the canopy does a 400w digital hps go

so like how far in feet?

Light from a 400w HID is effective for about the first 3 feet.

uh well the best is a 400W in a cool tube. pretty much you can get the light about 8-10 inches away.

anyways get some cfls on the sides to support your crop better:hippy:
