We've got
conversion bulbs to accommodate your every need.
Conversion bulbs make it
possible to run a halide bulb from your sodium ballast or a sodium bulb from
your halide ballast. So you could run a halide to bring your plants through the
vegetative stage then switch to a sodium grow light conversion bulb to finish 'em off
through flowering.
